    Abstract: 一种基于压热效应的室温压卡制冷机包括高精密高压电动注射泵(1)、压卡元件(2)、换热流体、冷端换热器(3)和热端换热器(4),通过压卡工质在高精密高压电动注射泵(1)的作用下会由于相变产生加压放热和卸压吸热现象,换热流体在压卡制冷工质间往复流动而交换热量和冷量。高精密高压电动注射泵(1)为压卡制冷循环提供压力,压力恒定输出。加压形式为液体压力,加压用油同时作为换热流体,将压力驱动的热量与冷量直接带入热端换热器(4)、冷端换热器(3)中完成循环。

    Abstract: A pumped refrigerant system can include a condenser, a pump coupled downstream of the condenser, an evaporator assembly coupled downstream of the pump, the condenser being coupled downstream of the evaporator assembly, and a refrigerant heating assembly coupled downstream of the pump, the condenser being coupled downstream of the refrigerant heating assembly. The refrigerant heating assembly can include a tank and a heating element coupled to the tank and configured to heat refrigerant within the tank. An input valve can be configured to selectively allow the pump to push refrigerant into the tank. An output valve can be configured to selectively inject heated refrigerant from the tank into plumbing upstream of the condenser.

    Abstract: A refrigeration system of a building includes: a compressor module configured to, in response to a determination that an amount of a refrigerant of the refrigeration system that is present outside of the refrigeration system and within the building is greater than a first predetermined amount, maintain a compressor off continuously for a predetermined period; and a fan module configured to, in response to the determination, maintain a fan on continuously for at least the predetermined period, and where the compressor module is further configured to, without receiving input indicative of a reset of the refrigeration system, after the compressor has been off for the predetermined period and the amount of refrigerant that is present outside of the refrigeration system within the building is less than a second predetermined amount, selectively turn the compressor on.

    Abstract: A system for detecting and mitigating a refrigerant leak includes a temperature control device configured to transmit control signals to a component controller and a blower configured to circulate air. The system includes a leak mitigation controller electrically coupled to the temperature control device and the component controller. The leak mitigation controller directs incoming power to the temperature control device. The leak mitigation controller includes a sensor configured to measure a refrigerant concentration and a relay configured to selectively: (i) connect the temperature control device to the incoming power or (ii) connect the blower to the incoming power. The leak mitigation controller is configured to measure the refrigerant concentration with the sensor and, in response to the measured refrigerant concentration exceeding a threshold, actuate the relay to connect the blower to the incoming power.
