All-weather solar and sewage energy mixed auxiliary heat pump water heater system

Abstract

The invention discloses an all-weather solar energy and sewage energy mixed auxiliary heat pump water heater system. The system can furthest utilize solar energy and sewage energy, reduce the utilization of high-grade energy sources, and effectively solve the problem of frosting of a heat pump in winter and has the characteristics of great energy-saving effect, all-weather hot water supply, all-weather heat supply and refrigeration and the like. Not only can water for flushing the toilet and irrigating domestic green plants be saved by collecting domestic miscellaneous sewage, but also abundant cold energy and heat energy contained in the domestic miscellaneous sewage can be effectively utilized, the refrigeration and heating efficiency of the heat pump is increased, and the frosting of the heat pump in winter can be effectively solved. The system can complete the functions of hot water supply, heating and refrigeration of the traditional solar water heater and the heat pump, and saves more energy and can be better adapted to weather change as compared with the traditional solar water heater and the heat pump system.

Description

technical field [0001] The invention relates to a heat pump water heater system, in particular to an all-weather solar energy and sewage energy mixed auxiliary heat pump water heater system. Background technique [0002] At present, among the conventional energy sources used by people, fossil energy occupies a dominant position. But on the one hand, fossil energy is a non-renewable energy source. With continuous consumption, there are less and less fossil energy available for people to use; on the other hand, a large amount of environmentally harmful substances such as carbon dioxide and sulfur dioxide will be produced while using fossil energy. . The harm caused by the use of fossil energy by human society all year round, such as the exhaustion of energy and the deterioration of the environment, has become quite serious. [0003] In this context, solar energy, as a new type of clean and renewable energy, has attracted more and more attention. The total amount of solar en...

AI Technical Summary

Problems solved by technology

[0005] At present, if ordinary solar water heaters want to provide the required hot water around the clock, an auxiliary electric heater must be added, which not only increases the cost, but also reduces its energy-saving benefits.

When ordinary heat pumps are used for heating in winter, for a certain period of time in the middle and lower reaches of the Yangtze River, due to the low outdoor temperature, frost will occur, resulting in insufficient cooling capacity and a decrease in energy efficiency ratio (COP).
