Cincinnati Air Conditioning systems provide comfortable, breathable indoor air by controlling temperature, humidity, movement and quality. They are based on a refrigeration cycle.

Air conditioners range in size from portable units for vehicles and single rooms to multi-zone ductless systems for larger homes. The smallest conventional air conditioners are often called mini-splits. A split system consists of an outdoor condenser unit and an indoor evaporator coil.

An air conditioning system has sensors that can sense the ambient temperature of the home or office. They send out signals that tell the unit to turn on or off based on the current temperature. These sensors can detect infrared radiation that comes from objects in the room and convert it into electrical signals. The signal then translates into the desired setting on the thermostat.

The ideal cooling temperature varies from household to household, and the comfort level depends on many factors such as humidity, season, ventilation, and energy costs. It’s best to balance comfort and cost by setting a temperature between 72 and 78 degrees while you’re at home. Leaving the air conditioner at this temperature will help to lower your summer electricity bill.

When you’re away from the house, it is best to set the air conditioning higher than that. Leaving the windows open and running fans can help to bring down the indoor home temperature, while still providing adequate cooling when you’re not at home.

You can also try to minimize the difference between your AC temperature and the outdoor climate by using fans, lowering the thermostat settings, or both. These strategies can help your air conditioner work smarter and not harder.

The efficiency of an air conditioner is measured by its COP (Coefficient of Performance). The higher the COP, the more efficient the air conditioning is. There are various factors that influence the COP, including the refrigerant used, compressor type, and more.

There are also different ratings for air conditioning units such as EER and SEER. EER stands for Energy Efficiency Ratio and SEER stands for Seasonal Energy Efficiency Ratio. SEER ratings are based on the average efficiency of an air conditioner over a season, taking into account a range of outdoor temperatures.

It is recommended to choose an air conditioner with a high SEER rating. This will not only help to reduce your energy bills but will also save you money in the long run. You can easily check the SEER rating of an air conditioner by looking for it on an Energy Guide label or online.

Humidity

Humidity is a measure of how much water vapor is in the air. The amount of vapor in the air can vary according to the temperature and other factors, such as air circulation, whether there are leaks in your home, or how often your AC runs. Humidity can have a variety of effects on a homeowner, from skin and eye problems to static electricity.

An optimal humidity level helps to keep you and your family comfortable, especially during the hot summer months. The exact humidity level that is best for your home will depend on personal preferences and regional climate, but a good rule of thumb is to aim for a relative humidity (RH) of 40%-50%.

Too much humidity can create a number of problems in your home, including mold growth and musty odors. It can also lead to rot in wood flooring, furniture or musical instruments, and it can make a house feel muggy or clammy. It can also dry out a person’s skin and make them itchy or cause chapped lips, sore throat, or nosebleeds.

High humidity can also increase moisture inside air ducts, which may lead to mildew growth or mold spores. These spores can then be circulated throughout the home by the air conditioning system, which can cause health effects and reduce indoor comfort.

Humidity can have a negative impact on heating, as well. The higher levels of moisture in the air can make a room feel warmer than it really is, causing the HVAC system to work harder than necessary to heat the space. It can also cause static electricity, which can damage appliances and expose electrical wires to a fire risk.

The simplest way to solve a problem with humidity is by using a humidifier. A humidifier adds moisture to the air before it enters the ductwork of your HVAC system, helping to prevent it from feeling cool and reducing static electricity. Humidifiers are available in a variety of sizes, so you can choose one that suits your space and needs. A professional will be able to assist you with choosing the right humidity control for your home.

Ventilation

Ventilation is the movement of air from the outside into a space. It can be accomplished through natural or mechanical means. It is an important factor in maintaining indoor air quality. The purpose of ventilation is to bring in fresh outdoor air, diluting and displacing indoor pollutants.

Most residential and commercial air conditioners are designed to provide ventilation in addition to cooling the indoor air. They do this through the use of an evaporator, compressor, condenser and expansion valve. A duct system is often used to distribute this air throughout the building.

