Abstract: A method and apparatus for determining the sufficiency of refrigerant charge in an air conditioning system by the use of only two temperature measurements. The temperature of the liquid refrigerant leaving the condenser coil is sensed and the temperature of the condenser coil itself is sensed and the difference between these two measurements is calculated to provide an indication of the adequacy of refrigerant charge in the system. This process is refined by steps taken to eliminate measurements during transient operations and by filtering signals to eliminate undesirable noise. A permitted threshold of deviation is calculated by using probability theory.

Abstract: In a residential furnace having a layered insulation material on the inner walls of the heat exchanger compartment, the inner aluminum foil layer has a plurality of holes formed therein in order to allow for the outer layer to absorb the sound within the heat exchanger compartment and thereby reduce the noise emanating from the furnace. Both the density and size of the holes are optimized to maximize the sound absorption performance over the particular frequency ranges that are characteristic of the furnace.

Abstract: The efficiency of a vapor compression system is increased by coupling the evaporator with either the intercooler of a two-stage vapor compression system or the compressor component. The refrigerant in the evaporator accepts heat from the compressor component or the refrigerant in the intercooler, heating the evaporator refrigerant. As pressure is directly related temperature, the low side pressure of the system increases, decreasing compressor work and increasing system efficiency. Additionally, as the heat from the compressor component or from the refrigerant in the intercooler is rejected to the refrigerant in the evaporator, the compressor is cooled, increasing the density and the mass flow rate of the refrigerant to further increase system efficiency.
