    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.
