At least, you will be able to talk intelligently with a contractor who is fixing the problem. One place to start is with your home's heat pump. It serves two functions: to heat and cool your home. A 'central air system simply cools the house. Air conditioning systems operate the same way the heat pump's cooling side works. Here's how your heat pump operates: The compressor compresses Freon gas when your heat pump unit is in the air conditioning mode. (It does this in both the heating and cooling mode.) When you compress gas, as with anything, you develop heat. You get a high pressure gas that is very hot typically between 190 to 240 degrees. The hot gas gets pushed into the outside coil. The outside coil's fan draws the outside air across the coil. The 90-degree outside air is significantly cooler than the-gas inside the coil. This is why you feel warm air coming off an air conditioning unit The cooling of the gas causes it to change into a liquid. The hot gas converts into a warm liquid, which is one of the unique properties of Freon. The warm liquid continues through the final portion of the coil and moves inside to the evaporator, which creates space for the liquid to expand. The liquid expands into a low-pressure gas, which is now cold. The cold gas goes through the "A" coil, which is inside the plenum of the heating system duct-work. The cold gas makes the coil cold. The cooling of the house occurs from drawing the warm house air across the coil. The velocity and volume of air across the coil dictates the temperature of the air on the other side of the coil. The techni- Around The House EVERETT RAWLINGS cian will set the fan speed so you get a 15-to 17-degree difference between the supply and return air. The cold gas moves through the coil and is pushed back into the suction line to the outside unit, which draws the cold gas back to the compressor and then the whole process starts again. In the heating mode, the compressor does the same thing. However, instead of pushing the hot gas to the outside coil, it pushes it to the inside coil. Once it gets into the inside coil, a similar process happens. Hot gas moves around the coil. The air from the house takes the heat off the coil, which is desirable, but while it does this, it drops the temperature of the gas. If it does this enough, the high pressure gas changes into a liquid. This continues through the coil, then through the expansion valve that allows the liquid to change to a low-pressure cold gas. This cold gas is taken to the outside coil the opposite of the AC modem, by moving gas and liquid the other way. Once it goes through the outside coil, it ends up back at the compressor and then the process starts again. In either mode, the compressor simply compresses the Freon gas. There is one more important point to remember when the system is in the heating mode and the cold gas comes to the outside coil. If the temperature is low enough, you may start to freeze the outside coil. When this happens, you will develop ice. When you start to form ice, the unit will automatically change to a defrost cycle. An outside thermostat controls this function. totalis i j fc u L zr-sJ but want to buy a home there. Jhelm Beach Ibst Does your chimney stack up? Most South Floridians use fireplaces as decorative pieces. But when the weather grows chilly and we get the occasional cold front, we do have an opportunity to light a fire.
