Abstract
The utility model discloses a capillary assembly capable of preventing an outdoor heat exchanger of an air conditioner from frosting. The capillary assembly capable of preventing the outdoor heat exchanger of the air conditioner from frosting comprises a main capillary, a control valve, an auxiliary capillary and a one-way valve, wherein one end of the auxiliary capillary is connected with one end of the main capillary through the control valve, the other end of the auxiliary capillary is connected with the other end of the main capillary through the one-way valve, the two ends of the auxiliary capillary are arranged in parallel at the two ends of the main capillary, and the control valve is in electrical connection with a control system of the air conditioner. According to the capillary assembly capable of preventing the outdoor heat exchanger of the air conditioner from frosting, two ends of the capillary assembly are connected with the outdoor heat exchanger and an indoor heat exchanger of the air conditioner with heating and cooling functions, and the capillary assembly can be used to replace an ordinary throttle capillary in the air conditioner with the heating and cooling functions. When the heat exchanger outside a heating operation room of the air conditioner with the heating and cooling functions frosts or is about to frost, the control valve is opened, the one-way valve is opened, the auxiliary capillary and the main capillary work in parallel, system pressure is lowered, and the temperature of the outdoor heat exchanger rises. Therefore, a frosting process of an air conditioner heating operation can be effectively prevented or delayed, service life of the air conditioner is prolonged, comfort of use is improved, and ability and efficiency in the air conditioner heating operation are improved.
Description
Technical field
The utility model relates to air-conditioner and makes the field, particularly a kind of capillary module of preventing the frosting of air-conditioning outdoor heat exchanger, and the improvement that belongs to capillary module is technological.
Background technology
When air conditioner carried out heating operation under the environment of low temperature, the easy frosting of outdoor heat exchanger influenced the heating effect of air-conditioner.Usually air-conditioner relies on the switching of reversal valve to defrost, and promptly heats to transfer refrigerating operaton to.Frequent reversal valve switches certainly will influence the service life of air-conditioner and the comfort level of its use.
The throttle capillary tube that common air conditioner adopts usually is single main capillary, does not have corresponding assisted capillary, and the length of throttle capillary tube is unadjustable, can not play the effect that prevents or postpone the air conditioner heat-production frosting.
Summary of the invention
The purpose of the utility model is to overcome the problems referred to above and the capillary module that can prevent the frosting of air-conditioning outdoor heat exchanger is provided.
In order to achieve the above object, the technical scheme of the utility model: a kind of capillary module of preventing the frosting of air-conditioning outdoor heat exchanger, comprise main capillary and assisted capillary, said assisted capillary is connected in parallel on main two ends capillaceous.
A wherein end of above-mentioned assisted capillary is connected with a main wherein end capillaceous through control valve, and control valve is electrically connected with the control system of air-conditioning.
The other end of above-mentioned assisted capillary is connected with the main other end capillaceous through check valve.
Further, above-mentioned control valve is a magnetic valve.
Effective effect of the utility model is: the two ends of the utility model are connected with indoor heat exchanger with the outdoor heat exchanger of air conditioner respectively, and alternative common throttle capillary tube applies in the air conditioner, when the outdoor heat exchanger frosting of air conditioner heating operation or will frosting the time; Control valve is opened; Check valve is open-minded, assisted capillary and main capillary paralleling work, and system pressure descends; The outdoor heat exchanger temperature rises; And then can effectively prevent or postpone air conditioner heat-production frosting process, improve the service life and the comfort of air-conditioner, ability and efficiency when improving the air-conditioning heating operation.
Description of drawings
Fig. 1 is the capillary module structural representation of the utility model.
Among the figure: 1-master's capillary; The 2-control valve; The 3-assisted capillary; The 4-check valve.
The specific embodiment
Embodiment
The structure of the capillary module of the air-conditioning the prevented outdoor heat exchanger frosting of the utility model is shown in accompanying drawing 1; Comprise main capillary 1, control valve 2, assisted capillary 3 and check valve 4; Assisted capillary 3 two ends are connected in parallel on the two ends of main capillary 1 respectively through control valve 2 and check valve 4, control valve 2 is electrically connected with the control system of air-conditioner.
In the present embodiment, above-mentioned control valve 2 is a magnetic valve.
The two ends of the utility model are connected with indoor heat exchanger with the outdoor heat exchanger of air conditioner respectively, the flow direction of refrigerant in capillary module when direction shown in the arrow is assisted capillary 3 work among Fig. 1.During the air conditioner heating operation, when the outdoor heat exchanger coil temperature was lower than certain value, the control system of air conditioner control magnetic valve was opened; Check valve 4 is open-minded, assisted capillary 3 and main capillary 1 parallel operation, and indoor outside heat exchanger pressure differential reduces; The outdoor heat exchanger load reduces, and the outdoor heat exchanger temperature improves, and then effectively avoids or postponed outdoor heat exchanger frosting process; Reduce the change action of reversal valve, improve life-span and comfort level that air-conditioning uses.And when the outdoor heat exchanger coil temperature was higher than certain value, closed electromagnetic valve did not have the refrigerant assisted capillary 3 of flowing through, and does not influence normal heating effect.During the air-conditioner refrigerating operaton, check valve 4 is closed, and control valve 2 is also closed, and assisted capillary 3 does not have refrigerant to flow through.The utility model does not have influence to the refrigerating operaton of air-conditioner.
