Self-supply type water source heat pump water heating energy-saving system and intelligent control method

Abstract

The invention discloses a self-supply type water source heat pump water heating energy-saving system and an intelligent control method. An intermediate water tank provides a circulating water source for a water source heat pump. By means of a double-effect solar heat exchanger, by utilizing the advantage of large heat exchange area of a solar heat collector, the method of intelligently comparing temperatures and water levels and utilizing different heat sources by intelligent identification is adopted; when sunlight is sufficient, finished-product hot water heat energy is directly provided; when the sunlight is insufficient or no sunlight exists, an integrated type forced ventilation heat exchange system is utilized to raise water resource temperature, and a continuous heat source is provided for the water source heat pump. The self-supply type water source heat pump water heating energy-saving system effectively solves the problem that a traditional water source heat pump cannot be used under the condition that no large-area clean water source exists or under the condition that the water source cannot continuously provide heat energy, and the problem that medium-grade solar energycannot be used since the medium-grade solar energy cannot heat water to the temperature required by a user, and then resource waste is caused is also solved; the self-supply sustainable use type water source and heat source are provided for the water source heat pump, and the use cost of hot water is greatly saved for the user. The self-supply type water source heat pump water heating energy-saving system can be widely applied to water heating energy saving field.

Description

technical field [0001] The invention relates to a self-supporting water source heat pump hot water energy saving system and an intelligent control method, and relates to the technical fields of utilization of renewable energy and hot water energy saving. Background technique [0002] At present, schools, guesthouses, hotels, factories and other places need a large amount of domestic hot water at about 50°C. Due to the long average sunshine time of solar energy in my country and abundant solar energy resources, solar water heaters have been widely used in the above places. In addition, due to the high annual average temperature in large areas of my country, such as the average temperature in South China (Guangdong, Guangxi, Guizhou, Yunnan, Hainan, etc.) above 22°C, air-energy heat pumps are also widely used, and air-energy heat pumps are used as an auxiliary for solar hot water The heating system, a good combination of the two, can ensure the supply of hot water for users all...

AI Technical Summary

Problems solved by technology

The invention effectively solves the situation that the traditional water source heat pump cannot be used when there is no large-area clean water source or the water source cannot continuously provide heat energy, and at the same time solves the problem that the mid-grade solar energy cannot be used when the water temperature meets the user's requirements, resulting in waste of resources. The heat pump provides a self-sufficient, sustainable water source and heat source, saving users a lot of hot water usage costs
