摘要： A heating, ventilation, air conditioning, and/or refrigeration (HVAC&R) system includes a first refrigerant circuit having a first evaporator configured to place a first refrigerant in a heat exchange relationship with a conditioning fluid, where the first evaporator includes a first set of first tubes and a second set of first tubes configured to direct the conditioning fluid through the first evaporator. The HVAC&R system also includes a second refrigerant circuit having a second evaporator configured to place a second refrigerant in a heat exchange relationship with the conditioning fluid, where the second evaporator includes a first set of second tubes and a second set of second tubes configured to direct the conditioning fluid through the second evaporator. The HVAC&R system further includes a conditioning fluid circuit configured to circulate the conditioning fluid serially through the first set of first tubes, the second set of first tubes, the first set of second tubes, and the second set of second tubes.

摘要： A condenser module of a heating, ventilation, and/or air conditioning (HVAC) system includes a first slab having a first plurality of tubes configured to receive a refrigerant from a compressor of the HVAC system. The first plurality of tubes is arrayed along a first dimension of the first slab. The condenser module also includes a second slab that has a second plurality of tubes configured to receive the refrigerant from the compressor. The second plurality of tubes is arrayed along a second dimension of the second slab, the second slab is oriented at an acute angle relative to the first slab, and the second dimension is greater than the first dimension.

摘要： The present application provides an evaporator, including a heat exchange tube set and a distribution device. The heat exchange tube set includes a plurality of heat exchange tubes. The distribution device is provided on one end of the length direction of the heat exchange tube set such that the distribution device can distribute a refrigerant through heat exchange tube inlets at the end portions of the plurality of heat exchange tubes. The distribution device includes a distribution device housing, at least one receiving port, and at least one distribution member. The receiving port is provided on the distribution device housing, and the distribution member is provided in the distribution device housing. The distribution device housing is disposed around the heat exchange tube inlets at the end portions of the heat exchange tube set and seals the heat exchange tube inlets. The distribution member can receive the refrigerant through the receiving port. The distribution member is provided with a plurality of distribution ports such that the refrigerant in the distribution member can be sprayed through the plurality of distribution ports towards the heat exchange tube inlets of the heat exchange tube set. The evaporator of the present application can uniformly distribute the refrigerant to the plurality of heat exchange tubes of the heat exchange tube set by using a simple structure, thereby effectively ensuring the heat exchange efficiency of the evaporator.
