My home is Mitra air source water heater,The upper temperature limit is 60 degrees,But now it's always warming up,In fact, the water temperature did not go up,But the temperature is rising,Sometimes a sudden jump of tens of degrees.High temperature alarms are also being issued.Tangle, looking for expert..........
The air heat pump hot water unit consists of compressor, evaporator, expansion valve, condenser and so on. The working process of heat pump water heater is as follows: as shown above, a part of the compressor power consumption, low temperature and low pressure refrigerant gas will be compressed into gas with high temperature, high temperature and high pressure gas in the condenser heat heating water, its temperature is reduced, the expansion valve throttling, a gas-liquid mixture at low temperature and low pressure the refrigerant in the evaporator absorbs other media (such as air, water, soil) in the heat, low temperature and low pressure gas into the compressor, and then be absorbed, compressed into gas heating hot water with high temperature and high pressure.
Encountered you this problem, temperature sensing system failure caused by. Usually controlled by a thermistor. It could be caused by its variable value damage. If you do not have the relevant professional knowledge, water heater is a high safety factor of electronic products, I suggest you let the factory after sale deal with this problem more professional, relatively safe! The above hope to help you ~!
The heat transfer medium is a kind of special material, in the actual operation, heat transfer of refrigerant evaporation temperature can reach 20 degrees Celsius, so even if the ambient temperature is 5 DEG relative to it is also the "heat source", can also the normal heat. In addition, the condensing temperature of the working substance can reach 75 DEG C to ensure the output of hot water at 60 degrees centigrade.? absorb the heat in the air for air source heat pumps; absorb the heat in the soil for ground source heat pumps; absorb the heat in the water as a water source heat pump.The United States air heat pump central hot water units (Air-Source Heat Pump Hot Water Unit) is one of the best in the use of new energy development in the world, is a new generation of hot water producing device after boiler, gas water heaters, electric water heaters and solar water heaters after. In today's increasingly tight energy supply, air source heat pump hot water unit with its high efficiency and energy saving, environmental protection, safety and other advantages can be popularized rapidly in the market; the United States has been straight with high temperature thermal cycling series, temperature cycle series, series of comprehensive family hot water unit, full hotels, schools, hospitals, factories, mining a bath, villas, home and other places need hot water. According to the Kano unit inverse circulation principle, with a small amount of electricity as the driving force, with the refrigerant as the carrier, Everfount absorption of low grade heat energy to use air or in the natural environment (-7-43 C), into high grade heat transfer, low temperature and high temperature heat energy to heat energy; the high grade heat released into the water for life hot water (55 degrees, up to 65 DEG C), delivery to the user to meet the heating needs of hot water supply, through the hot water supply pipeline.
