State second outlet end 128.The desuperheater heat exchanger outlet can be run into by leaving the refrigerant at the second outlet end 128
129 and the node at the main-inlet end 136 of the reversal valve 122.Because the HVAC system 100 can be configured as in heating mode
Operation, refrigerant can not enter the first exit end 125 of the triple valve 126, therefore not handed over by desuperheater heat
Parallel operation goes out 129 and enters the desuperheater heat exchanger 124.Accordingly, the desuperheater heat exchanger 124 is from cold-producing medium stream
Body loop is removed efficiently.
As when the HVAC system 100 is run in heating mode heat drop is crossed from the removal of cold-producing medium stream body loop is described
The result of warm device heat exchanger 124, the desuperheater heat exchanger 124 functionally leave unused relative to cold-producing medium stream.However, should
Desuperheater heat exchanger 124 can be configured to isolate unwanted excess liquid refrigeration during the heating operation of HVAC system 100
Agent.Therefore, the desuperheater heat exchanger 124 can perform the work(of a traditional filling trap in heating mode
Can, isolate the excessive liquid for being deposited in the indoor heat converter 108 and reducing the efficiency of HVAC system 100 traditionally
State refrigerant.In addition, the result positioned as desuperheater heat exchanger described in refrigerating circuit 124, the desuperheater

The excess liquid refrigerant that compressor 116 there may be potential risk enters the compressor 116, so as to improve the compressor
116 reliability and/or prevent from damaging the compressor 116.
In addition, by positioning the desuperheater heat exchanger 124 in the high-pressure side of the reversal valve 122, this is skimmed over
The air of desuperheater heat exchanger 124 is likely lower than saturation temperature, and it can be by the desuperheater heat exchanger 124
Refrigerant is condensed into liquid refrigerant.So, by removing the hot cooler heat exchanger 124 from cold-producing medium stream body loop,
The liquid refrigerant that may be condensed in the desuperheater heat exchanger 124 can be further from the indoor heat converter 108
And/or the compressor 116 is isolated.In addition, except when the HVAC system 100 can improve when being run in refrigerating mode
Outside the cooling performance and/or efficiency of HVAC system 100, the desuperheater heat exchanger 124 and/or the DSHCR systems
System 106 can improve heating properties, by performing the function of traditional filling trap, isolate unnecessary liquid refrigerant without
Need to increase extra-pay and increase tradition fills the complexity of retention system.
Refrigerant leaves the triple valve 126 by the second outlet end 128, therefore can pass through the main-inlet end
136 enter the reversal valve 122.In heating mode configuration, during the HVAC system 100 is run in refrigerating mode, institute
State reversal valve 122 and can selectively be configured be transferred into the refrigerant at the main-inlet end 136 to it is described second variable
Relative first variable port 130 in port 134.Refrigerant can leave the commutation by first convertible tip 130
Valve 122 and the inflow indoor heat converter 108.First convertible tip 130 and the interior are entered by transfering fluid
Heat exchanger 108 is prior to entering the outdoor heat converter 114, it is to be understood that passes through the refrigeration of the HVAC system 100
Agent stream is effectively reversed.
High temperature refrigerant may then flow to the indoor heat converter 108, and it can contact the heat to and pass through herein
And/or contact the air-flow of the indoor heat converter 108.After leaving the indoor heat converter 108, refrigerant can flow through
And/or around the indoor measurement apparatus 112, therefore cold-producing medium stream is not limited substantially by the indoor measurement apparatus 112.
Refrigerant is generally away from the indoor measurement apparatus 112, flows into the outdoor measurement apparatus 120, it can be measured by the room
The cold-producing medium stream of outer metering device 120, because the refrigerant in the outdoor downstream of measurement apparatus 120 compares the outdoor measurement apparatus
The refrigerant of 120 upstream sides is in a relatively low pressure.Come out from the outdoor measurement apparatus 120, refrigerant can enter described
Outdoor heat converter 114.When cold-producing medium stream can lead to through the outdoor heat converter 114, heat from by the outdoor fan 118
The air-flow for crossing and/or contacting the outdoor heat converter 114 passes to refrigerant.Refrigerant leaves the outdoor heat converter 114
The second convertible tip 134 of the reversal valve 122 can be entered, the wherein reversal valve 122 can be configured selectively that will freeze
