Description

Technical Field

[0001] The invention relates to the technical field of heat pump water heating equipment, and in particular to an intelligent multi-source heat pump water heating device. Background Art

[0002] Heat pump is a highly efficient energy-saving device that makes full use of low-grade thermal energy. There are many kinds of heat sources for heat pumps, among which air source and geothermal source are commonly used. Heat pumps utilize the heat in air or geothermal to achieve the purpose of energy saving. However, with the increasing use of heat pumps, the use of one heat source is no longer sufficient to meet the needs of users in different regions.

[0003] Existing solar energy can assist air source heat pumps. The refrigerant, as a solar heat collection medium, directly absorbs heat and evaporates in the solar heat collector / evaporator, and then releases the condensation heat to the heated object through the heat pump cycle. Due to the intermittent nature of solar radiation, the performance of this system fluctuates greatly. Solar energy is used as a low-quality heat source for the heat pump system. The use of solar energy requires the heat pump system to consume electricity to further improve the quality, and it is impossible to improve the performance of the heat pump system with solar energy.

[0004] Therefore, how to organically combine solar energy with air source heat pumps, solve the stability of the solar-assisted air source heat pump system, and fully and efficiently utilize solar energy has become a technical problem that technical personnel in this field urgently need to solve. To this end, an intelligent multi-source heat pump hot water device is proposed. Summary of the invention

The low-heat medium can be compressed into high-temperature and high-pressure gas by the compressor 7 and enter the condenser 8. The condenser 8 can exchange heat with the water inside the condensing chamber 4, so as to heat the water inside the condensing chamber 4 for use. The heated water can be used for daily life of users. The medium flowing out of the condenser 8 can be reduced in pressure through the expansion valve 11 and flow back to the inside of the evaporator 6, absorb external heat, and transfer heat to the tap water inside the condensing chamber 4. Compared with heating with an electric heater alone, it is more energy-saving, faster and safer, and the outdoor thermal energy potential is unlimited. Low-temperature thermal energy can be provided by external solar energy, underground thermal energy, etc., which can meet the normal use of various regions in low-temperature areas.

[0024] Specifically, the input end of the compressor 7 is connected to the output end of the evaporator 6 through a connecting pipe, the output end of the liquid storage tank 9 is connected to the input end of the filter 10 through a connecting pipe, the output end of the filter 10 is connected to the input end of the expansion valve 11 through a connecting pipe, and the output end of the expansion valve 11 is connected to the input end of the evaporator 6 through a connecting pipe. The evaporator 6, the compressor 7, the liquid storage tank 9, the filter 10 and the expansion valve 11 can form a complete function of the heat pump, so that the heat pump can be operated and used.

[0025] Specifically, the condenser 8 is composed of a condensation pan 801, a condensation tube 1 802 fixedly installed at the input end of the condensation pan 801, and a condensation tube 2 803 fixedly installed at the output end of the condensation pan 801. The condensation pan 801 is an S-shaped structure, and a heat exchange cavity 805 is formed inside the condensation pan 801.

[0027] Working principle: First, the heat flux plate heating component can be connected to the solar panel externally or to the soil, and conduct heat through the medium inside the pipeline. The heat energy can be conducted to the evaporator 6 located inside the heat pump box base 1 through the heat exchange tube disc 15, which is used to provide low heat capacity. The evaporator 6, the compressor 7, the liquid storage tank 9, the filter 10 and the expansion valve 11 can form a complete function of the heat pump, so that the heat pump can be operated. The low heat medium can be compressed into high-temperature and high-pressure gas by the compressor 7 and enter the condenser 8. The high-temperature and high-pressure gas compressed by the compressor 7 can be heated with the water inside the condensation chamber 4 through the condenser tube 802 first, and the gas medium flowing through the condenser tube 802 can subsequently enter the heat exchange chamber 805.
