摘要: The disclosed technology includes devices, systems, and methods for heat pump systems configured to operate in low ambient temperatures. The disclosed technology can include a heat pump water heater system having an evaporator, a first compressor configured to compress refrigerant to a first pressure, and a second compressor configured to compress the refrigerant to a second pressure. The second pressure can be greater than the first pressure. The heat pump water heater system can include a preheater configured to receive the refrigerant at the first pressure and heat water and a condenser configured to receive the refrigerant at the second pressure and heat water. The water can be passed through the preheater before being passed through the condenser.

摘要: Described is a cooling system comprising a compressor (31), a condenser (32) and at least a first evaporator (34) and a second evaporator (35) connected in parallel with the first evaporator. A refrigerant is circulated in the cooling system. Further a controller (40) is provided and configured to control the flow of refrigerant to and/ or from at least one of said first evaporator and second evaporator based on the superheat of said at least one of the first evaporator and second evaporator. Hereby a control algorithm that is stable and at the same time enables fast switching in the refrigerant flow is achieved.

摘要: The present invention provides a system and method for an improved multistage, cascade refrigeration system using hot gas defrost to rid the evaporator of ice build-up which accumulates over time, while the air in the evaporator enclosure remains below the freezing point of water. The present invention thus provides greater defrost flexibility with increased ease of design and implementation than current refrigeration systems, which allows for more robust hot gas defrost function for multistage refrigeration systems, such that it is unaffected by temperature changes of the condensing fluid (ambient air temperature for air cooled condensers, water temperature for water cooled condensers), and can be readily adapted to any refrigerant suitable for a selected temperature range.
