Abstract
An energy-saving yearly refrigeration air conditioner comprises an outdoor unit (18) and an indoor unit (19) which are connected through an air tube (16) and a liquid tube (17). The energy-saving yearly refrigeration air conditioner is characterized in that the indoor unit (19) is mainly composed of an indoor return air valve (1), an indoor heat exchanger (3), an outdoor fresh air valve (4) and a blower (6). The outdoor fresh air valve (4) is mainly controlled by indoor and outdoor temperature differences, and when the outdoor temperature is lower than the indoor temperature and reaches a set value, the outdoor fresh air valve (4) is opened, the indoor return air valve (1) is closed, a compressor (10) stops working, and outdoor low-temperature fresh air is used for reducing the indoor temperature; when the outdoor temperature is not lower than the indoor temperature, the outdoor fresh air valve (4) is closed, the indoor return air valve (1) is opened, and the compressor (10) works to achieve refrigeration. The air conditioner has the advantage of being good in energy-saving effect.
Description
Technical field
the utility model relates to a kind of air-conditioning technical, especially a kind of refrigeration air conditioner, specifically a kind of energy-saving year round cooling air-conditioner.
Background technology
at present, when common year round cooling air-conditioner is spent lower than indoor return air temperature is some at outdoor new air temperature, still by the operation compressor, realize room temperature lowering.When outdoor environment temperature is relatively lower, during outdoor condenser fan high-speed cruising, the outdoor heat exchanger condensing pressure will be very low, the range of operation that can exceed compressor, outdoor condenser fan needs arrangements for speed regulation to be controlled, and a kind of is to adopt outdoor condenser fan start and stop to control condensing pressure, although this control mode cost compare is low, but outdoor condenser fan meeting frequent start-stop, to the operational reliability formation test of unit.Another kind is that outdoor condenser fan adopts many grades of bunchers, and this kind of mode can be relatively good to condensing pressure control effect, but but increased many costs.
Summary of the invention
The purpose of this utility model is for existing compressor, in outdoor temperature, still to work during lower than indoor temperature to cause condensing pressure low and affect the problem of the normal operation of compressor, design a kind of when outdoor new air temperature is spent lower than indoor return air temperature is some, make to stop compressor operating, the new wind of outdoor low temperature is directly sent into to indoor the realization indoor cooling, both reduce condensing pressure control device, realized again the energy-saving year round cooling air-conditioner of energy-saving run.
The technical solution of the utility model is:
A kind of energy-saving year round cooling air-conditioner, it comprises outdoor unit 18 and indoor unit 19, described outdoor unit 18 is connected by tracheae 16 and liquid pipe 17 with outdoor unit 19, described outdoor unit 18 is by low-pressure oil storage 9, compressor 10, outdoor heat exchanger 11, outdoor condenser fan 12, high-pressure reservoir 13, device for drying and filtering 14, electric expansion valve 15 forms, it is characterized in that described indoor unit 19 is mainly by indoor air returning valve 1, indoor heat exchanger 3, outdoor new air-valve 4 and pressure fan 6 form, described outdoor new air-valve 4 is controlled by indoor/outdoor temperature-difference, when outdoor temperature reaches setting value lower than indoor temperature, outdoor new air-valve 4 is opened, indoor air returning valve 1 is closed, compressor 10 quits work, utilize the new wind of outdoor low temperature to realize room temperature lowering, when outdoor temperature is not less than indoor temperature, outdoor new air-valve 4 cuts out, and indoor air returning valve 1 is opened, and compressor 10 work realize refrigeration.
The port of export of described outdoor new air-valve 4 is equipped with outdoor new wind filter 5.
The indoor return air filter 2 of the port of export of described indoor air returning valve 4.
The beneficial effects of the utility model:
The utility model is due to when outdoor new air temperature is spent lower than indoor return air temperature is some, compressor out of service is freezed, the new wind of outdoor low temperature is directly sent into to indoor the realization simultaneously indoor cooling had both been reduced to condensing pressure control device, realized again energy-saving run.
The utility model cost is low, it is simple and convenient to manufacture, and mentality of designing is ingenious, and successful is a kind of function admirable, convenient and practical energy-saving year round cooling air-conditioner.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
As shown in Figure 1.
A kind of energy-saving year round cooling air-conditioner, it comprises outdoor unit 18 and indoor unit 19, outdoor unit 18 is by several low-pressure oil storages 9, compressor 10, outdoor heat exchanger 11, outdoor condenser fan 12, high-pressure reservoir 13, device for drying and filtering 14, electric expansion valve 15 forms, indoor unit 19 is by indoor air returning valve 1, indoor return air filter 2, indoor heat exchanger 3, outdoor new air-valve 4, outdoor new wind filter 5, pressure fan 6 forms outdoor unit 18 and is connected by copper tracheae 16 and copper liquid pipe 17 with outdoor unit 19, on the tracheae 16 that connects indoor unit 19 and outdoor unit 18 and liquid pipe 17, tracheae stop valve 7 and liquid pipe stop valve 8 are installed.When outdoor new air temperature is not less than that indoor return air temperature is some spends, by air returning valve 1,10 operations of unlatching compressor in new air-valve 4, opening chamber outside close chamber, indoor return air first filters the laggard indoor heat exchanger 3 that enters by return air filter 2, low temperature return air after being processed by indoor heat exchanger 3 by pressure fan 6 again flows to room temperature lowering, realizes refrigerating function.When outdoor new air temperature is spent lower than indoor return air temperature is some, by stopping air returning valve 1 in compressor 10 operation, the outer new air-valve 4 of opening chamber, close chamber, outdoor low temperature is newly by directly flowing to room temperature lowering by pressure fan 6 by the new wind of outdoor low temperature again after outdoor new wind filter 5 filtrations.Because now compressor 10 need not be worked, can realize energy-conservation refrigerating operaton.
The utility model do not relate to part as the annexation of the each several part of indoor unit and outdoor unit all the prior art that maybe can adopt same as the prior art realized.
