the second outlet of the first three-way pipe 23 is connected with the inlet of the radiator 29 through a second water pump 27, a second valve 28 and a second inlet of the second three-way pipe 24, and the outlet of the radiator 29 is connected with the second inlet of the second three-way pipe 24.
The enhanced combined set 1 comprises a first condensation heat exchanger 11, a first outlet of the first condensation heat exchanger 11 is connected with an inlet of a compressor 12, an outlet of the compressor 12 is connected with a first inlet of a heat pump option box 21, a first outlet of the heat pump option box 21 communicated with a first inlet of the heat pump option box 21 is connected with an inlet of an expansion valve 13, an outlet of the expansion valve 13 is connected with a first inlet of the first condensation heat exchanger 11, and a first inlet of the first condensation heat exchanger 11 is communicated with a first outlet of the first condensation heat exchanger 11.
Referring to fig. 2, the heat pump option box 21 is composed of the second condensing heat exchanger 211, the first plate heat exchanger 212 and a box body, and interfaces are formed on the box body, so that the interfaces of the second condensing heat exchanger 211 and the first plate heat exchanger 212 in the box body can be matched with the interfaces on the box body, and thus, the heat pump option box is easy to install, and a user can use the corresponding heat exchanger in the box body only by connecting the pipeline with the corresponding interface outside the box body.
The working principle of the invention is as follows:
generally, the basic heat pump unit 2 is sufficient to meet the living needs of a family, at this time, a user needs to connect a related pipeline with the second condensing heat exchanger 211 in the heat pump option box 21, smoke gas flows in from the second inlet of the heat pump option box 21, heat exchange is realized between the smoke gas and a circulating working medium in the second condensing heat exchanger 211 in the heat pump option box 21, then the smoke gas flows out from the second outlet of the heat pump option box 21, then a high-temperature circulating working medium flows to the first three-way pipe 23 under the action of the first water pump 22, flows to the first valve 25 after being shunted by the first three-way pipe 23, and simultaneously flows to the second valve 28 under the action of the second water pump 27, at this time, the user can independently select whether the circulating working medium flows to the second plate heat exchanger 26 and the radiator 29 or not by opening and closing the first valve 25 and the second valve 28, and assuming the situation of simultaneous heating, at this time, the high-temperature circulating control respectively flows to the second plate heat exchanger 26 and the radiator 29, the high-temperature circulating working medium in the second plate heat exchanger 26 exchanges heat with low-temperature domestic water to provide domestic hot water for the residents, and the other part of the high-temperature circulating working medium flows into the radiator 29 to provide heating for the residents; then, the low-temperature circulating working medium is gathered together through the second three-way pipe 24 and flows into the first plate heat exchanger 21 again, and then exchanges heat with the flue gas again, so that one circulation is realized.
In practical situations, the heat exchange efficiency is insufficient due to various reasons, so that the heating condition of 'no power supply' is caused, at the moment, a resident can install an enhanced union by himself, the resident only needs to detach the pipeline connected with the second condensing heat exchanger 211 in the original heat pump option box 21 and connect the pipeline with the first plate heat exchanger 212, then the first inlet of the heat pump option box 21 is connected with the outlet of the compressor 12, the first outlet of the heat pump option box 21 is connected with the inlet of the expansion valve 13, and simultaneously the outlet and the inlet of the first condensing heat exchanger 11 are respectively connected with the inlet of the compressor 12 and the outlet of the expansion valve 13. At this time, the flue gas does not flow through the second condensing heat exchanger 211 but flows into the first condensing heat exchanger 11, the flue gas and the circulating working medium in the enhanced combined set 1 complete heat exchange in the first condensing heat exchanger 11, then flows into the compressor 12, the circulating working medium is changed into a high-temperature high-pressure circulating working medium by the work of the compressor 12, then the high-temperature high-pressure circulating working medium flows into the heat pump selection box 21, exchanges heat with the low-temperature circulating working medium in the basic heat pump combined set 2 in the first plate heat exchanger 212 in the heat pump selection box 21, because the common high-temperature circulating working medium is changed into the high-temperature high-pressure circulating working medium, the heat exchange efficiency is greatly improved, the circulating working medium in the enhanced combined set 1 is changed into the low-temperature high-pressure circulating working medium after realizing heat exchange, flows into the expansion valve 13, and is changed into the low-temperature low-pressure circulating working medium again to flow back into the first condensing heat exchanger 11 to exchange heat with the flue gas again under the action of the expansion valve 13, thereby realizing one cycle in the enhanced team 1. The flue gas exchanging heat with the circulating working medium in the basic heat pump unit 2 is replaced by the high-temperature and high-pressure circulating working medium in the enhanced unit 1 with higher actual heat exchange efficiency, and the circulating process is the same as the mode, so that the heat exchange efficiency of the whole heat pump unit is improved, and heat supply is more powerful.
The multifunctional assembled split heat pump with the enhanced union can supply heat for different heat utilization equipment respectively or simultaneously according to the requirements of users, the heat exchange efficiency can be improved by installing the enhanced union under the condition of basically not changing a circulation mechanism, and the heat pump selection box is arranged to allow the users to select to access the condensing heat exchanger or the plate heat exchanger, so that the installation process is simplified, and the users are given higher autonomy. Therefore, the whole heat pump unit can give a lot of force flexibly, and has great environmental adaptability as an energy recycling device, the comprehensive COP of the whole system is improved to a great extent, and the requirement of a user can be met to a greater extent.
