Description
One. technical field
The present invention relates to a kind of recuperation of heat and join the heat exchange water source heat pump water heater more.
Two. background technology
The widely used hot water mode of heatings of industry such as home and abroad cosmetology, foot care, bathing are combustion gas, fuel oil, electrical heating, solar energy, air source heat pump etc. at present; At also useful water source, area that geographical conditions allow, earth source heat pump, but the user is seldom.Former three is because use cost is high, and though the not very willing usefulness of user is energy-conservation, the power saving of solar water heater among the latter; But in winter or when overcast and rainy; The hot water temperature is on the low side can't normally to be used, if use auxilliary electrical heating cost high again, and not so good the using in few area of sunshine-duration.Air source hot pump water heater is more energy-conservation, but under the situation of, high humidity low in environment temperature, the Energy Efficiency Ratio of heat pump reduces, and the user can't normally use.So the user of many air source hot pump water heaters can adopt other mode of heatings to replenish winter, has so both increased the overlapping investment of user to hot water facility, has strengthened user's use cost again.Though water resource heat pump, high, the working stability of earth source heat pump Energy Efficiency Ratio are owing to receive the restriction of geography, environmental condition seldom to have the user to use.
There is a problem in general of at present domestic in addition Teat pump boiler, is exactly that because the working medium temperature that from condenser, flows out, pressure was higher, and Compressor Discharge Pressure is increased after water temperature was higher than 55 degree Celsius, and compressor load increases the weight of, and the danger that burns out compressor is arranged.
Three. summary of the invention
The situation lower water-heater of, high humidity low in environment temperature in order to solve can operate as normal, the invention provides a kind of can be low in environment temperature, the recuperation of heat of operate as normal joins the heat exchange water source heat pump water heater more under the situation of high humidity.
The technical solution adopted for the present invention to solve the technical problems is: at first to the water in the hot water reserve tank; Make it reach that temperature (about 60 degree Celsius) is set is subsequent use through electric hot plate heating; The user is when using hot water; The used spent hot water of user is gathered, filters, reclaims, and store the water-supply source heat pump with spent hot water's reserve tank thermal source is provided.The secondth, a heat recovering heat exchanger (water, water-to-water heat exchanger) is set in water-heater system, the spent hot water and the supplementing water of gathering are carried out heat exchange therein, improve the temperature of supplementing water, reduce the working application time of heat pump.The 3rd is between condenser and flow controller, to be provided with one to attach condenser; The higher working medium of the temperature that from condenser, flows out is carried out heat exchange with supplementing water in attaching condenser; Reduce the working medium temperature, the pressure that get into flow controller, reduce the load of compressor, improved the supplementing water temperature that gets into the hot water reserve tank simultaneously; Reduce the heat pump working application time, practiced thrift electric energy.
The thermal source that the present invention adopts is just used spent hot water, does not receive the influence of environment, even under extreme climate environment (about subzero 10--30 degree), as long as it is normal to supply water, just can normally use.Because the present invention is provided with one and attaches condenser between flow controller and condenser, even when the coolant-temperature gage of water heater is spent up to Celsius 65, compressor also can be normally, trouble free service.The present invention has adopted repeatedly heat exchange to the spent hot water, has improved the Energy Efficiency Ratio of water heater greatly, makes the present invention than traditional energy-conservation 30-50% of all Teat pump boilers, greatly reduces user's use cost.
