Description
Technical field
The utility model relates to employing drainage tested static heated type or circulation heated type Teat pump boiler performance, is a kind of air source hot pump water heater drainage performance detecting system specifically.Described tested air source hot pump water heater comprises: the static heated type Teat pump boiler of air source, air source circulation heated type Teat pump boiler also comprise heated type Teat pump boiler of air source simultaneously.
Background technology
Along with the expansion of air-conditioning technical in application, a kind of pot-type boiler of heat pump techniques that adopts has occurred, and with its rapid occuping market of efficient and energy-conservation characteristics.For standard market, country has implemented GB/T 23137-2009 " family expenses and similar applications Teat pump boiler " issue in 2009.
Standard GB/T 23137-2009 " family expenses and similar applications Teat pump boiler " provides heated type one time, Teat pump boiler detection method and requirement that circulation heated type and static heated type are three types, the wherein temperature difference discharge method test of a heated type Teat pump boiler employing, detection computations method with the hot and cold water unit except the working temperature difference is the same, and circulation heated type and static heated type Teat pump boiler all are furnished with reserve tank, with the detection method of a heated type be diverse, have the heating coil pipe in the reserve tank of especially static heated type, impossible employing standard water tank in testing process (the standard water tank: fix by the volume that adopts predetermined material and insulation measure to make, can external mixing arrangement, and be furnished with the thermocouple temperature measurement network at tank inner wall, in order to the distribution of water temperature in the test water tank, thereby can calculate the special water tank of the medial temperature of water in the water tank, the not explanation of standard water tank in the national standard.), establishing criteria GB/T 23137-2009 adopts the test of water tank mixing method to circulation heated type and static heated type, and method of testing is:
Water tank filled with 15 ℃ water, start operating heat pump water heater unit and begin heating, reach 55 ℃ until unit water tank water temperature, out of service, the employing flow is that the discharge of per minute 1/2 water tank volume is carried out the water tank mixing, mixes water pump and should be the non-metal case body structure, and incorporation time is 3min, test the temperature of water tank then, the heat pump heating capacity is according to formula:
Q＝1.163×U×(T
2-T
1)
In the formula: U=V/H heats outlet capacity,
V: be heated the volume of water, unit is for rising (L);
H: the time of unit (Teat pump boiler unit) operation, unit is hour (h);
But there are several defectives in mixing method in detection:
1, the standard-required water tank mixes, and with flow the mixings 3min of per minute 1/2 water tank volume at least, water pump should adopt the non-metal case body structure, and purpose is to be rapid mixing, reduces to leak heat, but does not consider that to mix the discharge that requires too big, is difficult to realization.
With water tank volume 300L is example, and circular flow need be greater than 9T/h, and the water velocity maximum will reach more than the 65m/s, be difficult to select suitable water pump, even if suitable water pump is arranged, power is also inevitable very big, and the heat of water pump must have influence on the temperature of water in the operational process.Detection method (GB/T18708-2002 " the family expenses solar hot water system thermal behavior test method " 7.6.1: start mixing pump that in the standard GB/T of the solar water heater that cisten mechanism is arranged equally 18708-2002, has water tank to mix equally, flow with 400L/min～600L/min, the water of thermal storage water tank's bottom is extracted into the top to circulate and mixes water among the thermal storage water tank, make the even water temperatureization among the thermal storage water tank, at least in the 5min thermal storage water tank's temperature in T1 change be not more than+0.2 ℃, 3 temperature in the record water tank, the water temperature the when mean value of T1 and 3 temperature is the thermal-arrest off-test in the thermal storage water tank.Incorporation time is generally about 30min.), traffic requirement is 400L/h～600L/h only, adopting this flow is to realize easily in practice.
2, adopt the mixing water pump that the water of water tank is mixed, in mixed process, certainly will cause the loss of heat, and the amount of loss is difficult to calculate;
3, the standard-required water tank temperature is the medial temperature of water tank, but be difficult to determine the medial temperature of water tank in the actual test, because unit water in the water tank in heating process can produce thermal stratification, the temperature height in the above, below low, can only estimate water tank temperature by water tank measuring point temperature, can not in unit operation, carry out the mixing of water tank;
4, standard is not considered the heat absorption of water tank self, and in fact water tank is to have the heat absorption phenomenon, and heat absorption numerical value along with the water tank size with internal material difference and different;
5, the water tank of static heating type water heater is because the existence of system's coil pipe, and the water in the water tank is put unclean, and there is mattress in water tank upper, in each test in the water tank amount of water what all be what to exist than large deviation;
Mixed effect, the leakage heat in the mixed process, the caloric receptivity of water tank self, the water yield deviation of water temperature all must cause test deviation and the repdocutbility of heating capacity, COP poor in the water tank.
