Circulating and energy-saving water heater set of solar heat pump

Abstract

The invention provides a circulating and energy-saving water heater set of a solar heat pump. The circulating and energy-saving water heater set of the solar heat pump comprises an air source heat pump set, a circulating pump, an electromagnetic valve, an exhausting pipe, a water tank, a bath water supplying pump, a sewage source heat pump set, a bath waste water pool, a temperature sensor and a solar water heater. The air source heat pump set comprises a fan, an evaporator I, a compressor I, a condenser I, a liquid storage pot, a filter and an expansion valve I; the water tank comprises a water level sensor and a temperature sensor I; the sewage source heat pump set comprises a condenser II, an expansion valve II, an evaporator II and a compressor II. The bath waste water pool comprises a temperature sensor II and a sewage water heat taking and exchanging device; the solar water heater comprises a temperature sensor III and an exhausting pipe II. The circulating and energy-saving water heater set of the solar heat pump is wide in application range, easy to install in a matched mode and capable of enabling the energy-saving efficiency to be doubled.

Description

technical field [0001] The invention belongs to solar heat pump energy-saving hot water equipment, in particular to a solar heat pump cycle energy-saving hot water unit. Background technique [0002] At present, the development and utilization of solar energy has been widely valued. There are many types and forms of solar water heaters. However, the main problem of existing solar water heaters is that there are few heat collectors suitable for high-latitude cold regions in winter, and there are not many related researches. The temperature in the area is low, the loss of heat dissipation is large and there is a phenomenon of freezing damage. Generally, solar water heaters are not used in winter, and there is no hot water supply in cloudy days and no sunshine in other seasons, which brings great inconvenience to users and reduces the efficiency of solar energy. high. How to guarantee people's demand for hot water in daily life, economical and practical, has become a technica...
