Change the duration of time slot during ring.
In the first variant of garment drying apparatus 1, heat pump 11 includes open pipe 14 to 17.Working fluid in order to prevent
F is flowed when AC rotary compressor 12 disconnects to balance pressure, AC rotary compressor 12 be implemented to so that, disconnect shape
Under state, high-pressure side and its low-pressure side hermetically seal each other.Therefore, the AC rotary compressor 12 of disconnection prevents working fluid
F flows to its low-pressure side from its high-pressure side.Additionally or alternatively, expansion device 13 can be by control unit 18 in opening state
It is optionally switched between closed state, and control unit 18 is suitable for opening expansion when AC rotary compressor 12 is connected
Device 13 simultaneously closes expansion device 13 when AC rotary compressor 12 disconnects.Therefore, expansion device 13 prevent working fluid F from
Its high-pressure side flows to its low-pressure side.
In the second variant of garment drying apparatus 1, garment drying apparatus 1 includes being connected to can control for control unit 18
The first disconnecting device 19, the first disconnecting device 19 is between expansion device 13 and evaporator 6.The control of control unit 18 first
Disconnecting device 19, so that it is opened when AC rotary compressor 12 is connected, and when AC rotary compressor 12 is followed in drying
It is closed when disconnecting during ring.If the high-pressure side of AC rotary compressor 12 and low-pressure side are in the off state each other hermetically
Sealing, but expansion device 13 be it is not closable, i.e., open always, then the variant may be particularly advantageous.Alternatively,
Controllable first disconnecting device 19 can be between condenser 9 and expansion device 13.
In the third variant of garment drying apparatus 1, garment drying apparatus 1 also comprise be connected to control unit 18 can
The second disconnecting device 20 or controllable third disconnecting device 21 of control.Second disconnecting device 20 is located at evaporator 6 and AC revolves
Between the low-pressure side of rotary compressor 12.Third disconnecting device 21 is located at high-pressure side and the condenser 9 of AC rotary compressor 12
Between.Control unit 18 controls the second disconnecting device 20 or third disconnecting device 21, so that when AC rotary compressor 12 is connected
When it open, and when AC rotary compressor 12 disconnects during drying cycles it close.If AC rotary compressor
12 high-pressure side and low-pressure side be in the off state communicate with each other and expansion device 13 be not closable, the then variant
It may be particularly advantageous.
In the 4th variant of garment drying apparatus 1, garment drying apparatus 1 include controllable first disconnecting device 19,
Controllable second disconnecting device 20 and controllable third disconnecting device 21.For example, if the high pressure of AC rotary compressor 12
Side and low-pressure side be in the off state communicate with each other and expansion device 13 be it is not closable, then the variant is especially reliable
Ground prevents working fluid mobile during the off-state of AC rotary compressor 12.
Certainly, the present invention is not limited to described embodiments.
For example, garment drying apparatus 1 can not have cotton linters filter 4.
In addition, garment drying apparatus 1 may include the additional fan for cooling down AC rotary compressor 12.
