Such as Fig. 1, shown in 2, a kind of instant heating type heat pump type water heater, including small-sized water tank 1, cistern assembly, air source heat pump system, control system and protection device etc..
Small-sized water tank 1 connects air source heat pump system by pipeline, and water in small-sized water tank is heated by air source heat pump system, for reducing the power consumption of Water heater for kitchen, extends and the hot water time, improves Water heater for kitchen utilization rate；It is internal that cistern assembly includes that small-sized water tank, limnimeter, temperature sensor 6, limnimeter and temperature sensor 6 are positioned over small-sized water tank 1, is respectively intended to detect the water level in small-sized water tank 1 and water temperature；Electromagnetic valve is arranged on small-sized water tank inlet pipeline；Temperature sensor 6 is connected air source heat pump system by control system with protection device, and when tested water temperature is less than set water temperature, control system and protection device start air source heat pump system and run.
As shown in Figure 1, small-sized water tank 1 is connected in series with air source heat pump system, and wherein, the condenser 2 in air source heat pump system is placed in small-sized water tank 1, the coil outlets of condenser 2 passes sequentially through throttling arrangement 4, vaporizer 5, compressor 3 connect the coil pipe import of condenser 2, forms heating circuit.
As shown in Figure 2, small-sized water tank 1 is connected in parallel with air source heat pump system, wherein, condenser 2 in air source heat pump system is placed in outside small-sized water tank 1, it is provided with cold water inlet bottom described small-sized water tank 1, water inlet connects current equalizer 7, the cold water within the small-sized water tank of entrance 1 is made to be internally formed thermally stratified layer at small-sized water tank 1, small-sized water tank 1 top is provided with hot water outlet, hot water outlet connects a water inlet of water mixing valve A, another water inlet of water mixing valve A connected condenser 2 and connected water pump P outlet, the outlet of condenser 2 passes sequentially through compressor 3, vaporizer 5, throttling arrangement 4 connects the import of condenser 2, form heating circuit；When small-sized water tank 1 water temperature inside is less than setting value, air source heat pump system starts, and water mixing valve A and water pump P are run, and the hot water making user be used is supplied simultaneously to by small-sized water tank 1 and air source heat pump system.
The volume scope of small-sized water tank 1 is 1-20L.Condenser 2 is condenser coil or double pipe heat exchanger or plate type heat exchanger.Throttling arrangement 4 is capillary tube or heating power expansion valve or electric expansion valve.Compressor 3 is piston compressor or rotor-type compressor or scroll compressor.Vaporizer 5 is wind-cooled evaporator or water-cooled vaporizer, and wind-cooled evaporator uses fin-tube type heat exchanger, absorbs amount of heat, and water-cooled vaporizer uses double pipe heat exchanger or plate type heat exchanger, absorbs the heat of household tap water.
Control system and protection device include main control chip, overload protection and measure signal port.Wherein, measure signal port connection and include limnimeter, temperature sensor, pressure transducer, be respectively used to measure cistern water level, water tank temperature and compressor temperature, compressor Suck and exhaust pressure.
The present invention solves the problem that the treasured power consumption of little kitchen, existing kitchen is excessive and security reliability is low, use air source heat pump to originate as system thermal, the most both improve system effectiveness, solve again the use safety problem that kitchen is precious, at the same time it can also be the comfort of user is greatly improved.
When kitchen of the present invention treasured system is in idle state, the temperature sensor in water tank can monitor the water temperature inside of water tank in real time, and when tested water temperature is less than set water temperature, heat pump runs and starts.Cold-producing medium, through compressor, enters condenser heat rejection, then enters device for drying and filtering, enters back into choke valve throttling decrease temperature and pressure, then enters evaporator evaporation refrigeration, be finally again introduced into compressor increasing temperature and pressure, complete refrigerant cycle.
Meanwhile, according to the system principle of Fig. 1 and Fig. 2, instant heating type heat pump type water heater of the present invention has two kinds of methods of operation:
1) method of operation one: according to system principle described in Fig. 1, the coil pipe of the condenser of this air source heat pump system is positioned at inside small-sized water tank.When user stops using and miniature water the temperature inside the box is less than setting value, now air source heat pump system starts to start, and heats the water within small-sized water tank, and is finally reached shutdown temperature, and air source heat pump system is out of service, completes to heat the water in small-sized water tank.
2) method of operation two: according to system principle described in Fig. 2, the coil pipe of the condenser of this air source heat pump system is positioned at outside small-sized water tank.When user stops using and in small-sized water tank, coolant-temperature gage is less than setting value, now air source heat pump system starts to start, simultaneously, water mixing valve A and water pump P are run, water in small-sized water tank, via water pump P, enters into water route heat exchanger, and then is heated up, it is then out heat exchanger, is returned in small-sized water tank by water mixing valve A.When the water temperature in small-sized water tank obtains setting value, air source heat pump system is out of service, completes the heating to small-sized water tank internal water.
When the air source heat pump system of the present invention is in use state, according to the system principle of Fig. 1 and Fig. 2, instant heating type heat pump type water heater of the present invention has two kinds of occupation modes:
1) method of operation one: according to system principle described in Fig. 1, when user needs to use hot water, cold water by small-sized water tank bottom through current equalizer, enter inside small-sized water tank, and it is internally formed thermally stratified layer at small-sized water tank, and hot water is flowed out by miniature water box top, for user；
2) method of operation two: according to system principle described in Fig. 2, when user needs to use hot water, cold water through current equalizer, is entered inside small-sized water tank by small-sized water tank bottom, and is internally formed thermally stratified layer at small-sized water tank, and hot water is flowed out by miniature water box top.When small-sized water tank water temperature inside is less than setting value, air source heat pump system starts, and at this moment, water mixing valve A and water pump P are run, and the hot water that user is used is supplied simultaneously to by small-sized water tank and air source heat pump system.
Therefore, according to system principle Fig. 1, shown in 2, whether it is positioned at water tank according to condenser, the system of the present invention can be divided into series and parallel.Tandem heat pump type water heater is only provided the user with hot water by small-sized water tank, and parallel heat pump type water heater can be posed to hot water to user by small-sized water tank and air source heat pump system simultaneously.
Owing to the water heater of the present invention is by heat pump hot water, comparing traditional electrical heating kitchen treasured system, owing to the thermal efficiency of air source heat pump system of the present invention is higher, the overall economic benefit of system the most of the present invention wants height.Primary Calculation result shows: use the Water heater for kitchen of pump type heat can improve about 60% than the whole economic efficiency of traditional electrical heating kitchen treasured system, and can extend kitchen precious go out the hot water time, expand kitchen treasured systematic difference scope.
