摘要： A dual (or multi) sectional evaporator system comprising first and second (or more) evaporator sections capable of cooling the air supply through the evaporator. The first evaporator section is positioned upstream of the second evaporator section (second upstream of the third and so on). However, the warmest refrigerant passes through the first evaporator section and the coldest refrigerant passes through the second evaporator section (or last evaporator section if more than two sections), such that the air supply is precooled prior to reaching the second (or last) evaporator. Providing a two (or more) passes of refrigerant through the dual (or multi) sectional evaporator system increases the superheat temperature out of the first evaporator up to about 25 degrees Fahrenheit, and/or increases the mass flow of refrigerant because of the increased heat exchange efficiency provided by counterflow heat exchange. Moreover, in the preferred embodiment for an A-coil or slant coil, the second evaporator section is positioned over the top of the first evaporator section such that the second evaporator overlays the first evaporator section in order to maximize the use of available space. Also, A-coil or slant coil forms of the present invention are configured such that they include contoured cut-out shaped corner portions wherein the squared corners of the evaporators are substantially eliminated thereby eliminating the dead air flow spaces typically associated with other known evaporators. The elimination of the dead air space allows the system to operate at a lower fan speed as well as allows the system to be constructed and operate within smaller confines.

摘要： First, a system for providing liquid refrigerant subcooling, subsequent to that subcooling accomplished by the primary condenser of an air conditioner or heat pump, by means of evaporative cooling utilizing the condensate water of said air conditioner or heat pump system and/or some other water supply to wet the surface of the subcool heat exchanger and then passing the cold, dry building exhaust air required for good indoor air quality across the wetted surface of the subcool heat exchanger. Said exhaust air could be used after first undergoing a sensible heat exchange with the incoming make up air. Said subcooling providing for an increased refrigeration capacity, and efficiency of the system.Secondly, a system for providing hot gas discharge refrigerant precooling before said hot gas passes into the primary condenser of an air conditioner or heat pump, by means of evaporative cooling utilizing the condensate water of said air conditioner or heat pump system and/or some other water supply to wet the surface of the precool heat exchanger and then passing the cold, dry building exhaust air required for good indoor air quality across the wetted surface of the precool heat exchanger. Said precooler providing lower power consumption of the compressor, lower head pressure, increased mass flow of the refrigerant and improved efficiency of the primary condenser of the air conditioning or heat pump system.Said exhaust air could be used after first undergoing a sensible heat exchange with the incoming make up air on either the subcooler or precooler.Finally, a combination subcooler and precooler system where the cold dry exhaust air is first used to evaporatively subcool the liquid refrigerant in the water wetted subcooler and then subsequently used to conductively cool the hot gas refrigerant passing through a dry surface precooler or alternately used to evaporatively cool the wetted surface of the precooler thereby evaporatively precooling the hot gas refrigerant passing through the precooler.

摘要： The apparatus of the invention includes a precooler (post heater) heat exchanger and a subcooler heat exchanger which are connected in fluid communication with the refrigerant input and output, respectively, of the condenser (evaporator) of a heat transfer system. A fluid, such as water, is forced through the subcooler heat exchanger and then through the precooler (post heater) heat exchanger to be in a heat exchanging relationship with the refrigerant flowing therethrough.The method of the invention includes the step of regulating the flow rate of the water flowing through the apparatus such that the refrigerant is precooled to approximately its saturated-vapor state and subcooled when the system is operating in a cooling mode and such that the refrigerant is post heated to at least a saturated-vapor state and subcooled when the system is operating in a heating mode.

摘要： In a refrigeration system, a multiple compressor system for maintaining the heat output constant while the outside ambient temperature continues to decrease. The present invention comprises of a primary compressor and at least one secondary compressor. The entire refrigeration system is sized for the primary compressor operating while in the cooling mode. In the heating mode, the primary compressor operates by itself until the outside ambient temperature falls to a temperature within a particular range. Once the predetermined temperature set point is met, a secondary compressor begins operating in conjunction with the primary compressor such that the mass flow of refrigerant through the system in the heating mode of operation is no greater than that of the primary compressor operating alone in the cooling mode. While the outside temperature continues to decrease, additional secondary compressors may be included to maintain a constant heat output. In the cooling mode, only a single compressor is required to operate the system. Each of the compressors may alternate with any other so that the lives of the compressors are preserved.
