摘要： In a heat pump system designed for use with a relatively low pressure refrigerant, provision is made, by use of a vapor pressure control system, to use a higher pressure refrigerant without replacement of the indoor coil and the line set. The vapor pressure is sensed during periods of heat pump operation, and when the pressure reaches a predetermined maximum threshold level, the outdoor fan speed is reduced to thereby cause the vapor pressure to be reduced. When the vapor pressure is reduced to a predetermined minimum threshold level, then the fan speed is resumed so as thereby allow the vapor pressure to again be increased.

摘要： A reversible heat pump provides multiple heating and cooling modes and includes a compressor, an evaporator and heat exchanger all interconnected and charged with refrigerant fluid. The heat exchanger includes tanks connected in series to the water supply and a condenser feed line with heat transfer sections connected in counterflow relationship. The heat pump has an accumulator and suction line for the refrigerant fluid upstream of the compressor. Sub-cool transfer tubes associated with the accumulator/suction line reclaim a portion of the heat from the heat exchanger. A reversing valve switches between heating/cooling modes. A first bypass is operative to direct the refrigerant fluid around the sub-cool transfer tubes in the space cooling only mode and during which an expansion valve is utilized upstream of the evaporator/indoor coil. A second bypass is provided around the expansion valve. A programmable microprocessor activates the first bypass in the cooling only mode and deactivates the second bypass, and vice-versa in the multiple heating modes for said heat exchanger. In the heating modes, the evaporator may include an auxiliary outdoor coil for direct supplemental heat dissipation into ambient air. In the multiple heating modes, the condensed refrigerant fluid is regulated by a flow control valve.

摘要： A refrigeration cycle of an air conditioner includes a variable-capacity compressor which has a predetermined maximum capacity. A thermal storage tank filled with a regenerative material is connected between the discharge side of the compressor and an indoor heat exchanger. In a regenerating operation of the refrigeration cycle, the regenerative material deprives the heat of a refrigerant discharged from the compressor and stores it. At this time, the compressor is driven within a capacity range having a maximum value lower than the predetermined maximum capacity, and an indoor fan for delivering air to the indoor heat exchanger is stopped.

摘要： A microprocessor based heat pump control apparatus having a user-operated system console and a system function controller is provided in which normal operating target temperature settings are automatically converted to an expanded operating temperature range (standby operating mode), having preset upper and lower target temperature settings, in response to predetermined operating conditions within the system. The system function controller is preprogrammed to respond to a predetermined number of invalid data signal communications emanating from the user-operated console to switch into the standby operating mode. Provision is made for the user to insert a standby mode instruction at the user-operated console. Provision is also made for the system controller to enter standby during a power-up sequence when invalid user-inserted volatile data is sensed from storage means used to retain the volatile data during the power-off time period.

摘要： Modular heating and cooling systems may include one or more modules connected to a fluid input and fluid output. Conventional modular heating and cooling systems typically use a single fluid in the cooling, heating and source fluid loops due to the mixing of fluids in the system. According to an aspect there is provided a modular heating system comprising at least one heating and cooling apparatus. The apparatus comprises a first heat exchanger, a second heat exchanger and a third heat exchanger. The apparatus further comprises a refrigerant line system coupled to the first (e.g. cooling), second (e.g. heating) and third (e.g. source) heat exchangers and configurable for selectively directing refrigerant fluid through the heat exchanger to provide multiple modes of operation. The heating, cooling and source fluid loops may be separate and independent such that the fluids do not mix.

摘要： Systems and methods for controlled subcooling of working fluid in a heating, ventilation, air conditioning and refrigeration (HVACR) system through a suction line heat exchanger are disclosed. The suction line heat exchanger may receive a first fluid flow travelling to a suction of the compressor in the HVACR system and second flow of working fluid that is travelling from a heat exchanger receiving the discharge of the compressor to an expansion device. Superheating of the first working fluid may be determined based on temperature measurements prior to and following the suction line heat exchanger. The superheating may be used to control the quantity of the second flow of working fluid introduced into the suction line heat exchanger, for example to maintain superheat that is below a threshold value. These systems may include chillers and heat pump systems, and methods may be applied to chillers or heat pump systems.
