HOW AN AIR CONDITIONER WORKS
The job of your home air conditioner is to move heat from inside your house out. First, the air is cooled by blowing it over a set of cold pipes called an evaporator coil. The coil is filled with a special liquid called a refrigerant, which changes from a liquid to a gas as it absorbs heat from the air. The refrigerant is pumped outside the house to another coil where it gives up its heat and changes back into a liquid. This outside coil is a condenser which the refrigerant is condensing from a gas back to a fluid. The compressor is also used to move the refrigerant between the two coils and to change the pressure of the refrigerant so that all the refrigerant evaporates or condenses in the appropriate coils.
THE AC FILTER v HEPA FILTER
Air conditioners are beneficial only to the extent that they help circulate and filter indoor air. Almost all air conditioners contain a filter that will remove large particles like dust, lint and dirt.
HEPA filter removes 99.97 percent of all particles that are 2.5 microns or larger through interception, impaction and diffusion.
The air purifiers at Purlife are using HEPA filters which removes 99.97 percent of PM2.5. It complements the air-conditioning to provide better air circulation and ensures that the air indoors is clean. Call 6702 0306 for a complimentary indoor air quality check.
