Within limits, the same amount of comfort is the result of a combination of factors within a residence. Conditions for constant comfort are related to the operating temperature. The perception of comfort is related to each person’s metabolic heat production, the transfer of this heat to the environment, and the resulting physiological adjustments and body temperature.

Three Types of Air Conditioning and Heating for HANOVER, VA:
There are three principal types of central air conditioning and heating systems. They are all air, all water and air processed in a central air handling apparatus. In one type of all air system, called dual-duct, warm air and chilled air are supplied to a blending or mixing unit in each space. In a single duct all-air system, air is supplied at a temperature for the space requiring the coldest air, then reheated by steam or electric or hot water coils in each space. A complete HANOVER, VA air conditioning and heating system is capable of adding and removing heat and moisture and also of filtering airborne dust and odorants from the space it serves. Systems that heat, cool, humidify, and filter only, for control of comfort in the winter, are called winter air-conditioning systems; those that cool, dehumidify, and filter only are called summer air conditioning and heating systems. These systems must be fitted with proper controls to maintain design levels of temperature, relative humidity, and air purity.
Air and Water Systems in HANOVER, VA:
Most HANOVER, VA air conditioning and heating units operate by ducting air across the colder, heat absorbing side of a refrigeration apparatus and directing it back into the air-conditioned space. Some form of thermostat controls the refrigeration apparatus. In water-cooled air conditioning units, the waste heat is carried away by a flow of water. For recirculation in water-cooled units, a cooling tower is used. This apparatus maintains a constant level of water in the system and replaces water lost by evaporation. The development of small self contained systems has greatly expanded the use of air conditioning and heating in homes. A portable or window-mounted unit is usually adequate for cooling and heating when equipped with electric heat, only one room.
Often home heating systems are matched compatible ac equipment to provide complete air conditioning for a home. Usually, this is done by combining a heating device and a cooling device in one unit. In regions where the outside temperatures do not fall too low, heat pumps are very popular. In warm weather the heat pump acts like a traditional air conditioner, removing heat from the indoors and delivering heat to the outdoors. In cool weather, it removes heat from the outdoors and delivers heat to the indoors.
