Description

A kind of novel air source heat pump solar water heater

Affiliated technical field

The utility model relates to a kind of solar water heater that utilizes the auxiliary heating of air energy heat pump water heater, is not that very regular situation is issued to same heat supply water and energy-conservation effect at rainy weather or water consumption especially.

Background technology

At present, known solar water heating system is to gather solar heat heating cold water by solar thermal collector, utilizes the heat insulating bucket stored hot water, and the electrothermal tube heating is directly adopted in the auxiliary heating when rainy weather.Yet the thermal efficiency of electrothermal tube is very low, can not satisfy requirements of saving energy.

Also there is the part solar water heater that heat-exchange device directly is installed in water tank, heating in the working medium introducing warming solar energy water tank of heat pump carried out heat exchange, leak working medium during installation easily, very high to installation specification.

Summary of the invention

The purpose of this utility model provides a kind of follow-on solar water heating system, having has the solar time to utilize the energy of the sun, utilize high efficiency air source heat pump to heat during rainy weather, and improved mounting means, adopt the control of intelligent temperature water level sensory perceptual system, can both provide the hot water that is fit to temperature in 24 hours.

To achieve these goals, the utility model provides a cover follow-on solar water heating system, by solar energy heat collection pipe, attemperater, air source heat pump heat-producing machine, a multisection type level switch, a multipoint mode Temperature Detector, a Comprehensive Control main frame is formed.

The heat exchanger of air source hot pump water heater is located at the inside of air source hot pump water heater, and attemperater adopts the hot water water pipe to be connected with the air source heat pump heat-producing machine.

Multisection type level switch of attemperater interior arrangement can be measured the variation of water level positive and negative 10%.

Multipoint mode Temperature Detector of attemperater interior arrangement detects inflow temperature respectively, leaving water temperature and water tank internal temperature.

The Comprehensive Control main frame is by bus mode and level switch, and Temperature Detector connects, and water level and temperature are monitored.

The Comprehensive Control main frame electrically connects water inlet control magnetic valve, and inflow is controlled.

The Comprehensive Control main frame electrically connects the start-stop of air energy heat pump water heater.

The Comprehensive Control main frame also plays the monitoring effect, the compressor operate as normal of protection air energy heat pump water heater to the various duties of air energy heat pump water heater.

The utlity model has following beneficial effect: the attemperater of solar water heater adopts the hot water water pipe to be connected with the air source heat pump heat-producing machine, has lowered the complexity of installing, and leaks working medium when stopping owing to installation, has reduced cost.Rainy weather can provide hot water equally, and when water consumption exceeded the capacity of attemperater of solar water heater, the Comprehensive Control main frame can carry out intelligence adjusting inflow, heat time heating time with temperature according to the water yield of the attemperater inside of the solar water heater of gathering.
