Heat Pump Water Heater Diagnosis And Prescription Of Three Radical Three Symptoms - Heat Pumps,

Channel Recommended: HVAC 2008 inventory of the first half of the most popular products

Heat pump water heater Symptom 1: Set the temperature or the temperature rising slowly fail. However, some engineering unit to run longer than the design time many still can not reach the water temperature, can barely even hot water can not be used directly, the measured temperature is around 40 or lower, the system vomit? Pump Vomit constantly fine? Exposed acetylene suffering?? Off?

Diagnosis of a heat pump water heater: Air Source Heat Pump Hot water unit outlet temperature is set at between 50 ~ 60 , and occasionally higher than 60 at 65 , the following also belong to the extent permitted only condition may affect the unit running life. Rise in water temperature must be the heat from the outside world. Tank water temperature do not increase when the two sides will be, on the one hand is large or equal to the loss of heat into the heat, when the two are equal, the water temperature constant. Heat loss also includes two possibilities, one is not enough insulation temperature difference between the quality and nature too serious heat dissipation, especially water tank insulation untight seal manhole cover bad or not doing some insulation, thermal insulation and external receiver box discontinuous insulation will increase heat loss; other heat loss up the water flow into the cold water at the same time. This heat loss is found in water tank design, some customers asked for the 24 hours of water in nature, such as traffic larger hotels, such as barber city water customers, cold water rushed into the water tank, hot water ready to use. Air source heat pump water heaters are not problems, if the weather suddenly cold, the heat from the air unit from doubly reduced, while increasing customer usage of hot water, when the heat retained in the tank on the lack of difficult for the temperature rise on the show, and even cold-water phenomenon.

Compressor In various operating conditions have a more stable working ability. Random testing with a single batch unit of work situations, to mark certification, manufacture date, number and so on. Product transport, there is not handling the situation according to label, so some leakage of refrigerant lost and fail to get results, we also lead to reach the design temperature of the water temperature.

Prescription of a heat pump water heater: According to our diagnostic analysis should first check to see whether the excessive consumption of water per day, every 1kg increase in water absorption 1Kcal 1 heat equivalent to 1.163 10-3KWh, both 1000Kg of water by 1 degree, be absorbed 1.163KWh heat. The formula is: water (tons) temperature 1.163 / unit power Kw COP value design time (hours), for example: cold water temperature is 15 , outlet water temperature set to 55 , unit power 2.2KW, in low winter temperature, COP = 2 (manufacturer published data), engineering design for the 1 ton of water, the crew working time 11 hours "Design maximum working time of 20 hours, the same water as the working conditions 2 tons, the unit working time of 22 hours
