摘要： A five element refrigeration system whereby heating and cooling functions of the system can be accomplished as in a reverse cycle system without needing to reverse the flow of the liquid through the system. The system comprises a refrigerant compressor, a pair of air side heat exchangers, an air blower to provide circulation for the air side heat exchangers, a pair of water side heat exchangers, and a reservoir to provide cooling water for the water side heat exchangers. The refrigerant compressor increases the pressure of a refrigerant flowing through it, causing it to circulate through the first air side heat exchanger, or a reheat coil. The refrigerant continues to the first water side heat exchanger, which acts as a condenser. In a cooling mode, the refrigerant continues to the second air side heat exchanger, which acts as an evaporator. In a heating mode, the refrigerant continues to the second water side heat exchanger, which acts as an evaporator. The reservoir water leaving the first water side exchanger is preheated when entering the second water side exchanger. The increase in the water temperature increases the efficiency of the system. Various valves are employed so that any or all of the heat exchangers may be bypassed in the operation of the system.

摘要： A system and method of controlling a multiple condenser air conditioning system that provides for efficient regulation of air temperature. The refrigeration system includes one or more valves whose operation is preferably controlled by programmable control logic to regulate flow through the refrigerant condenser(s) and sequentially control compressor discharge pressure and temperature in response to demands for heating or reheating of a supply air flow.

摘要： A heat pump system that can be selectively utilized to discharge excessive heating and cooling capacity toward secondary devices of the system to maintain operation of the heat pump system to better manage the respective temperatures associated with the fluid flows in a manner that reduces the need for cycling the heat pump system ON and OFF to attain desired fluid output temperature manipulations.

摘要： Precise control of the temperatures of leaving air in an air conditioning system and of leaving water in a water heating system are obtained with a throttling valve whose flow rate is modulated with an electric signal. The high pressure outlet of a refrigerant compressor is coupled jointly to the inlet of the valve and to the refrigerant inlet of a first condenser and the outlet of the valve is coupled jointly to the refrigerant outlet of the first condenser and to the refrigerant inlet of a second condenser. A programmable controller receives input signals corresponding to one or more entering media characteristics, such as dry bulb temperature, dew point temperature, and percent humidity and produces control signals that modulate the valve flow rate to thereby maintain the leaving air or water temperature at a specified set point with high precision.

摘要： A dehumidifying system includes an enclosure having at least one opening disposed at a first end and at least one opening disposed at a second end. A plurality of air paths that extend through the enclosure and are separated from one another by partitions along at least a portion of the enclosure. A dehumidifier evaporator is disposed within the enclosure and configured such that at least one of the air paths is disposed to flow through the dehumidifier evaporator. The dehumidifier evaporator includes a dehumidifying coil and a heat pipe assembly at least partially wrapping around the dehumidification coil.
