Detachable air conditioner in the market is divided into three kinds by adaptable climate type: T1, T2, T3.The ambient air temperature that this air-conditioner of three types adapts to has nothing in common with each other, and the T1 type adapts to temperate climate, and the T3 type adapts to megathermal climate.The air-conditioner of T1 type should not use in T3 high temperature area; because when T1 type detachable air conditioner moves under very abominable megathermal climate; the outside condensing pressure is very high; delivery temperature improves rapidly; compressor carries out overload operation; will cause high frequent protection like this, can not continuous cooling, and then have influence on the service property (quality) and the service life of air-conditioner.In existing air-conditioner product, from technical scheme, corresponding to different weathers, the selected parts of dissimilar air-conditioners are different.Such as, the air-conditioner in T3 high temperature area just must adopt the high temperature resistant dedicated compressor of T3, increases condenser etc., and this has just increased Products Development cost and Material Cost greatly.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of prior art, provides a kind of simple in structure, need not adopt high temperature resistant specialized spare part, saves cost, still can adapt to automatically in the T3 area, a kind of T1 type high temperature self-adaption separated air conditioners of operate as normal.
The technical scheme that realizes the utility model purpose is: the utility model includes refrigerating circuit, refrigerating circuit includes compressor, condenser, main capillary, evaporimeter, also be parallel with auxiliary throttling branch road in refrigerating circuit, auxiliary throttling is propped up route filter, unloader and assisted capillary and is connected to form.
In technique scheme, the concrete parallel way of auxiliary throttling branch road and refrigerating circuit is:
Filter inlet and condensator outlet join, and assisted capillary joins by threeway and evaporator feed pipe;
Or filter inlet and compressor air-discharging pipeline join, and assisted capillary joins by threeway and evaporator feed pipe;
Or join in the middle part of filter inlet and the condenser, assisted capillary joins by threeway and evaporator feed pipe;
Or filter inlet and condensator outlet join, and assisted capillary joins by threeway and compressor air suction pipeline;
Or filter inlet and compressor air-discharging pipeline join, and assisted capillary joins by threeway and compressor air suction pipeline;
Also can be that filter inlet and condenser middle part joins, assisted capillary joins by threeway and compressor air suction pipeline.
The beneficial effects of the utility model are: owing to adopt the technical scheme of throttling branch road in parallel in refrigerating circuit; when the outside condensing pressure exceeds upper safety limit (being the opening pressure of unloader); unloader is opened; the throttling branch road is open-minded; can effectively improve the discharge coefficient of whole capillary member; refrigerant flow increases; condensing pressure is reduced; reduce delivery temperature; effectively prevent compressor protection, thereby make the air-conditioner can continuous cooling, and can be by the coupling assisted capillary; make whole discharge coefficient capillaceous be adjusted to the best, and then the complete machine performance is optimized.The utility model is simple in structure, need not adopt high temperature resistant specialized spare part, saves cost, long service life, and the high temperature high voltage resistant performance is good, can adapt to automatically in the T3 area and operate as normal.
