Abstract
The utility model discloses a cabinet air conditioner, relating to the technical field of air conditioners. The utility model has the technical proposal that a four-way valve is connected with air inlets which are connected with a plurality of compressors in parallel respectively, and the air outlets which are connected with a plurality of compressors in parallel are connected with the four-way valve respectively. The utility model is a cabinet air conditioner with a single-phase power supply, has the advantages of large starting current reduction, large specification refrigerating capacity, and energy saving.
Description
The utility model cabinet air conditioner relates to air-conditioning technical field, is applicable to adopt single phase poaer supply to make the big cabinet air conditioner of refrigerating capacity.
The refrigeration system (Fig. 1) of existing cabinet air conditioner is the system of single compressor normally, is made up of evaporimeter, cross valve, compressor, condenser, capillary or expansion valve.The weak point of this cabinet air conditioner is that current peak is concentrated when starting, and often exists to start difficulty under the relatively poor situation of electrical network condition.The cabinet air conditioner of single phase poaer supply particularly, its starting current with constant power the time is bigger, puts the problem of the specification below 8000W usually so the cabinet air conditioner of single phase poaer supply often exists refrigeration.Also exist the problem that to use the cabinet air conditioner of refrigerating capacity specification big (more than the 10000W) in the place of no three phase mains simultaneously.
The purpose of this utility model provides a kind of cabinet air conditioner, and this air-conditioner is in same refrigeration system, and a plurality of compressors in parallel carry out substep and start the purpose that reduces starting current to reach.
The design of the utility model cabinet air conditioner (Fig. 2) is that cabinet air conditioner is by evaporimeter (1), cross valve (2), a plurality of compressors (3 in parallel, 4), capillary or expansion valve (5) condenser (6) is formed, its structure connect be cabinet air conditioner be with copper pipe with the gas outlet of evaporimeter (1) be connected cross valve (2) 7 on, connected a plurality of compressor (3 in parallel with copper pipe in addition in 8 minutes of cross valve (2), 4) air inlet, compressor (3 in parallel, 4) gas outlet respectively with copper pipe connect cross valve (2) 10) on, (9) of cross valve connect condenser (6) with copper pipe, condenser (6) constitutes with the air inlet that copper pipe connects evaporimeter (1) with the air inlet of copper pipe connection capillary or expansion valve (5), the gas outlet of capillary or expansion valve (5).
The effect of the utility model cabinet air conditioner is compared with prior art: because the off-premises station of this cabinet air conditioner a plurality of compressors in parallel are when starting, start first earlier, after first starting current peak value reduces, restart second, restart the 3rd by this way, starting current is compared with the cabinet air conditioner of existing separate unit compressor and can be reduced more than 50% after tested, has to reduce the big effect of starting current, and can produce the single phase poaer supply cabinet air conditioner of big specification refrigerating capacity; Simultaneously aspect Load Regulation, can when design temperature and environment temperature differ greatly, can running at full capacity be whole compressor operatings.Right in environment temperature near design temperature, can the sub-load running promptly reduce compressor operating platform number, can reach purpose of energy saving like this.
Fig. 1 is a prior art cabinet air conditioner refrigerating system figure;
Fig. 2 is the utility model cabinet air conditioner refrigerating system figure.
The embodiment of the utility model cabinet air conditioner is that the cabinet air conditioner (five cabinet-type air conditioners) that refrigerating capacity of production is 12000W is: selecting the accurate refrigerating capacity of two station symbols for use with the cabinet air conditioner of single phase poaer supply five horsepowers of prior art manufacturing is the single phase poaer supply compressor (3 of 6000W, 4), with copper pipe the gas outlet of the evaporimeter (1) of prior art single phase poaer supply five horsepower refrigeration systems is welded on prior art cross valve (2) 7 on, 8 usefulness copper pipes of cross valve are welded on two compressors (3 in parallel, 4) on the air inlet, two compressors (3 in parallel, 4) gas outlet with copper pipe be welded on cross valve 10 on, 9 usefulness copper pipes of cross valve are welded on the air inlet of prior art condenser (6), the gas outlet of condenser (6) is welded on copper pipe in the air inlet of capillary or expansion valve (5), and its gas outlet is welded on copper pipe on the air inlet of evaporimeter (1) and constitutes.When installing and using, start first compressor earlier, restart second compressor after 5 seconds, starting current is 70A after tested, and is also littler than the starting current (about 80A) of three cabinet-type air conditioners of single phase poaer supply in the prior art.When needing Load Regulation, also can 0%, 50%, 100% third gear adjustable, energy-conservation effect is arranged.
Claims (1)
1, a kind of cabinet air conditioner, refrigeration system by cabinet air conditioner has evaporimeter, cross valve, the compressor condenser, capillary or expansion valve are formed, it is characterized in that cross valve (2) connects the air inlet of a plurality of compressors in parallel respectively, the cabinet air conditioner that the gas outlet of a plurality of compressors in parallel connects cross valve (2) respectively constitutes.
