The specific embodiment
Basic design of the present invention is, cold-producing medium is set regulates bypass, and the unnecessary cold-producing medium when making system's refrigeration is canned with liquid storage.
For further understanding basic principle of the present invention and structure, present invention is described below in conjunction with drawings and Examples.
Referring to Fig. 1, be one of the energy-saving type air conditioner of the utility model band cold-producing medium regulatory function preferred embodiment, form by parts such as compressor 1, cross valve 2, condenser 3, oil return capillary 4, control valve 5, fluid reservoir 6, orifice union 7, first stop valve 8, evaporimeter 9, second stop valves 10, wherein: set gradually compressor 1, four-way change-over valve 2, condenser 3 and evaporimeter 9 on the refrigerant circulation loop, this condenser 3 is communicated with compressor 1 with evaporimeter 9 by four-way change-over valve 2 selectivity, makes cold-producing medium heat/commutation when freezing; The cold-producing medium that is provided with fluid reservoir 6 is regulated bypass, and its first node P1 is between condenser 3 and evaporimeter 9, and Section Point P2 is between the air entry and four-way change-over valve 2 of compressor 1; Like this, air-conditioning can be according to the flow of the different adjustment cold-producing medium of refrigerating/heating pattern, realizes heating the purpose that improves refrigeration EER on the basis of COP.
In the present embodiment, between fluid reservoir 6 and the first node P1 control valve 5 is set, it typically is magnetic valve.In addition, controller (scheming not shown) is set, it is electrically connected this control valve 5, output control valve start signal when refrigeration, output control valve shutdown signal when heating.Thus, realize the automatic control of cold-producing medium adjusting bypass.
In addition, be provided with oil return capillary 4 between fluid reservoir 6 and the Section Point P2, make in the process of refrigerastion compressor oil get back among the compressor 1, to guarantee the lubricated of compressor by oil return capillary 4.
As shown in Figure 1, the front end of evaporimeter 9 is provided with first stop valve 8, and the rear end is provided with second stop valve 10; Between first stop valve 8 and the described first node P1 orifice union 7 is set, it is electric expansion valve or capillary, has restriction effect preferably.
The circulation route of cold-producing medium below is described, solid line is represented the flow direction of cold-producing medium under the refrigeration mode among Fig. 1, and dotted line is represented the flow direction of cold-producing medium under the heating mode.
In the air-conditioning heating process, the glide path of cold-producing medium is compressor 1 → four-way change-over valve 2 → evaporimeter 9 → orifice union 7 → condenser 3 → four-way change-over valve 2 → compressor 1, finishes heating circulation.This moment, control valve 5 was closed not conducting, did not have cold-producing medium in the fluid reservoir 6, and ownership cryogen participates in heating circulation in the air-conditioning system.
In the air conditioner refrigerating running, the air-conditioning system cold-producing medium divides two-way to flow: first refrigerant circulation loop, and its flow of refrigerant route is: compressor 1 four-way change-over valve 2 → condenser 3 → orifice union 7 → evaporimeter 9 → four-way change-over valve 2 → compressor 1; It two is that cold-producing medium is regulated bypass, and its flow of refrigerant route is: compressor 1 → four-way change-over valve 2 → control valve 5 → fluid reservoir 6 → oil return capillary → four-way change-over valve 2 → compressor 1.Thus, finish kind of refrigeration cycle by this two-route wire.At this moment, control valve 5 is opened conducting, will store unnecessary cold-producing medium in the fluid reservoir 6, and the compressor oil in the fluid reservoir 6 is got back in the compressor 1 by oil return capillary 4, guarantees the lubricated of compressor 1 thus.
In the foregoing description, the present invention compares with common heat pump air conditioner, has increased magnetic valve 5, fluid reservoir 6 and oil return capillary 4.When refrigerating operaton, use fluid reservoir 6 that cold-producing medium unnecessary in the system is stored, help improving the refrigerating operaton Energy Efficiency Ratio.
Only be preferred implementation of the present invention below, should be pointed out that above-mentioned preferred implementation should not be considered as limitation of the present invention, protection scope of the present invention should be as the criterion with claim institute restricted portion.For those skilled in the art, without departing from the spirit and scope of the present invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
