Problems solved by technology

However, it must be pointed out that the simultaneous cooling and hot water heating functions in this invention are essentially to recycle the condensation heat generated in the cooling process to produce hot water, and the amount of hot water depends on the cooling capacity. Therefore, when the above-mentioned air conditioner is used When the amount of hot water is large, or when the cooling capacity is small, the amount of hot water produced by heat recovery during cooling cannot fully meet the needs of users, so in many cases it will affect The normal use of hot water for users; in addition, because the outdoor heat exchanger and the hot water heater of the invention are connected in parallel, therefore, in the process of cooling in summer and part of the heat recovery to produce hot water, it is impossible to obtain higher heat. Water temperature will also cause part of the high-temperature sensible heat in the compressor exhaust to be wasted

Embodiment 1

[0025] Such as figure 1 As shown, the present embodiment is an air-conditioning water heater, which is used in occasions with cooling, heating and hot water demands throughout the year. The whole equipment includes the following components: compression mechanism 1, first four-way valve 70, second four-way valve 80, first throttling mechanism 4, second throttling mechanism 5, user-side heat exchanger 3, heat source side heat exchanger device 6, heater 8, capillary 9, first flow control valve 41, second flow control valve 42, third flow control valve 43, third check valve 23 and fourth check valve 24; 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; the third flow control valve 43 is a solenoid valve.

[0026] The user-side heat exchanger 3 acts as an evaporator in summer to cool users, and in winter as a condenser to provide heating for users; The evaporator ...

Embodiment 2

[0059] Such as Figure 4 As shown, the present embodiment is also an air-conditioning water heater, which is used in occasions with cooling, heating and hot water demands throughout the year. The difference with Embodiment 1 is that a liquid reservoir 50 is added in the system, and its connection mode is: the second throttling mechanism 5 is connected with the liquid reservoir 50 through the fifty-sixth pipeline 56, and the outlet port of the fourth one-way valve 24 The sixty-eighth pipeline 68 is connected to the liquid reservoir 50, one end of the third flow direction control valve 43 is connected to the fifty-fourth pipeline 54, and the other end of the third flow direction control valve 43 is connected to the liquid reservoir 50 through the fifty-fifth pipeline 55. , the fifty-sixth pipeline 56 or any one of the sixty-eighth pipelines 68 is connected. Figure 4 As shown, the fifty-fifth pipeline 55 in this embodiment is connected to the liquid reservoir 50.

Embodiment 3

[0067] Such as Figure 5 As shown, the present embodiment is also an air-conditioning water heater, which is used in occasions that require cooling, heating and hot water throughout the year. The difference from Embodiment 1 is that a third throttling mechanism 7 is added to the system, and its connection mode is: one end of the third throttling mechanism 7 is connected to the heater 8, and the other end of the third throttling mechanism 7 passes through the fifty-second The pipeline 52 is connected with the first throttling mechanism 4 and the fifty-fourth pipeline 54 at the same time. Such as Figure 5 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.

[0068] Their connection mode is: the inlet port of the first check valve 21 is connected with the sixty-first pipeline 61, the outlet port of the first check valve 21 is connected with the h...

Description

technical field [0001] The invention relates to a multifunctional air-conditioning water heater and belongs to the technical field of refrigeration. Background technique [0002] The invention patent with the patent number of 200710026952.0 relates to a multi-functional heat pump hot water multi-connected air conditioner, which has five functions: separate cooling, separate heating, separate heating of hot water, simultaneous cooling and heating of hot water, and simultaneous heating and heating of hot water. function. However, it must be pointed out that the simultaneous cooling and hot water heating functions in this invention are essentially to recycle the condensation heat generated in the cooling process to produce hot water, and the amount of hot water depends on the cooling capacity. Therefore, when the above-mentioned air conditioner is used When the amount of hot water is large, or when the cooling capacity is small, the amount of hot water produced by heat recover...
