Description

Technical Field

[0001] This utility model relates to a device for coupling a centralized heating system and a water heat pump. Background Technology

[0002] The existing technology, Chinese patent 202410794845.6, describes an indoor return water heating enhancement machine for centralized heating, which includes a water supply pipeline, a return water pipeline, a heating terminal, and a water source heat pump heating unit. The heating terminal includes a manifold and at least one sub-heating terminal. The water supply pipeline and the return water pipeline are respectively connected to the inlet and return water ends of the heating terminal. The water heat exchanger section of the water-side heat exchanger is connected in series or parallel to the pipeline at the return water end of the heating terminal; or the heating terminal includes several sub-heating terminals, which are respectively connected to the water supply pipeline and the return water pipeline. The water heat exchanger section is connected in series or parallel to the return water pipeline. One sub-heating terminal and one water source heat pump heating unit constitute a group. The return water pipe at the heating terminal of the centralized heating system is connected to the water source heat exchanger of the water source heat pump heating unit. When the indoor temperature drops, or the system pressure is low and circulation is slow, causing a drop in indoor temperature, the water source heat pump heating unit operates, absorbing the heat energy from the return water in the return pipe to supplement the indoor temperature by either raising or maintaining it. The problem is that the water source heat pump system and the centralized heating system are not coupled together. Utility Model Content

[0021] Example 1

[0022] like Figure 1 As shown, a water-source heat pump coupled with a water-collecting heating system includes a centralized heating system, comprising a centralized water supply pipe 1 and a centralized water return pipe 2, heating terminals 3, terminal return pipes 4, a condensing dual-channel heat exchanger 51, an evaporating dual-channel heat exchanger 52, a compressor 6, and a one-way valve 7.

[0023] The condensing dual-channel heat exchanger 51 includes a condensing refrigerant channel and a first water channel, and the evaporating dual-channel heat exchanger 52 includes an evaporating refrigerant channel and a second water channel.

[0024] The centralized water supply pipe 1, the first water channel of the condensing dual-channel heat exchanger 51, the heating terminal 3, the terminal return water pipe 4, and the centralized return water pipe 2 are connected in sequence. The centralized water supply pipe 1, the second water channel, the one-way valve 7, and the centralized return water pipe 2 are also connected in sequence. With this structure, when the weather is normal or the indoor temperature is comfortable, the centralized water supply pipe 1, the first water channel of the condensing dual-channel heat exchanger 51, the heating terminal 3, the terminal return water pipe 4, and the centralized return water pipe 2 are connected in sequence to form a self-heating state.

[0025] When the weather is abnormal or the indoor temperature needs to be raised, the water source heat pump system works. The evaporating refrigerant channel of the evaporating dual-channel heat exchanger 52 exchanges heat with the hot water in the centralized water supply pipe; the condensing refrigerant channel of the condensing dual-channel heat exchanger 51 heats the hot water from the centralized water supply pipe, further increasing the temperature, and then enters the heating terminal 3 to quickly raise the indoor temperature.

[0026] Example 2

[0027] like Figure 2 As shown, it also includes an electric two-position three-way valve 8;

[0028] The electric two-position three-way valve 8 is connected to the centralized water supply pipe 1, the terminal return water pipe 4, and the second water flow channel.

[0029] The centralized water supply pipe 1, the CB end of the electric two-position three-way valve 8, the second water flow channel, the one-way valve 7, and the centralized return water pipe 2 are connected in sequence. In this way, the evaporative dual-channel heat exchanger 52 of the water source heat pump system directly exchanges heat with the hot water in the centralized water supply pipe, thereby achieving rapid indoor heating.

[0030] Alternatively, the heating terminal 3, the AC end of the electric two-position three-way valve 8, the second water flow channel, the one-way valve 7, and the centralized return water pipe 2 are connected in sequence;

[0031] In this way, the evaporator dual-channel heat exchanger 52 of the water source heat pump system exchanges heat with the return water flowing out of the heating terminal; the two methods in this embodiment can be switched.

[0032] Example 3

[0033] like Figure 3 As shown: It also includes an electric four-way valve 9.

[0034] The electric four-way valve 9 is installed on the end return water pipe 4 and is connected to the second water flow channel and the centralized water supply pipe 1.

[0035] like Figure 3 As shown, the centralized water supply pipe 1, the AC end of the four-way valve, the second water flow channel, the one-way valve 7 and the centralized return water pipe 2 are connected in sequence, and the centralized water supply pipe 1, the first water flow channel, the heating terminal 3, the BD end of the four-way valve, the heating return water pipe 4 and the centralized return water pipe 2 are connected in sequence.

[0036] Hot water from the centralized water supply pipe 1 is used as the heat source for the water source heat pump system.

[0037] like Figure 4 As shown, the centralized water supply pipe 1, the AD end of the four-way valve and the centralized return water pipe 2 are connected in sequence, and the centralized water supply pipe 1, the first water flow channel, the heating terminal 3, the BC end of the four-way valve, the second water flow channel, the one-way valve and the centralized return water pipe 2 are connected in sequence.

[0038] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
