Description
Technical field
The utility model belongs to air-conditioning technical field, relates in particular to a kind of air conditioner with defrosting anti-frosting function.
Background technology
When air-conditioning carries out low-temperature heating in the winter time, condenser can produce frost, affects the heating effect of air-conditioning.When adopting shutdown refrigeration modes to dissolve the frosting on condenser, affect corresponding indoor temperature.This Defrost mode can not meet the requirement that user warms oneself winter.
At present, the Defrost mode that air-conditioning adopts is mostly, after shutting down, cross valve is commutated to refrigerating operaton state, and indoor and outdoor machine blower fan is out of service simultaneously.By the temperature of heating operation certain hour sensing chamber's outer sensor or interior sensor, judge whether condenser needs defrosting.When condenser need to defrost, after shutting down, control cross valve commutation, forward refrigerating operaton to, indoor and outdoor machine blower fan stops simultaneously.In defrosting during this period of time, air-conditioning stops heating operation.This Defrost mode can affect the heating effect of air-conditioning.
Utility model content
The purpose of this utility model is: for the deficiencies in the prior art, and provide a kind of have defrosting anti-frosting function air conditioner, this air conditioner utilizes condensation heat defrosting and the frost prevention of condensation waste heat, has guaranteed the effect in the defrosting frost prevention of extremely low temperature environment (at as-30 ~-20 ℃) changes in temperature unit.
For achieving the above object, the utility model adopts following technical scheme: the air conditioner with defrosting anti-frosting function, comprise compressor, condenser, evaporimeter, cross valve, gas-liquid separator and circulating pump, described circulating pump is connected with described condenser, one end of described condenser is communicated with one end of described evaporimeter by described cross valve, the other end of described condenser is communicated with the other end of described evaporimeter by a loop, in described loop, be provided with condensation residual evaporator, described compressor is communicated with described gas-liquid separator by described cross valve.
As a kind of improvement with the air conditioner of defrosting anti-frosting function described in the utility model, described loop is also provided with check valve and throttling arrangement, the quantity of described check valve is set to a plurality of, a plurality of described check valves are arranged on the pipeline in loop, and described throttling arrangement is positioned at the output of described condensation residual evaporator.
As a kind of improvement with the air conditioner of defrosting anti-frosting function described in the utility model, described condenser is provided with cold/hot water import and cold/hot water outlet.
As a kind of improvement with the air conditioner of defrosting anti-frosting function described in the utility model, described evaporimeter is provided with evaporator fan.
The beneficial effects of the utility model are: the utility model comprises compressor, condenser, evaporimeter, cross valve, gas-liquid separator and circulating pump, circulating pump is connected with condenser, one end of condenser is communicated with one end of evaporimeter by cross valve, the other end of condenser is communicated with the other end of evaporimeter by a loop, in loop, be provided with condensation residual evaporator, compressor is communicated with gas-liquid separator by cross valve.The utility model utilizes condensation heat defrosting and the frost prevention of condensation waste heat, has guaranteed the effect in the defrosting frost prevention of extremely low temperature environment (at as-30 ~-20 ℃) changes in temperature unit.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with the specific embodiment and Figure of description, the utility model is described in further detail, but embodiment of the present utility model is not limited to this.
As shown in Figure 1, the air conditioner with defrosting anti-frosting function, comprise compressor 1, condenser 2, evaporimeter 3, cross valve 4, gas-liquid separator 5 and circulating pump 6, circulating pump 6 is connected with condenser 2, one end of condenser 2 is communicated with one end of evaporimeter 3 by cross valve 4, and evaporimeter 3 is provided with evaporator fan 7, and after defrosting, evaporator fan 7 is opened in advance, circulating pump 6 and cross valve 4 move simultaneously, and unit moves normally.The other end of condenser 2 is communicated with the other end of evaporimeter 3 by a loop, is provided with condensation residual evaporator 8 in loop, and in summer, condensation residual evaporator 8 can be so that condensation of the present utility model be more abundant; In the winter time, utilize the middle temperature of condensation residual evaporator 8, in the defrosting water while guaranteeing Defrost operation and unit running process, the water of evaporimeter 3 bottoms cannot be freezing, all drains.Compressor 1 is communicated with gas-liquid separator 5 by cross valve 4, from the requirement of gas-liquid separator 5, just requires it can gas is separated as far as possible with liquid, through after gas-liquid separator 5, liquid is exactly liquid, does not contain gas, and gas is exactly gas, do not contain liquid.Described loop is also provided with check valve 11 and throttling arrangement 12, the quantity of check valve 11 is set to a plurality of, a plurality of check valves 11 are arranged on the pipeline in loop, throttling arrangement 12 is positioned at the output of condensation residual evaporator 8, fluid will form local contraction in throttling place, thereby flow velocity is increased, and static pressure reduces, so it is poor to produce static pressure in the front and back of throttling arrangement 12.
Preferably, condenser 2 is provided with cold/hot water import 9 and cold/hot water outlet 10, and condenser 2 can be passed to atmosphere by the gaseous refrigerant heat of HTHP, and the refrigerant gas that discharges heat of gasification condenses into liquid, then by cold/hot water, exports 10 and flows out.
When unit judgement must be carried out defrost, compressor 1 and circulating pump 6 turn round always, evaporator fan 7 shuts down, cross valve 4 is opened, the hot gas that compressor 1 is discharged becomes original evaporimeter 3 into condenser 2 by turning to of cross valve 4 and defrosts, and the water that during the residual evaporator of condensation simultaneously 8 keeps, temperature produces defrost discharges smoothly.
The announcement of book and instruction according to the above description, the utility model those skilled in the art can also change and revise above-mentioned embodiment.Therefore, the utility model is not limited to the above-mentioned specific embodiment, and any apparent improvement, replacement or modification that every those skilled in the art have done on basis of the present utility model all belong to protection domain of the present utility model.In addition,, although used some specific terms in this description, these terms just for convenience of description, do not form any restriction to the utility model.
