Example

[0030] First embodiment

[0031] figure 1 It shows a single-cylinder type first rotary compressor 1a equipped with a capacity control type capable of variable cooling capacity through capacity control, and a normal general fixed capacity type second rotary compressor that controls cooling capacity through continuation and stop of operation 1b refrigeration cycle.

[0032] In the cooling mode, when both the first rotary compressor 1a and the second rotary compressor 1b are in operation, the refrigerant gas discharged from the first discharge pipe 3a and the second discharge pipe 3b of the two compressors passes through The first check valve 8A and the second check valve 8b flow into the four-way switching valve 4, reach the outdoor heat exchanger 6, and become condensed refrigerant. Then, it evaporates in the indoor heat exchanger 5 through the expansion valve 7 and reaches the first liquid storage tank 13a and the second liquid storage tank 13b with respective compressors. Therea...

[0058] Second embodiment

[0059] In the second embodiment of the present invention, a capacity-controlled first rotary compressor and two fixed-capacity second and third rotary compressors without capacity control means are simultaneously mounted in an air conditioner or On the refrigeration system. As a result, Figure 7 As shown, compared with the first embodiment, the maximum cooling capacity can be made larger. Moreover, as in the first embodiment, the variability of the cooling capacity can be changed linearly and freely.

[0060] When the first rotary compressor, the second rotary compressor, and the third rotary compressor operate at the same time, this is referred to as A+B+C mode operation. As described above, by arbitrarily increasing the number of fixed-capacity rotary compressors, the increase can be controlled in a controlled manner while maintaining the cooling capacity variable means of the first embodiment.

[0061] Next, the main points of the invention will be ...

Abstract

The invention relates to a refrigeration circulating system and an application thereof. The refrigeration circulating system comprises a condenser, an evaporator and an expansion valve. The refrigeration circulating system is characterized by also comprising a compressor unit, wherein the compressor unit comprises a capacity-controllable single-cylinder first rotary compressor and a capacity-fixed second rotary compressor, and the first rotary compressor and the second rotary compressor are simultaneously connected into the refrigeration circulating system; the first rotary compressor comprises a seal housing, and an electric motor part and a compressing mechanism part are arranged in the seal housing; the compressing mechanism part comprises a cylinder, a round piston, a slide spring, a crank shaft, a main bearing and a supplementary bearing, wherein the round piston is capable of making eccentric rotation in a compressing cavity of the cylinder, the slide spring abuts against the back part of a slip sheet, the front end of the slip sheet can be connected with the circumference of the piston, the crank shaft is used for driving the piston to rotate, and the main bearing and the supplementary bearing are used for supporting the crank shaft; and the first rotary compressor is provided with a pressure switching device. The invention has the characteristics of low manufacturing cost and wide application range, and improves the energy efficiency and the comfort of the air conditioner.

Description

technical field [0001] The invention relates to a refrigeration cycle system and its application. Background technique [0002] In recent years, the method of changing the number of revolutions of the motor through frequency conversion technology to improve air conditioning capacity control and energy efficiency has become popular. However, these methods are technically difficult to apply, coupled with reliability problems caused by the number of electronic components, and have the disadvantages of increased manufacturing costs. Therefore, for this subject, research on cooling capacity control by a capacity control type rotary compressor having advantages in ease of application, reliability, and cost is underway. Such as [0003] [Patent Document 1] Patent Publication Heisei 1-247786 [0004] [Patent Document 2] Patent Publication Heisei 15-31114 [0005] [Patent Document 3] Patent Publication 2005-207306 [0006] [Patent Document 4] Patent Publication 2008-128231 [0...
