the present embodiment is made up of off-premises station and indoor set, and off-premises station comprises outdoor compressor 1 and outdoor condenser, and indoor evaporator 18 is equipped with in indoor set inside, and indoor set is also provided with exhaust outlet 16, fan and air-vent 17.
indoor set is connected by pipeline with off-premises station, off-premises station is equipped with condenser 7, refrigeration choke valve 6 and cold-storage choke valve 5.The pipeline that outdoor compressor 1 is connected with one of them port of cross valve 9 is equipped with the second magnetic valve 10.
other three ports of cross valve 9 are connected with a port of evaporimeter 3 in the arrival end of condenser 7, the suction end of outdoor compressor 1 and cabinet respectively, the port of export of condenser 7 is connected with a port of triple valve 8, two other port of triple valve 8 communicates with refrigeration choke valve 6 and cold-storage choke valve 5 respectively, cold-storage choke valve 5 is connected with a port of cold-storage groove 4, and the another port of cold-storage groove 4 is connected with the port of export with the arrival end (suction end) of outdoor compressor 1 respectively by two different pipelines.
cold-storage groove 4 is contained in indoor set body; The first pipeline 19 that cold-storage groove 4 is connected with outdoor compressor 1 suction side is equipped with boost pump 2, the 6th magnetic valve 14, the 4th magnetic valve 12 and cross valve 9 successively; First pipeline 19 is connected with evaporimeter in cabinet 3 by the 3rd pipeline 21, the 3rd pipeline is equipped with the 5th magnetic valve 13.
the second pipeline 20 that cold-storage groove 4 is connected with outdoor compressor 1 port of export is equipped with boost pump 2, the 6th magnetic valve 14 and the 3rd magnetic valve 11 successively.
the port of export pipeline of cold-storage groove 4 is equipped with boost pump 2, boost pump 2 adopts vapour-liquid pump, the port of export of boost pump 2 is connected with the arrival end of outdoor compressor 1 by the first pipeline, boost pump 2 as ice-melt, release cold time refrigerant circulation servicing unit, improve systemic circulation stability, release cold working cycles and undertaken by evaporimeter 3 in the 6th magnetic valve 14, the 5th magnetic valve 13, cabinet and the 7th magnetic valve 15.
a port of the 5th magnetic valve 13 is connected with evaporimeter in cabinet 3, and another port in cabinet on evaporimeter 3 is connected with refrigeration choke valve 6; Cold-storage groove 4 is contained in indoor set body.Cold-storage groove 4 volume is little, is held into indoor set, need not take up space in addition in indoor.
evaporimeter 3 is placed in the middle and lower part of indoor set, and the middle and upper part of indoor set is used for installing cold-storage groove 4, and exhaust outlet 16 is positioned at the top of cabinet-type air conditioner.Air exhausting structure increases by an air duct and invests interior of equipment cabinet, to be drawn from air-vent 17 by wind.As shown in Figure 2.
cold-storage groove 4 is built with ethylene glycol and ice hockey; Cold-storage groove 4 is equipped with little evaporimeter.
connecting line between cold-storage choke valve 5 and refrigeration choke valve 6 is equipped with the 7th magnetic valve 15.
in refrigeration and heat pump two kinds of conventional operating mode bases, add cold-storage in the present embodiment and release cold pattern, each pattern works alone; Two choke valves are provided with: cold-storage choke valve 5, refrigeration choke valve 6 in system; Refrigeration choke valve with 6 for conventional refrigerant, cold-storage choke valve 5 for cold-storage,
this is because conventional refrigerant is from evaporating temperature needed for cold-storage different and determine.The minimum evaporating temperature of conventional air-conditioning cold-producing medium is generally about 2 DEG C, and this is too high concerning temperature cold-storage, because store identical cold, ice can be little a lot of times than the volume of water, so native system separately establishes a cold-storage choke valve 5, its evaporating temperature is made to drop to-10 to-8 DEG C, to reduce cold-storage groove volume.
systemic circulation is as accompanying drawing 1:
the first: refrigeration mode working cycles; Circuit is followed successively by: evaporimeter 3 in outdoor compressor 1, second magnetic valve 10, cross valve 9, condenser 7, triple valve 8, refrigeration choke valve 6, cabinet.Because temperature when cold-producing medium gasifies in pipeline is lower than the temperature of indoor evaporator, that is it will absorb heat in air indoor.Cold-producing medium after heat absorption becomes again the gas of normal temperature and pressure, and is sucked back by outdoor compressor 1 through the 5th magnetic valve 13 and cross valve 9.
the second: heat pump mode working cycles
the circulation route of cryogen is just in time contrary compared with refrigeration mode.The heat absorption of evaporimeter 3 under refrigeration mode in heating becomes heat radiation, plays condensation.The heat radiation of condenser 7 under refrigeration mode becomes heat absorption, plays evaporation.Refrigerant circulation route is followed successively by: the suction end of outdoor compressor 1, the 3rd magnetic valve 11, indoor evaporator (condensation) 3, refrigeration choke valve 6, triple valve 8, condenser (evaporation) 7, cross valve 9, outdoor compressor 1.
the third: cold-storage work pattern circulates
circulation route is successively: the little evaporimeter in compressor 1, second magnetic valve 10, cross valve 9, condenser 7, triple valve 8, cold-storage choke valve 5, cold-storage groove 4; Cold-producing medium from this evaporimeter out after to get back to the suction end of outdoor compressor 1 through boost pump 2, the 6th magnetic valve 14, the 4th magnetic valve 12, cross valve 9.
4th kind: release the circulation of cold work pattern:
off-premises station all quits work, and the 6th magnetic valve 14 and the 7th magnetic valve 15 are opened, all the other Close Alls.Form loop between evaporimeter 3 in little evaporimeter and cabinet in cold-storage groove 4, cold-producing medium relies on self-characteristic in pipeline, start constantly to carry out gas, liquid change and carry out heat absorption and release.The circulation of cold-producing medium in pipeline has been assisted by gas, liquid gravity difference or the miniature boost pump 2 of inserting in pipeline.
the utility model is not limited to the arrangement form etc. of each magnetic valve cited by above-described embodiment and pipeline, as long as the cold-storage groove added with little evaporimeter participate in the structure of cold-storage duty cycle mode, is all considered as within protection domain of the present utility model.
