Technical field
The present invention relates to a kind of air heat source and thermal pump water heater, refer in particular to a kind of double-water-tank system air source heat pump water heater.
Technical background
At present the water heater of generally selling on China air source hot pump water heater market is mainly two kinds of single cistern system and double-water-tank systems.Wherein, the control of stainless steel floating ball valve is adopted in single cistern system water heater water inlet usually, when water tank water is discontented with, ball-cock assembly is opened moisturizing, and the completely back ball-cock assembly of water tank water is closed and stopped moisturizing, need not the auxiliary control of other any parts, structure is simpler relatively, and cost is with low cost.But, when the client uses hot water, cold water is along with the reduction of ball float covers automatically, many more along with client's hot water consumption, cold water covers many more, thereby cause the coolant-temperature gage in the heating water tank to reduce gradually, suppose that water tank initial hot water temperature is 55 ℃, the running water water temperature is 15 ℃, and when the client had used 50% hot water, cold water had also advanced 50%, hot and cold water mixes the rear water box water temperature and has only 35 ℃, 35 ℃ of water are lower than people's body surface temperature generally speaking, can't satisfy client's instructions for use, and the hot water availability is lower; And common double heating water tank system water heater is made up of a heating water tank and an attemperater, usually it is smaller to go up heating water tank on the market, attemperater is bigger, unit is earlier to little water tank heating, water is pumped to attemperater after being heated to design temperature, after attemperater water need not be lowered the temperature for a long time, again water is drawn back heating water tank and heat, or heating water tank is placed on the deadweight inflow attemperater that the attemperater top relies on water.Send water between two water tanks, the backwater that reaches post bake all needs pump working to realize, the installation cost height is many owing to water pump on the other hand on the one hand, the reliability reduction, and power consumption is big; Water pump is delivered to attemperater during this period of time with water from heating water tank in addition, and unit is not worked, and produces the hot water time to be wasted.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art, a kind of double-water-tank system air source heat pump water heater is provided, it has reduced the operating temperature point and the power consumption of unit effectively, has improved the COP value of unit.
For achieving the above object, the solution that the invention is taked is: a kind of double-water-tank system air source heat pump water heater, it comprises the main frame that contains refrigeration system, heating water tank, attemperater and controller, the heating water tank top and the bottom are adorned the first high water level switch and first low-water level switch respectively, built-in heating water tank temperature sensor, the attemperater top and the bottom are adorned the second high water level switch and second low-water level switch respectively, built-in heat insulation water tank temperature sensor, connect between heating water tank and the attemperater second magnetic valve and the 3rd magnetic valve, connect target stream switch on the pipeline of main frame right side, second butterfly valve, be connected between second magnetic valve and the 3rd magnetic valve by the 5th ball valve, main frame left side pipeline is by second water circulating pump, water filter, connect first butterfly valve and by connecing heating water tank by the 5th magnetic valve respectively behind the 4th ball valve and by the 4th magnetic valve, second check-valves connects attemperater, water meter, first magnetic valve, first ball valve, the water charging system that first check-valves is formed also connects heating water tank, the 4th magnetic valve, second ball valve, the water system that the 3rd ball valve is formed connects attemperater, the main frame and second magnetic valve, the 3rd magnetic valve, the 4th magnetic valve, the 5th magnetic valve, second check-valves is formed hot water cyclesystem, heating water tank, the first high water level switch, first low-water level switch, the heating water tank temperature sensor, attemperater, the second high water level switch, second low-water level switch, the attemperater temperature sensor is formed water storage system, the 4th ball valve, the 5th ball valve, first butterfly valve, second butterfly valve, second water circulating pump, target stream switch is formed purging system.
The utility model has utilized the water circulating pump of unit self dexterously, need not to add water circulating pump and just water can be delivered to attemperater, and construction costs is low; When same temperature hot water was provided, the unit actual work temperature had been than normally just making low 5 ℃ of temperature, thereby reduced the operating temperature point of unit effectively, reduced the power consumption of unit, improved the COP value of unit.Be a kind of have applied widely, reliability is high, the round-the-clock hot water supply system of advantage such as energy-conservation.
The present invention gathers high and low water level switch and water tank temperature in the target in hot water circulating pipeline stream switch and heating water tank, the attemperater by controller, the temperature of hot water and water level in the real-time judge water tank are controlled system effectively to water circulating pump, magnetic valve, main frame.Elder generation mends cold water by first magnetic valve (entering water electromagnetic valve) to heating water tank, and when water level arrived low-water level switch, second water circulating pump started, and moves 2 minutes and later on target stream switch is detected, and is closed as water flow switch, then starts main frame; When water level was elevated between low-water level switch and the high water level switch, the first magnetic valve start and stop were controlled according to the heat storing and heat preserving water tank temperature.When water temperature in the heating water tank was heated to than low 5 ℃ of design temperature, second magnetic valve (heating water tank magnetic valve) cut out, and the 3rd magnetic valve (attemperater magnetic valve) is opened, and hot water is delivered to attemperater.When the water level in the heating water tank is lower than low-water level switch, the 3rd closed electromagnetic valve then, second magnetic valve starts, and carries out the moisturizing heating again.If the hot water in the attemperater does not use for a long time, then close second magnetic valve, open second magnetic valve, give the heating of the water in the attemperater by main frame.Guaranteed that unit works under low-power consumption, thereby the round-the-clock hot water that provides has been provided.
