Abstract
The present invention relates to a high temperature self-adaption separated air conditioner which comprises a cooling loop, wherein the cooling loop comprises a compressor, a condenser, a main capillary and an evaporator; an auxiliary throttling branch circuit is arranged in the cooling loop in parallel and is formed by connecting a filter, an unloading valve and an auxiliary capillary. Because the present invention adopts the technical scheme that the throttling branch circuit is connected in the cooling loop in parallel, the unloading valve is opened and the throttling branch circuit is switched on when the condensing pressure outside the air conditioner goes beyond a safe upper limit so as to effectively enhance the flow coefficient of a whole capillary component and increase the flow quantity of refrigerant, so the condensing pressure and the exhaust temperature are lowered and the protection of the compressor is effectively prevented to make the air conditioner continuously refrigerate. The present invention has the advantages of simple structure, no need of adopting high-temperature resisting special components, cost saving, long service life and favorable performance of high-temperature and high-pressure resistance, and can still work normally in T3 regions.
Description
Technical field
The utility model relates to the air-conditioner technical field, specifically is a kind of high temperature self-adaption separated air conditioners, belongs to the improvement technology of existing detachable air conditioner.
Background technology
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, in refrigerating circuit, also be parallel with auxiliary throttling branch road, auxiliary throttling is propped up route filter, unloader and assisted capillary and is connected to form, the concrete parallel way of above-mentioned auxiliary throttling branch road and refrigerating circuit is: filter inlet and compressor air-discharging pipeline join, and assisted capillary joins by threeway and evaporator feed pipe or the compressor air suction pipeline joins.
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.
Description of drawings
Accompanying drawing 1 is the refrigerating circuit structural representation of the utility model embodiment one;
Accompanying drawing 2 is the refrigerating circuit structural representation of the utility model embodiment two.
The specific embodiment
Below in conjunction with drawings and Examples the specific embodiment of the present utility model is described further.
Embodiment one:
As shown in Figure 1, the refrigerating circuit of the utility model embodiment one includes: compressor 1, condenser 2, unloader 3, filter 4, assisted capillary 5, main capillary 6, threeway 7, evaporimeter 8, wherein, filter 4 inlets join with compressor 1 blast pipe, two outlets of filter are joined with unloader 3 and condenser 2 inlets respectively, and assisted capillary 5 joins by threeway 7 and evaporimeter 8 import feed pipes.
Embodiment two:
As shown in Figure 2, the refrigerating circuit of the utility model embodiment two includes: compressor 1, condenser 2, unloader 3, filter 4, assisted capillary 5, main capillary 6, threeway 7, evaporimeter 8, wherein, filter 4 inlets join with compressor 1 blast pipe, 4 two outlets of filter are joined with unloader 3 and condenser 2 inlets respectively, and assisted capillary 5 joins by threeway 7 and compressor 1 suction line.
In the utility model course of work, when outdoor environment temperature when not being very abominable, when outside pressure was lower than unloader 3 opening pressures, unloader 3 was in closed condition, the cold-producing medium main capillary 6 of only flowing through; When outside pressure exceeds upper safety limit (being the opening pressure of unloader 3); unloader 3 is opened; cold-producing medium flow through simultaneously main capillary 6 and assisted capillary 5; can effectively improve the discharge coefficient of capillary member; refrigerant flow increases, and condensing pressure is reduced, and reduces delivery temperature; effectively prevent compressor 1 protection, thereby make the air-conditioner can continuous cooling.The experiment proved that the utility model still can operate as normal in the maximum running refrigerating operating mode of national standard T3 (indoor doing/wet-bulb temperature: 32 ℃/23 ℃, outdoor doing/wet-bulb temperature: 52 ℃/31 ℃).
