Technical problem to be solved in the utility model provides a kind of heat pump assembly, and it simple in structure, easy to use can make off-premises station postpone frosting quickly and efficiently when heating, thereby also can realize heating continuously in the weather of cold.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of heat pump assembly, it comprises compressor, indoor heat exchanger, outdoor heat exchanger, triple valve and throttle part, compressor is connected with outdoor heat exchanger with indoor heat exchanger respectively, indoor heat exchanger is connected with outdoor heat exchanger by throttle part and triple valve, and throttle part comprises main capillary and the auxiliary throttling branch road of the adjustable throttle amount size that is connected in parallel with it.When heat pump assembly is worked, when the indoor condensing pressure exceeds certain limit or outdoor heat exchanger coil temperature when being lower than certain numerical value, or other can judge that outdoor heat exchanger is whether during the situation of frosting, automatically auxiliary throttling branch road is regulated, to improve the discharge coefficient of whole capillary member, refrigerant flow is increased, condensing pressure reduces, the outside evaporating pressure raises, thereby just can effectively postpone the outdoor heat exchanger frosting.
As a kind of preferred version of the present utility model, the route unloader is propped up in the auxiliary throttling of described adjustable throttle amount size and assisted capillary is formed, indoor heat exchanger is connected with main arrival end capillaceous with unloader respectively, the main port of export capillaceous is connected with outdoor heat exchanger, and the port of export of unloader is connected with assisted capillary again.Indoor condensing pressure value when the opening pressure of unloader is set to the outdoor heat exchanger frosting, when outdoor heat exchanger was wanted frosting, unloader was opened like this, and the throttling branch road is open-minded, thereby increases the flow of cold-producing medium, effectively delay chamber external heat exchanger frosting.
As another kind of preferred version of the present utility model, auxiliary throttling branch road includes only electric expansion valve, the output of temperature-sensing element and electric expansion valve are connected with its electric control gear respectively, electric control gear is provided with automatically controlled chip, be solidified with heating chamber external delays frosting program in this chip, the pin of this outdoor delay frosting program is connected with temperature-sensing element, and indoor heat exchanger is connected with main arrival end capillaceous with electric expansion valve respectively, and the main port of export capillaceous is connected with outdoor heat exchanger.Electric control gear, during electric control gear work, be installed in the automatically controlled chip that temperature-sensing element on the outdoor heat exchanger coil pipe can pass to temperature information electric control gear, the heating chamber external delays frosting program of solidifying in the automatically controlled chip will whether frosting be judged to outdoor heat exchanger automatically, if frosting, to control the open degree of electric expansion valve by electric control gear, thereby increase the flow of cold-producing medium, effectively postpone the outdoor heat exchanger frosting.
In addition, in aforesaid heat pump assembly, also can between indoor heat exchanger and throttle part, be connected a filter, remove the impurity in the cold-producing medium, thereby improve the effect of heat exchange.
With respect to prior art, the beneficial effects of the utility model are:
The utility model is owing to adopt the technical scheme of the throttling branch road of adjustable throttle amount in parallel on main capillary, when the indoor condensing pressure exceeds certain limit or outdoor heat exchanger coil temperature when being lower than certain numerical value, or other can judge that outdoor heat exchanger is whether during the situation of frosting, auto-action that can be by unloader or electric-control system are to electronic expansion valve controls, intelligently the running status of heat pump is monitored and judged, regulate the refrigerant flow coefficient of heat pump, heat frosting thereby postponed off-premises station effectively.The utility model is simple in structure, need not adopt low temperature resistant specialized spare part, saves cost, long service life, and resistance to low temperature is good, can be widely used on the present domestic air conditioning, also can adapt to automatically in China northern territory and operate as normal.
