This method can control the exhaust pressure and exhaust temperature of the system to a certain extent. When the ambient temperature is high and the water temperature is low, the operating pressure and exhaust temperature of the heat pump water heater will not exceed that of the compressor in high wind operation. safe range, but in this case low wind operation will reduce the energy efficiency of the water heater

The invention relates to a heat pump water heater system and a method for controlling a wind speed thereof. The heat pump water heater system comprises a compressor, a four-way valve, a pressure-bearing water tank, a throttling part, a multi-shift fan and an evaporator, wherein the pressure-bearing water tank, the throttling part and the evaporator are sequentially connected in series, one end is connected with a c end of the four-way valve, the other end is connected with an e end of the four-way valve, an exhaust pipe of the compressor is connected with a d end of the four-way valve, a gas return pipe of the compressor is connected with an s end of the four-way valve, and the multi-shift fan is a radiating part of the evaporator; the heat pump water heater system is characterized by also comprising an exhaust temperature sensor, an environment temperature sensor and a water temperature sensor, the exhaust temperature sensor is arranged on the exhaust pipe of the compressor, the environment temperature sensor is arranged on the evaporator, the water temperature sensor is arranged in the pressure-bearing water tank, and when the heat pump water heater system is working, temperature detected by the environment temperature sensor and the water temperature sensor and the temperature of the evaporator are used for changing a rotational speed of the multi-shift fan. The heat pump water heater system has the advantages that the heat pump water heater system is safe and reliable to use, exhaust pressure and exhaust temperature of the system can be effectively reduced to make the exhaust pressure and the exhaust temperature run within a safe usage range of the compressor, a water heater group can work efficiently all the time, and meanwhile, the water temperature can be appropriately increased.
Description
technical field [0001] The invention is an intelligent wind speed control method adopted by a heat pump water heater system, which can be used for heat pump water heater units of direct heating type, circulation type or static heating type. Background technique [0002] The exhaust pressure and exhaust temperature of the heat pump system have always been an important and difficult point to test the reliability of the heat pump water heater system. When the heat pump water heater operates under the condition of high ambient temperature, the exhaust pressure and exhaust temperature will increase with the increase of water temperature. When the water temperature rises to a certain range, the exhaust pressure and exhaust pressure will The discharge temperature may exceed the safe operating range of the compressor, which may affect the reliability and service life of the heat pump water heater. If it has been running at a low wind speed, even if the system is operated at a high...
