Described double-tube heat exchanger is to adopt countercurrent heat exchange method, be communicated with by pipeline between the top of this double-tube heat exchanger and the top of attemperater, also be communicated with between the bottom of this double-tube heat exchanger and the bottom of attemperater, and in the connecting pipe of bottom, be provided with circulating electromagnetic valve and water circulating pump successively by pipeline;
The bottom of described double-tube heat exchanger and the connecting pipe between the circulating electromagnetic valve are provided with a pipeline in addition through temperature control electromagnetic and hydraulic pressure sense switch and running water connection;
End is provided with water-level probe on the described attemperater, then is provided with the constant pressure water supply pump with the supply domestic hot-water under the attemperater.
Described blower fan adopts a kind of high-power blower that can regulate power of fan according to environment temperature automatically; Can regulate power of fan automatically according to environment temperature, machine can be moved than state with high energy efficiency.
Described double-tube heat exchanger is the double-tube heat exchanger of countercurrent heat exchange method; Can improve heat exchange efficiency to greatest extent.
When described hydraulic pressure sense switch was a kind of no tap water pressure, air-source water heater can not start, and avoids causing the hydraulic pressure sense switch of dry combustion method.
The attemperater that described attemperater is regulated as the buffering of hot water water consumption; Can control the running of air-source water heater according to the water level upper and lower limit, avoid the air-source water heater frequent starting.
When running water absorbs heat through the double-tube heat exchanger adverse current, directly running water is heated to and flows into behind the design temperature in the insulation buffer tank; The insulation buffer tank is regulated as the buffering of hot water water consumption, and the preferential moisturizing of meeting was restarted water circulating pump, circulating electromagnetic valve to the water level upper limit when buffering water level and water temperature were lower than setting value, and water temperature is to setting value in the heating buffer tank.
When the running of air energy heat exchanger, when finned heat exchanger frosting temperature reaches the defrost temperature of setting, machine is out of service, after about 3 minutes, the defrost magnetic valve is opened, and water circulating pump, circulating electromagnetic valve, compressor start withdraw from when setting value when the defrost temperature rises to, defrost stops, and air can enter the water running state that heats by heat exchanger.
What defrost was adopted is the defrost magnetic valve, and it directly is connected the high-pressure exhaust of compressor and the liquid outlet of throttle capillary tube, directly gives the finned heat exchanger defrost, and simple in structure, fault rate is low, during defrost the hot water water temperature is not had influence.
The invention has the beneficial effects as follows: realized that with rational design directly-heated type produces the hope of high temperature (60 ℃) hot water; When the hot water temperature in the attemperater descends, can heat up automatically according to setting data, guarantee to have at any time the domestic hot-water supply of temperature constant; The constant pressure water supply pump can guarantee constant pressure water supply; Safe and environmentally friendly, long service life.
