Heating, ventilating and air conditioning (HVAC) equipment are highly desired these days due to particularly harsh temperature conditions at most times of the year. HVAC equipment can help in heating or cooling a commercial structure to maintain it at a comfortable temperature and humidity level. It can help in supplying fresh outside air to an indoor environment to get rid of airborne contaminants like odors or volatile organic compounds (VOCs) that are emitted from cleaning chemicals, interior furnishings, etc. If properly maintained, this type of equipment can be helpful to achieve a pleasant indoor environment throughout the year.
However, it’s also important to understand the different types of HVAC systems that are available and hence we take a look at them over here one-by-one.
- Chilled Water System – For establishing this type of system, a chiller plant is also required to be set up. Throughout a building, liquid water flows through chilled water coils. The liquid water is chilled to the desired temperature by the chiller plant through vapor compression technology technique. Then, it’s pumped back through the air-to-water heat exchangers and conditioned air is then supplied to the needed areas of a building.
- Cooling Only Split-System – A split system is usually a mix of an indoor air-handling system and an outdoor unit for condensation. The indoor unit typically consists of an expansion device, air-to-refrigerant cooling coil, and an air fan while the outdoor unit may have a condenser coil along with a compressor. Little commercial buildings can generally stand to benefit from this type of HVAC system as in addition to a cool gust of air, they also tend to provide a high energy efficiency rating that can help in saving energy and electricity cost. However, if heating is also needed, then an alternate heating method may also have to be deployed such as a gas or electric heating technique.
- Cooling Only-Packaged System – For achieving commercial hvac phoenix also offers this type of system which is, more or less, similar to the Cooling only Split-System. The only difference between both these systems is that here, all the components that were described earlier, are combined in a single unit. Hence, air ducts have to be used for the movement of air, conditioned or otherwise. The indoor air moves through the air duct to the packaged system and the conditioned air circulates through the air distribution system.
- Heat Pump – A heat pump resembles a Cooling Only System and can either be a split or packaged system but with an exception. Here, a special valve is used in the refrigeration piping so that a refrigeration cycle can be achieved in reverse also. This way, a heat pump can cool an indoor environment and when the valve gets reversed, it can also heat an interior. A supplementary electric heater can be used with it in case of extended colder spells as during that time, a heat pump may need a defrost period while the heater will heat a building interior.
Apart from all these commercial hvac phoenix also offers some other techniques like the Packaged Terminal Heat Pump and Window Air Conditioners. Whichever HVAC technique is used at a commercial place, it must be energy efficient, reliable and durable, a reason why these are abundantly used in Phoenix.
