[0056] refer to figure 2, in this embodiment, the refrigeration system 100 includes the compressor 1 , the four-way valve 2 , the outdoor heat exchanger 3 , the throttling device 4 and the indoor heat exchanger 5 . The refrigeration system 100 also includes a three-way valve 6, the three-way valve 6 has a fifth valve port 61, a sixth valve port 62 and a seventh valve port 63, the fifth valve port 61 is connected to the second exhaust port 142, the sixth valve port The port 62 is connected to the second outdoor heat exchange port 32 , and the seventh valve port 63 is connected to the inner cavity of the casing 11 . Thus, when the fifth valve port 61 communicates with the sixth valve port 62, the second exhaust port 142 communicates with the second outdoor heat exchange port 32 and is blocked from the main exhaust port 111; When the seven valve ports 63 are connected, the second exhaust port 142 is connected to the main exhaust port 111 and blocked from the second outdoor heat...

Embodiment 3

[0059] refer to image 3 , in this embodiment, the refrigeration system 100 includes the compressor 1 , the four-way valve 2 , the outdoor heat exchanger 3 , the throttling device 4 and the indoor heat exchanger 5 . The refrigeration system 100 also includes a three-way valve 6, the three-way valve 6 has a fifth valve port 61, a sixth valve port 62 and a seventh valve port 63, the fifth valve port 61 is connected to the second exhaust port 142, the sixth valve port The port 62 is connected to the second outdoor heat exchange port 32 , and the seventh valve port 63 is connected to the inner cavity of the housing 11 . Thus, when the fifth valve port 61 communicates with the sixth valve port 62, the second exhaust port 142 communicates with the second outdoor heat exchange port 32 and is blocked from the main exhaust port 111; When the seven valve ports 63 are connected, the second exhaust port 142 is connected to the main exhaust port 111 and blocked from the second outdoor hea...

Abstract

The invention discloses a refrigerating system and a control method thereof. The refrigerating system comprises a compressor, an outdoor heat exchanger, a throttling device and an indoor heat exchanger which are sequentially connected from head to tail to form a loop. The compressor comprises a shell body and a compressing mechanism, a main air exhaust port is formed in the shell body, the compressing mechanism is provided with a first compressing cavity and a second compressing cavity which are independent with each other, and the first air exhaust port of the first compressing cavity suits to communicate with the main air exhaust port. The refrigerating system further comprises a four-way valve which is provided with valve ports from the first one to the fourth one; the main air exhaust port is connected with the first valve port; a first air intake port of the first compressing cavity and a second air intake port of the second compressing cavity are both connected with the fourth valve port; and the second air intake port of the second compressing cavity communicates with one of the main air exhaust port and the outer door heat transfer or is disconnected with the other one of the main air exhaust port and the outer door heat transfer selectively. According to the refrigerating system, defrosting can be conducted at the same time with heating, defrosting effect is good, defrosting time is short, and heating quantity on average is high.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a refrigeration system and a control method thereof. Background technique [0002] In the related art, some refrigeration equipment has non-stop defrosting function, but the actual application effect is not very good. The main reason is: in order to prevent too much refrigerant from participating in the defrosting, the defrosting flow path is controlled by a thin tube or a throttling device to balance the pressure, so that the temperature of the defrosting flow path is not high and the defrosting time is long. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. Therefore, the present invention proposes a refrigeration system, which can realize defrosting while heating, has good defrosting effect and short defrosting time. [0004] The present invention also proposes a contr...
