Accompanying drawing explanation
Fig. 1 is the structural representation of air-conditioner outdoor unit one embodiment of the present utility model.
Realization, functional characteristics and the advantage of the utility model object, in connection with embodiment, are described further with reference to accompanying drawing.
The specific embodiment
Be described further with regard to the technical solution of the utility model below in conjunction with drawings and the specific embodiments.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
The utility model proposes a kind of air-conditioner outdoor unit.
With reference to Fig. 1, Fig. 1 is the structural representation of air-conditioner outdoor unit one embodiment of the present utility model.
In the utility model embodiment, this air-conditioner outdoor unit comprises compressor 10, cross valve 20, outdoor heat exchanger 30, gas-liquid separator 40 and heating branch road 50, and wherein compressor 10, cross valve 20, outdoor heat exchanger 30, indoor heat exchanger 60 and gas-liquid separator 40 form the loop of refrigerant.Output, the other end that one end of heating branch road 50 is connected to compressor 10 is connected to the input of gas-liquid separator 40.The bringing-up section 51 at these heating branch road 50 middle parts is connected to outdoor heat exchanger 30, and bringing-up section 51 housing preferred and outdoor heat exchanger 30 is fitted.
In the time that air-conditioner outdoor unit moves in lower environment, the refrigerant of the HTHP of sending from compressor 10 will directly be delivered to outdoor heat exchanger 30 by heating branch road 50, heat on chassis to outdoor heat exchanger 30, avoid frosting or accelerate to hold white speed, prevent the icing vicious circle that causes draining to have some setbacks in chassis, guarantee heating effect.
Based on above-described embodiment, the control module of flow control valve 70 and control flow control valve 70 opened/closed also can be set on heating branch road 50.Can pass through the opened/closed flow control valve 70 of control module automatic or manual, to realize conducting/blocking-up of controlling heating branch road 50.Making to heat branch road 50 needn't, in the state of normal open, avoid the waste of resource on the one hand; On the other hand as required automatic or manual remove opened/closed flow control valve 70, can make air-conditioning system hommization more, intellectuality.
In the above-described embodiments, this control module comprises the first controller 81, this first controller 81 is preferably temperature-sensing element, the temperature of the first controller 81 Real-Time Monitoring outdoor heat exchanger 30 environment of living in, when the temperature detecting is during lower than default lower limit, the first 81 of controllers control flow control valve 70 is opened, so that outdoor heat exchanger 30 is heated, prevent from freezing, until the temperature that the first controller 81 detects is during higher than preset upper limit value, the first 81 of controllers control flow control valve 70 cuts out.This control module is also for judging that whether air-conditioning system is in defrosting mode, if when air-conditioning system defrosts, whether the temperature of outdoor heat exchanger 30 environment of living in all will control flow control valve 70 lower than default lower limit is opened, and to accelerate defrosting, shortens the defrosting time.
