Embodiment 1

[0020] Such as figure 1 As shown, the whole equipment includes the following components: compression device 1, four-way valve 2, first throttling mechanism 4, second throttling mechanism 5, user side heat exchanger 3, heat source side heat exchanger 6, heater 8 , the first flow control valve 41 and the second flow control valve 42; the first throttling mechanism 4, the second throttling mechanism 5, the first flow control valve 41 and the second flow control valve 42 are electronic expansion valves.

[0021] Compression device 1 has three connection nodes of high-pressure connection point B, low-pressure connection point C, and normally open connection point A, and is made up of low-pressure compressor 1-1, high-pressure compressor 1-2 and the third one-way valve 23; Their connection The method is as follows: the inlet port of the low-pressure compressor 1-1 is connected to the low-pressure connection point C of the compression device 1, the outlet port of the low-pressure com...

Embodiment 2

[0055] Such as figure 2 As shown, the difference from Embodiment 1 is that a third throttling mechanism 7 is added in the system. Fifty-two pipelines 52 are connected. Such as figure 2 As shown, at this time, the first flow control valve 41 and the second flow control valve 42 can be replaced by the first one-way valve 21 and the second one-way valve 22 respectively; their connection mode is: the first one-way valve 21 The inlet end is connected with the sixty-first pipeline 61, the outlet end of the first one-way valve 21 is connected with the heater 8 through the fifty-first pipeline 51, and the outlet end of the second one-way valve 22 is connected with the outlet end of the first one-way valve 21 and The fifty-first pipeline 51 between the heaters 8 is connected, and the inlet port of the second one-way valve 22 is connected with the sixty-second pipeline 62 .

[0056] This example figure 2 The scheme shown can also realize embodiment 1 figure 1 The function of the...

Embodiment 3

[0067] Such as image 3 As shown, with Example 2 figure 2The difference of the solutions shown is that the compression device 1 is composed of a low-pressure compressor 1-1, a high-pressure compressor 1-2, a third one-way valve 23, a second four-way valve 80 and a capillary tube 9. Their connections are as follows: the inlet port of the low-pressure compressor 1-1 is connected to the low-pressure connection point C of the compression device 1, the outlet port of the low-pressure compressor 1-1 passes through the inlet port of the high-pressure compressor 1-2, and the high-pressure compressor 1-2 2. The outlet port is connected to the high-pressure connection point B of the compression device 1. The inlet port of the third one-way valve 23 is connected to the pipeline between the outlet port of the low-pressure compressor 1-1 and the inlet port of the high-pressure compressor 1-2. The third one-way valve The outlet port of the valve 23 is connected to the pipeline between the...

Abstract

The invention discloses air conditioning and refrigerating equipment which comprises a compressor, a first four-way valve, a first throttle mechanism, a second throttle mechanism, a user-side heat exchanger, a heat source-side heat exchanger, a heater, a first flow direction control valve and a second flow direction control valve. The compressor is provided with three connection points, namely, a high-pressure connection point, a low-pressure connection point and a normally-open connection point, wherein, the high-pressure connection point of the compressor is connected with a high-pressure node of the first four-way valve through a 60th pipe; the low-pressure connection point of the compressor is connected with a low-pressure node of the first four-way valve through a 63rd pipe; and the normally-open connection point of the compressor is connected with any one of the two reversing nodes of the first four-way valve through a 67th pipe, the heat source-side heat exchanger, the second throttle mechanism, a 58th pipe, a 57th pipe, the first throttle mechanism, the user-side heat exchanger and a 64th pipe sequentially. The air conditioning and refrigerating equipment has the advantages of simple structure, reliable operation and low cost and can realize various functions of refrigerating, heating, producing domestic hot water and the like.

Description

technical field [0001] The invention relates to an air-conditioning and refrigeration device with multiple functions, belonging to the technical field of refrigeration. Background technique [0002] For a long time, the winter and summer dual-purpose air-conditioning and refrigeration equipment composed of a compression mechanism, a four-way reversing mechanism, a heat source side heat exchanger, a user side heat exchanger and a throttling mechanism, when used for cooling, use the user side heat exchanger Cool the indoor air or produce chilled water, and the condensation heat generated by refrigeration is discharged into the environment through the heat exchanger on the heat source side (such as: outdoor air, surface water, ground water or soil, etc.); when used for heating, use the heat source side heat exchanger The heater absorbs heat from the environment, and then produces hot water or heats indoor air through the user-side heat exchanger. As we all know, the above-ment...
