Problems solved by technology

[0003] 1) After the superheated vapor of the refrigerant discharged from the compression mechanism 1 enters the third heat exchanger 8, it usually only releases part of the heat. Therefore, the refrigerant coming out of the third heat exchanger 8 may be all gas, or gas-liquid Two-phase mixture, so when these refrigerants pass through the second throttling mechanism 7, a large pressure drop (ie: cycle resistance) will occur, so it will adversely affect the cycle performance of air-conditioning and refrigeration equipment

Embodiment 1

[0033] Such as figure 1 As shown, the entire air conditioning and refrigeration equipment includes the following components: compression mechanism 1, first throttling mechanism 5, second throttling mechanism 7, user-side heat exchanger 3, heat source side heat exchanger 4, heater 8, first The flow direction control valve 41 and the second flow direction control valve 42; the first throttling mechanism 5 and the second throttling mechanism 7 are electronic expansion valves; the first flow direction control valve 41 and the second flow direction control valve 42 are electromagnetic valves.

[0034] The connection method of each component of the above air-conditioning and refrigeration equipment is as follows:

[0035] The outlet end of the heater 8 passes through the second throttling mechanism 7 and the sixty-fifth pipe 65 sequentially, and is connected to any one of the two connection ports of the heat source side heat exchanger 4 , and the other connection port of the heat s...

Embodiment 2

[0054] Such as figure 2 as shown, figure 2 The scheme shown is the same as figure 1 The difference in the scheme shown is: figure 1 Compared to the scheme shown, the figure 2 In the shown solution, a four-way valve 2, a second one-way valve 22 and a capillary 12 are added, and at the same time, the first one-way valve 21 is used instead figure 1 The first flow in the illustrated solution is directed to the control valve 41 .

[0055] figure 2 The connection methods of the various components of the air-conditioning and refrigeration equipment shown are as follows:

[0056] The outlet end of the heater 8 passes through the second throttling mechanism 7 and the sixty-fifth pipe 65 sequentially, and is connected to any one of the two connection ports of the heat source side heat exchanger 4 , and the other connection port of the heat source side heat exchanger 4 The connection port is connected to any one of the two connection terminals of the first flow direction con...

Embodiment 3

[0080] Such as image 3 As shown, the whole air-conditioning and refrigeration equipment except comprising embodiment 1 figure 1 In addition to all the components of the shown scheme, a four-way valve 2, a second one-way valve 22, and a third one-way valve 23 are added; in addition, a first one-way valve 21 can be used to replace the first one-way valve. One flow to the control valve 41.

[0081] image 3 The connection methods of the various components of the air-conditioning and refrigeration equipment shown are as follows:

[0082] The outlet end of the heater 8 passes through the second throttling mechanism 7 and the sixty-fifth pipe 65 sequentially, and is connected to any one of the two connection ports of the heat source side heat exchanger 4 , and the other connection port of the heat source side heat exchanger 4 The connection port is connected to any one of the two connection terminals of the first flow direction control valve 41 through the seventieth pipeline 7...

Abstract

The invention discloses air-conditioning and refrigeration equipment. The air-conditioning and refrigeration equipment comprises a compressing mechanism, a user side heat exchanger, a heat source side heat exchanger, a heater, a first throttle mechanism, a second throttle mechanism, a first flow direction control valve and a second flow direction control valve. The outlet end of the heater passes through the second throttle mechanism and a sixty-fifth pipe in sequence and is connected with either of two connection ports of the heat source side heat exchanger. The other connection port of the heat source side heat exchanger is connected with either of two connection end points of the first flow direction control valve through a seventieth pipe. One end of the second flow direction control valve is connected with a pipe between the outlet end of the heater and the second throttle mechanism, and the other end of the second flow direction control valve is connected with the seventieth pipe. The inlet end of the first throttle mechanism is connected with the sixty-fifth pipe through a sixty-sixth pipe. The air-conditioning and refrigeration equipment is simple in structure, reliable in work, low in cost and capable of achieving multiple functions such as refrigeration, heating and hot water production.

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] The invention patent published by the applicant on February 01, 2012 with the application number 201110315796.6, and claim 1 of the invention patent published on April 10, 2013 with the application number 201210028411.2 propose an air-conditioning refrigeration Equipment scheme, its system composition is as follows Figure 6 shown. It can be seen from the description of the above-mentioned invention patent that: Figure 6 The solution shown is capable of multiple functions and is particularly suitable for applications where cooling, heating and domestic hot water are required throughout the year. but from Figure 6 As well as the descriptions of the above two invention patents, it can be known that during operation, Figure 6 The scheme shown suffers from the following drawbacks...
