According to most environmentalists, the ozone layer is getting depleted by greenhouse gases, some of which are emitted by HVAC equipment. This applies for all types of systems, including central, portable and wall-mounted AC units. The ozone layer is what protects the earth from harmful ultraviolet radiation. The gradual depletion of this stratum increases the rate of UV penetration, which permanently raises the earth’s temperature in a process known as global warming. How A/C Systems Work Air conditioners are comprised of internal electric coils and an electric pump to transfer air between the outdoors and indoors. The cooling mechanism, known as the evaporator, is what transmits cool air into the house while the hot coil (condenser) releases warm air outdoors. A compressor pump is included to move the refrigerant between these two components, alternately changing it between liquid and gaseous states in order to move the cool and warm air. Do HVAC Systems Emit Greenhouse […]
