Typical air conditioning systems operate continuously until the room thermostat senses the desired temperature and turns the system off. As the room warms up again, the thermostat switches the air conditioner back on and the cycle repeats. |
The systems are dimensioned to cope with the extreme cooling demands of the FEW hottest days of the year. However, in most operational conditions, this maximum output is not required and the system is oversized. So running the system continuously until the room thermostat switches off means that the system operates with excess capacity most of the time. A typical cooling cycle with excess capacity looks like this: l --When the cycle starts, the compressor pushes cooling energy into the heat exchanger which ------acts as an energy storage. At this stage, the system works with high efficiency because ------compressors operate most efficiently when fully loaded. l --In normal weather conditions, the energy storage is soon fully "charged up". From this point -----onward, the compressor provides more cooling energy than the heat exchanger can take up -----(thermodynamic saturation). l --Running the compressor beyond this stage does not increase the cooling effect any -----more. It's just a WASTE of ENERGY....& MONEY! |

Basic Principle of AircoSaver Operation: 1. The AircoSaver is powered by the 24 volt supply from the control board. 2. The AircoSaver intercepts the signal wire from the thermostat to compressor. 3. The temperature sensor of the AircoSaver is installed in the coldest spot of the supply air. The AircoSaver DOES NOT interfere with the performance of the thermostat. When set point is reached, the thermostat still shuts down the entire system. Once the AircoSaver monitors three cycles, it determines how cold the supply air is capable of reaching. This indicates the evaporator is full and as cold as it will get. (thermodynamic saturation) The AircoSaver shuts off the compressor and allow the fan to continue running to pull the cold air into the plenum. When the temperature in the plenum begins to rise by 1.6 degrees, the AircoSaver releases the compressor to continue charging the system. If this release occurs in less than 3 minutes, the AircoSaver allows the compressor to run an additional one minute for up to ten additional minutes. This insures that short cycling does not occur while cooling parameters are maintained. If set point is reached at any time during this process, the whole system shuts down as it normally does. When the thermostat releases the system, the entire process starts over. |
