Embodiment 1
[0022] Such as figure 1 As shown, this embodiment is an air-conditioning and refrigeration device with multiple functions, which is used in occasions that require cooling, heating and domestic hot water throughout the year. figure 1 The air-conditioning and refrigeration equipment shown includes the following components: compression mechanism 1, four-way valve 2, first throttling mechanism 5, second throttling mechanism 7, user-side heat exchanger 3, heat source-side heat exchanger 4 and hot water Heater 8; the first throttling mechanism 5 and the second throttling mechanism 7 are electronic expansion valves; the user-side heat exchanger 3 is a refrigerant-water heat exchanger, which is used for producing chilled water in summer and for production in other seasons Hot water; the heat source side heat exchanger 4 is a refrigerant-air heat exchanger, which can be used as a condenser to dissipate the condensation heat generated by refrigeration to the environment, or as an evapor...
Embodiment 2
[0059] Such as figure 2 As shown, it is the same as Example 1 figure 1 The difference of the shown solution is that a liquid reservoir 9 and a fourth one-way valve 24 are added in the air-conditioning and refrigeration equipment.
[0060] Such as figure 2 As shown, the connection mode of the liquid reservoir 9 and the fourth one-way valve 24 in the air-conditioning and refrigeration equipment is: the inlet port of the fourth one-way valve 24 is connected with the inlet port of the second one-way valve 22 and the heat source through the sixty-sixth pipeline 66 The 70th pipeline 70 at the outlet end of the side heat exchanger 4 is connected, and the outlet end of the fourth one-way valve 24 passes through the 67th pipeline 67, the liquid reservoir 9, the 65th pipeline 65, the first throttling mechanism 5 and the The sixty-second pipeline 62 is connected.
[0061] This embodiment figure 2 The scheme shown, and its matching image 3 The air-conditioning and refrigeration e...
Embodiment 3
[0066] Example 1 figure 1 and Example 2 figure 2 The scheme can be further improved by adding an oil separator 90 in the air-conditioning and refrigeration equipment. At this time, the connection mode of the oil separator 90 in the air-conditioning and refrigeration equipment is: the inlet port of the oil separator 90 and the compression mechanism 1 The outlet end is connected, and the outlet end of the oil separator 90 is connected with the high pressure node 71 of the four-way valve 2 through the sixtieth pipeline 60 .
[0067] During operation, the function of the oil separator 90 is to separate oil from the exhaust gas of the compression mechanism 1 . The scheme described above in this embodiment is applicable to the schemes described in all embodiments of the present invention.
