摘要: An injector for servicing a refrigerant system employs a reconfigurable container that is selectively configurable in a plurality of different container configurations. In each container configuration, an outlet of the reconfigurable container can be fluidly connected to the refrigerant system such that the injector can discharge treatment fluid through the outlet into the refrigerant system. The plurality of different container configurations can include a plurality of different fillable container configurations or one or more fillable container configurations and a pass-through configuration. In a fillable container configuration, the reconfigurable container defines a fillable space for receiving treatment fluid. In a pass-through container configuration, the reconfigurable container passes fluid from a disposable container through the outlet. In use, the desired container configuration is selected and fluid is injected from the injector into a refrigerant system.

摘要: A thermoelectric assembly includes a thermoelectric module having a hot side and a cold side, where a heat sink is coupled with the hot side of the thermoelectric module and a cold sink is coupled with the cold side of the thermoelectric module. A gasket is disposed between the heat sink and the cold sink and extends around a portion of the thermoelectric module. A vapor barrier is attached to and covers an outer surface of the gasket to prevent water vapor from penetrating the outer surface of the gasket.

摘要: A data center cooling system has an indoor portion wherein heat is absorbed from components in the data center, and an outdoor heat exchanger portion wherein outside air is used to cool a first heat transfer fluid (e.g., water) present in at least the outdoor heat exchanger portion of the cooling system during a first mode. When an appropriate time has been reached to switch from the first mode to a second mode, the outdoor heat exchanger portion of the data cooling system is switched to a second heat transfer fluid, which is a relatively low performance heat transfer fluid (compared to the first fluid). It has a second heat transfer fluid freezing point, lower than the first heat transfer fluid freezing point, and sufficiently low to operate without freezing when the outdoor air temperature drops below a first predetermined relationship with the first heat transfer fluid freezing point.

摘要: A system includes a compressor for increasing the pressure of a refrigerant; a condenser heat exchanger arranged downstream of the compressor for receiving a high pressure refrigerant output from the compressor and for transferring heat from the high pressure refrigerant to a source of water; an expansion device for reducing the pressure of a refrigerant; and an evaporator heat exchanger for extracting heat from ambient air. The evaporator heat exchanger includes a first tube bank having a first inlet arranged to receive a high pressure refrigerant output from the condenser and a first outlet fluidly coupled to the expansion device; and a second tube bank having a second inlet arranged to receive a low pressure refrigerant output from the expansion device, and a second outlet fluidly coupled to an inlet of the compressor.

摘要: In an embodiment, a method of preventing evaporator coil freeze in a heating, ventilation and air conditioning (HVAC) system includes determining a reference saturated suction temperate (SST) via a sensor disposed in relation to an evaporator coil in the HVAC system, where the HVAC system is operating in reheat dehumidification mode. The method also includes determining whether the reference SST is below a minimum SST threshold. The method also includes, responsive to a determination that the reference SST is below the minimum SST threshold, determining a decreased compressor speed. The method also includes modulating a variable-speed compressor in the HVAC system in correspondence to the decreased compressor speed.

摘要: A method of operating a refrigeration system. The method includes operating a multi-temperature refrigeration system that has a plurality of heat absorption heat exchangers in a single temperature mode. A number of the plurality of heat absorption heat exchangers are determined that require defrosting a single heat absorption heat exchanger is directed into a different operational state when the number of heat absorption heat exchangers that require defrosting is equal to one. E of the plurality of heat absorption heat exchangers is directed into a defrost mode when the number of heat absorption heat exchangers that requires defrosting is more than one.
