The realization of the utility model purpose, functional characteristics and advantage are described further with reference to accompanying drawing in connection with embodiment.
The specific embodiment
Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
With reference to Fig. 1, Fig. 1 is the structural representation of the utility model air-conditioner outdoor unit preferred embodiment.The kind air-conditioner outdoor unit that present embodiment provides comprises compressor 10, cross valve 20 and controller (not shown), wherein compressor 10 is provided with air inlet pipe 101 and the blast pipe 102 that is connected with cross valve 20, be provided with the low pressure sensor 1011 for detection of its intraductal atmospheric pressure in this air inlet pipe 101, be provided with the high pressure sensor 1021 for detection of its intraductal atmospheric pressure in the blast pipe 102; Controller is electrically connected with low pressure sensor 1011, high pressure sensor 1021 and cross valve 20 respectively, to control the duty of this cross valve 20.
In the present embodiment, air-conditioner outdoor unit also comprises outdoor heat exchanger 30 and electric expansion valve 40, and indoor apparatus of air conditioner comprises indoor heat exchanger.Above-mentioned cross valve 20 has exhaust end D, suction end S, condenser end C and evaporator end E.Wherein exhaust end D is connected with above-mentioned blast pipe 102, suction end S is connected with above-mentioned air inlet pipe 101, condenser end C be connected with the air inlet of indoor heat exchanger and the air inlet of condenser end C and indoor heat exchanger between be connected with outdoor heat exchanger 30, be connected with electric expansion valve 40 between the air inlet of this outdoor heat exchanger 30 and indoor heat exchanger, evaporator end E is connected with the gas outlet of indoor heat exchanger.
Above-mentioned controller and low pressure sensor 1011, high pressure sensor 1021 and cross valve 20 electrical connections.During work, detect the intraductal atmospheric pressure intensity of air inlet pipe by low pressure sensor 1011, and this air pressure intensity is sent to controller, detected simultaneously the intraductal atmospheric pressure intensity of blast pipes 102 by high pressure sensor 1021, and this air pressure intensity is sent to controller.The connection status of the Data Control cross valve 20 that this control sends according to low pressure sensor 1011 and high pressure sensor 1021 namely commutates to cross valve 20.
For example, when refrigeration, by controller control cross valve 20 no powers, then the exhaust end D of cross valve and condenser end C are communicated with, and suction end S and evaporator end E are communicated with.Refrigerant will change by compressor 10 gas of HTHP into this moment, flow to exhaust end D, the condenser end C of cross valve 20 through blast pipe 102, then enter outdoor heat exchanger 30, refrigerant carries out becoming after the heat exchange liquid of middle temperature high pressure in outdoor heat exchanger 30, through behind the electric expansion valve 40, become the liquid of low-temp low-pressure; Become the gas of low-temp low-pressure after this liquid inflow indoor heat exchanger heat exchange, pass through again the evaporator end E of cross valve 20, and Self inhaling end S returns compressor 10 from air inlet pipe 101.
When heating, judged when the air pressure difference between blast pipe 102 and the air inlet pipe 101 during greater than the threshold value of controller by controller, powered on by control cross valve 20, thereby realize commutating, this moment, exhaust end D and the evaporator end E of cross valve 20 were communicated with, and suction end S and condenser end C are communicated with.Refrigerant will change by compressor 10 gas of HTHP into this moment, flow to exhaust end D, the evaporator end E of cross valve through blast pipe 102, then enter indoor heat exchanger, refrigerant carries out becoming after the heat exchange liquid of middle temperature high pressure in indoor heat exchanger, through behind the electric expansion valve 40, become the liquid of low-temp low-pressure; Become the gas of low-temp low-pressure after this liquid inflow outdoor heat exchanger heat exchange, pass through again the condenser end C of cross valve 20, and Self inhaling end S returns compressor 10 from air inlet pipe 101.
Should be noted that the threshold value of above-mentioned controller, can arrange according to actual conditions, can realize commutation as long as can be able to guarantee cross valve 20, be not further qualified at this.For reducing noise, this threshold value is the smaller the better.
The utility model is by at the air inlet pipe 101 interior low pressure sensors 1011 that arrange, the blast pipe 102 interior high pressure sensors 1021 that arrange, and calculate the difference of the air pressure that low pressure sensor 1011 and high pressure sensor 1021 send and the size between the threshold value in the controller by controller, cross valve 20 is carried out switch operation.Therefore, the utility model arranges the threshold value of controller according to the minimum movements pressure reduction of cross valve 20, thereby the draught head of air inlet pipe 101 and blast pipe 102 in the time of can suitably reducing cross valve 20 commutation, and then reduce the noise that produces when cross valve 20 commutates, more be suitable for the user and use.