The evaporator is a coil that is capable of absorbing heat and moisture from the air. A fan blows the air over this coil, causing it to evaporate. The resulting liquid refrigerant then moves into the compressor, where it is heated by the motor. Then the hot liquid moves into the condenser where it cools down. It is then pumped back into the evaporator where it is again blown over the coils and into the room, providing both air cooling and ventilation.

The compressor and condenser also work to reduce energy consumption by using a refrigerant that is an environmentally safe hydrocarbon. Typically, this liquid is recycled from one cycle to the other by using a drain line, thereby reducing waste.

In modern buildings, the ventilation system is typically controlled by computerized sensors that monitor conditions in a room and report to the control systems. This data is then used to calculate the required fan power for optimal operation. The resulting control algorithm is applied to the motor and other components of the unit, adjusting operating parameters as needed.

Aside from the cooling of indoor air, a ventilation system can also help to control humidity. High humidity levels can lead to mold growth and other problems. Ventilation is also important in humid climates, because it helps to disperse water vapor in the air, preventing it from sticking to surfaces and creating a humidity problem.

Most homes in the northeast and southwest are well suited to natural ventilation, since temperatures and humidity conditions can be relatively mild during most of the year. However, in these areas, a balanced ventilation system that is supplemented with an air conditioning system may be necessary to ensure proper air circulation.

Heat Pumps

Heat pumps connect to your ductwork and transfer thermal energy between the air outside your home and the air inside. This makes heat pump systems more efficient than electric resistance furnaces or baseboard heaters. Today’s air-source heat pumps can reduce electricity use for heating by 65%, compared to traditional electric furnaces. They can also dehumidify more efficiently than conventional central air conditioners, resulting in lower energy consumption during summer months.

Air-source heat pumps are available in two configurations: air-to-air and direct expansion (DX). In air-to-air heat pump systems, the evaporator coil is located in the ductwork or in the house. In DX systems, the evaporator coil and condenser are located in an outdoor unit.

The performance of heat pumps varies by climate and installation. Energy efficiency regulations set minimum seasonal efficiencies for air-source heat pumps, and some provinces or territories may have additional requirements. Check the NRCan Air-Source Heat Pump Sizing and Selection Guide for more information.

Air-source heat pump performance has improved significantly over the last 15 years. Some units now achieve SEER ratings of 42 and HSPFs of 13. These improvements are largely the result of advances in compressor technology and heat exchanger design, which allow heat pumps to operate at higher capacity and efficiencies in cold climates.

To maximize the seasonal performance of heat pumps, select a model with a high HSPF, and a low sound rating (decibels). A long defrost cycle reduces a heat pump’s seasonal efficiency. Avoid unnecessary defrost cycles by selecting a unit with demand-defrost control. These systems start the defrost process only when needed, to minimize supplementary energy use and heat pump run time. In addition, minimize energy losses by reducing air leakage and insulating ducts (see Minimizing Energy Losses).

Ductless Systems

Ductless systems, also known as mini-splits, allow cooling and heating to be added to a home or business without having to install extensive distribution ductwork. This makes them a perfect solution for new rooms or renovations, sunrooms, garages and other areas that were previously not considered an option for air conditioning. They are easy to maintain and have a low cost of installation. A ductless system can have up to eight indoor air handler units connected to one outdoor condensing unit. Each air handler has its own remote control that controls the temperature in that room.

With a traditional HVAC system, ducts act like highways for treated air. Unfortunately, they also provide a place for dust, debris and other contaminants to collect. Regular maintenance is crucial to keep the ducts clean and free from these harmful materials, which will save you money on your energy bills over time.

A ductless system doesn’t require ductwork, so the air handling units can be installed in small spaces such as walls or ceilings. Installation is completed quickly and with little or no damage to your building structure. Ductless systems are quieter than traditional HVAC equipment, as well. They are a perfect fit for older homes or those that have no attic, crawl space or closet space for ductwork.

A ductless system is very energy efficient. Because they only operate for smaller spaces, utility costs are much lower than a centralized AC system that has to work hard to push air through the ducts. Zoning is another great feature of a ductless system, since you won’t waste money on cooling rooms that aren’t used. This is an especially important benefit in a large home or office.

