Exemplary embodiments provide a flexible cooling blanket including a cooling layer assembly and a heat dissipating layer assembly.

A noise reduction device for reducing noise in refrigeration equipment includes at least one transition tube having a diameter gradually increasing from a capillary of the refrigeration equipment to an evaporator of the refrigeration equipment. The refrigerant liquid is circulated through the noise reduction device.

An accumulator and oil separator device includes a housing having a cavity, an oil separator unit disposed in the cavity and designed to separate oil from a refrigerant and oil mix received from a compressor and to output the oil into the cavity. The accumulator and oil separator device further includes an accumulator inlet tube to carry a received refrigerant into the cavity. The accumulator and oil separator device also includes an accumulator outlet tube to output the received refrigerant and the oil from the cavity.

An apparatus includes a high side heat exchanger, a second heat exchanger, a load, a variable speed compressor, and a three-way valve. The high side heat exchanger removes heat from a refrigerant. The second heat exchanger removes heat from the refrigerant. The load uses the refrigerant to remove heat from a space proximate the load. The variable speed compressor compresses the refrigerant from the load and directs the compressed refrigerant to the high side heat exchanger. The three-way valve, when operating in a first mode, directs the refrigerant from the high side heat exchanger to the load and when operating in a second mode, directs the refrigerant from the high side heat exchanger to the second heat exchanger.

A predictive failure system for a cooling apparatus having sensors measuring operational components of a cooling apparatus to determine performance data and means to analyze the data to determine a performance profile, wherein anomalies in the performance profile are determined and the operator of the cooling apparatus is warned prior to failure of the operational components.

The present disclosure relates to a refrigeration circuit that includes a controller communicatively coupled to a compressor, an expansion valve, and a sensor of the refrigeration circuit. The controller may activate the compressor and actuate the expansion valve such that the compressor is active while the expansion valve is closed. The controller may also measure a pressure of a refrigerant in the refrigeration circuit using the sensor while the compressor is active and the expansion valve is closed. Additionally, the controller may determine whether a refrigerant leak exists based on a maximum measurement time being reached or a time difference between a first time associated with the compressor being active while the expansion valve is closed and a second time associated with the measured pressure falling below a threshold value.

A heat pump system includes a refrigerant circuit comprising a compressor, a reversing valve, a first heat exchanger, a second heat exchanger, a reheat heat exchanger, and a three-way valve. The reversing valve is configured to receive refrigerant from the compressor and adjust between a first configuration to direct the refrigerant toward the three-way valve and a second configuration to direct the refrigerant toward the first heat exchanger. The three-way valve is configured to adjust between a first position to direct the refrigerant between the reversing valve and the second heat exchanger and a second position to direct the refrigerant from the reversing valve to the reheat heat exchanger.
