Fig. 2 is a control strategy waterline of the present invention.
The specific embodiment
Below in conjunction with drawings and Examples technical scheme of the present invention is described further:
As shown in Figure 1, this invention is made up of hot water storage tank, heating thermal source, heat pump, cesspool, heat exchanger, feed pump, sewage pump, filter and valve etc.
Cesspool comprises two-way output, and a route the 4th valve F4 control directly enters sewer; An other route the 3rd valve F3 control earlier through behind the filter, enters heat exchanger by the sewage pump pressurization again, enters sewer after entering the evaporator with heat pump heat exchange then.
Tap water pipe line is divided into two-way, and one the road often supplies the bathroom, and an other route first valve F1 control by entering heat exchanger after the feed pump pressurization, enters the heat pump condenser heat exchange more then, enters hot water storage tank again.
The water inlet pipe of hot water storage tank is connecting the outlet pipe of heat pump, and the hot water that heat pump produces enters hot water storage tank.Water outlet is divided into two-way, and one road hot water often supplies the bathroom, and other one road hot water is controlled by the second valve F2, directly incorporates the running water pipe of entrance of water-supplying pump into.
Hot water storage tank comprises the heating thermal source, and this thermal source can be various forms of boilers, solar heater or other forms of thermal source, can independently select according to actual conditions, is mainly used in heating when starting.
Control strategy can adopt the water level control in hot water storage tank and the cesspool, and the water level control line as shown in Figure 2.Wherein hot water storage tank control comprises two control line V1 and V2, and cesspool comprises four control line V3, V4, V5 and V6.
When bringing into operation, there is not water in the cesspool.This moment, the first valve F1 opened, and the second valve F2, the 3rd valve F3 and the 4th valve F4 close, and heat pump cuts out, and running water through heat exchanger, heat pump, enters hot water storage tank after being pressurizeed by feed pump then, used by sending into the bathroom after the heating of heating thermal source.