Gas Furnace

Whether it’s natural gas or propane, a gas furnace converts cool air into warm air and distributes that air throughout the house. Like other hvac systems, your gas furnace has many components that work together to keep it functioning properly. A basic understanding of how your system works can help you troubleshoot problems when something goes wrong.

The heart of any hvac unit is the heat exchanger. This series of thin-walled metal tubes keeps the combustion process separate from the air blowing out of your home through the blower fan. The cold air blown over the heat exchanger is warmed, then redirected into your home through ducts. A blower fan carries the air over the heat exchanger, and there’s usually a thermostat that tells the blower when to turn on.

Inside your furnace is a circuit control board that interprets electrical signals from the thermostat and from its own internal sensors. If the thermostat sends a signal that it’s time to produce heated air, the control board tells the gas valves and burners to open and ignite.

Once the fuel is burned, it’s exhausted through a flue. The exhaust gases can’t just disappear into the air, so the flue is tasked with collecting those by-products and directing them out of the house. There may also be a carbon monoxide detector installed to prevent dangerous leaks.

The gas supply lines should connect from the gas meter to an internal gas valve and manifold. There’s usually a shutoff valve located near the meter that can be opened to isolate the gas if necessary. The piping should have a drip leg to prevent water condensation from leaking into the gas line, and it should be pressure tested with an inert gas such as nitrogen.

Electric Furnace

Electric furnaces operate similarly to gas and heat pumps, though they use electricity instead of natural gas to warm the home. Using a blower fan, they pull air into the system and through a heat exchanger. Then, the heated air gets pushed through the home’s ductwork and into each room. The thermostat signals the system to start up and shut down as needed to achieve the desired indoor temperature.

The power that drives the heating elements of an electric furnace is supplied by 1-2 large wires that connect to the unit’s breaker box. These lines carry 240 volts of electricity, which the electrical transformer inside the heater reduces to a lower voltage. It then sends 24 volts to the sequencer, which determines whether or not the system should turn on.

When the sequencer signals that the furnace is starting up, it sends those 24 volts to the blower motor and to the heating coils. The coils heat the air that is being blown by the blower through a process similar to that used in a hair dryer. Once the thermostat indicates that the house has reached a set temperature, the sequencer shuts off the heating elements and the blower fan.

Just like other types of hvac systems, a properly sized electric furnace is key to its performance and longevity. A professional can help you select a furnace that matches your budget, square footage, layout, and climate zone. A well-sized system is also more energy efficient, saving you money on utility bills. If you want to maximize your efficiency, pair it with a programmable thermostat. You can also opt for zone heating, which allows you to control how much air goes into each room of the house.

Air Conditioner

Air conditioners are designed to cool your home, removing heat and humidity from the air and pushing it outside through ductwork. There are several variations of AC systems, including central cooling units, portable window units and ductless mini splits. However, the fundamental processes and parts remain the same for all of them.

A typical AC system contains the compressor and condenser in an outdoor unit, the evaporator coil inside your home, and a blower fan. The evaporator coil is covered in fins that absorb the heat energy from the air, and the blower fan circulates the cooler, dehumidified air throughout your home. Air conditioning systems also come in multiple speeds, sizes/capacities (measured in “tons”), and SEER ratings. SEER stands for Seasonal Energy Efficiency Ratio and it’s used to compare the efficiency of different air conditioners. The higher the SEER rating, the more efficient the unit.

The refrigerant in an air conditioner starts out in a liquid form and moves to the compressor. The compressor is the heart of an AC and it uses the majority of the system’s power. It squeezes the cool refrigerant vapor and increases both its temperature and pressure significantly.

When it reaches the evaporator coil, the heat energy in the air is absorbed by the evaporator and the refrigerant vapor evaporates. The resulting water condensation runs down the coil’s fins and drains into the pan.

Then, the refrigerant returns to the compressor where it begins the cycle all over again. If the air flow is too low in your evaporator coil, it will lead to poor dehumidification and cooling. Likewise, if the airflow is too high in the compressor, it may overwork the system and eventually freeze up.
