The operation principle of heat pump the ability in source lower for temperature is sent to the higher output electricity of temperature, and its COP is relevant with the temperature of water supply backwater, also relevant with the temperature in source, the temperature in source is lower, then the COP of heat pump is just low, thus makes the whole efficiency of system reduce, and causes the waste of the energy.The source of heat pump is generally gas, such as air, also can be water.
The power of water heater wants high compared with heat pump, but the thermal efficiency ratio water heater of heat pump is high, and operating cost is low.
Current water heater heat pump, although the method for operation being yet water heater and heat pump are assisted mutually, does not consider the efficiency of heat pump, according to the COP Characteristics Control heat pump of heat pump and the work of water heater, causes the inefficiency of system.
Summary of the invention
The present invention discloses a kind of water heater and air source heat pump and to cooperatively interact the integral system of work, makes improvements, thus overcome aforementioned drawback for hot pump characteristics in current water heater heat pump.Its technical scheme is specially:
A kind of water heater heat pump, comprises water heater, heat pump, it is characterized in that, also comprise the first temperature sensor, control module;
The source of heat pump is located in the test side of the first temperature sensor, and its signal output part is sent to the first Temperature numerical input of control module by detecting the Temperature numerical obtained; When the Temperature numerical that the first Temperature numerical input of control module receives is less than the first detection numerical value, make heat pump out of service, make water heater run.Source heat pump heat is less than the first Temperature numerical, and then COP value is too low thus cause waste, reduces entire system efficiency, therefore by detecting the temperature in heat pump source, heat pump can be made out of service when COP value is too low, bear heating tasks separately by water heater.
Further, when the Temperature numerical that the first Temperature numerical input of described control module receives is less than the second detection numerical value, make operation of heat pump, water heater out of service.When source heat pump heat is greater than the second detection numerical value, COP value arrives acceptable scope, and this seasonal heat pump work, makes water heater stop.
Particularly, described first detection numerical value is subzero 5 DEG C or subzero less than 5 DEG C, and the second detection numerical value is more than 0 DEG C or 0 DEG C.
Consider in some cases, the heat that only heat pump work produces is not sufficient to make temperature reach design temperature, therefore make improvements further: the second temperature sensor is set, what be arranged at described water heater heat pump supplies water end (W.E.), the test side of the second temperature sensor is for detecting the leaving water temperature of described water heater heat pump for water end (W.E.), the Temperature numerical that the first Temperature numerical input that the second Temperature numerical input that the Temperature numerical that detection obtains is sent to control module by its signal output part works as control module receives is greater than the 3rd and detects numerical value, and the second Temperature numerical input that the result that design temperature deducts threshold temperature is greater than control module receive Temperature numerical time, make described operation of heat pump, described water heater is made to run.Particularly, described threshold values is more than or equal to 15 DEG C and is less than or equal to 25 DEG C, and described 3rd detection numerical value is more than 0 DEG C or 0 DEG C.
Particularly, described heat pump is air source heat pump, and described water heater is gas-heating water heater.But according to its principle, be applied to water resource heat pump, electric heater etc., be suitable for too.
Accompanying drawing explanation
Fig. 1 is specific embodiments of the invention figure.
Detailed description of the invention
Water heater heat pump in specific embodiment intends the air source heat pump adopted, and water heater adopts gas heater, and the COP value of heat pump is general is only have about 2 at subzero 5 DEG C, 35 DEG C time, then have more than 5.COP data for a certain concrete air source heat pump can set different environment temperatures by laboratory, obtain by experiment.
As shown in Figure 1, specific embodiment is the water heater heat pump that series system connects.Control module, according to the numerical value of first, second temperature sensor feedback, controls the operation of water heater and heat pump.Water circulation aspect, hot water is sent into heating outlet pipe by water after water heater, and enter heating system, after radiator, the hot water of circulation enters heating water return pipe, and enters heat pump, after heat pump, enter water heater.
Heat pump adopts air source heat pump, and the first temperature sensor is arranged at the source of heat pump.Consider the COP curve of relevant air source heat pump, arrange when record the numerical value of subzero 5 DEG C time, control module sends signal makes heat pump quit work, water heater working.If record to obtain the numerical value of 0 DEG C, control module then sends signal and makes heat pump work, and water heater quits work.Thus, heat pump can being avoided to cause inefficiency when crossing low temperature because of self-characteristic, wasting energy.
Although the efficiency of heat pump quantity of heat given up is far above water heater, no matter water heater is electric heater or gas heater, but isolated operation heat pump is still likely not enough to deal with heating needs, therefore, especially for the appearance of this situation, second temperature sensor is set, the test side of the second temperature sensor is arranged at water outlet of water heater mouth, for detecting the leaving water temperature of described water heater, its signal output part is sent to the second Temperature numerical input of described control module by detecting the Temperature numerical obtained; Arrange the 3rd to detect numerical value and second to detect numerical value identical, arranging threshold values is 20 DEG C, therefore the Temperature numerical received when the first Temperature numerical input of described control module is greater than 0 DEG C the 3rd and detects numerical value, and the Temperature numerical that the second Temperature numerical input of described control module receives is when adding that the result of 20 DEG C is less than design temperature, make described operation of heat pump and water heater run simultaneously, until the temperature that the second temperature sensor place records equals design temperature, more again make heat pump work.Setting like this, except raising efficient energy conversion, can also be promoted faster in the temperature of the lower output in season of temperature, be optimized whole efficiency.
If adopt parallel way to connect heat pump and water heater, then the second temperature sensor is connected to the meet of water heater and heat pump water outlet, to detect the leaving water temperature of whole water heater heat pump for water end (W.E.).
Use water resource heat pump and or electric heater replace aforementioned heat pump, water heater, the even heat pump of carbon dioxide source, also can application of aforementioned technical scheme.Only need to consult technical manual, or the COP numerical value that room just can obtain heat pump and relevant environment temperature by experiment just can arrange the first detection numerical value and second according to correlation values and detects numerical value.
