The invention provides a capacity-increasing implementing method and device for an air energy water heater. The capacity-increasing implementing method for the air energy water heater comprises the steps that a heat-preservation water tank is detected in real time, specifically, A, according to a delivery test report and actual operation data of the water heater to be subjected to capacity-increasing, the heat transfer process inside the water heater is simplified through a circuit model from the perspective of the heat transfer theory, and the heat transfer process inside the water heater issimplified into the circuit model; B, according to the load situation and the environment temperature, the temperature of a wire of the water heater under the current load condition is calculated, andthe water temperature in the heat-preservation water tank is monitored through a temperature sensor; C, the two times of a current load current are taken as an estimation current, and the temperatures of the two ends of the wire of the water heater under the fault situation are calculated; and D, according to the limitation that the temperature of the heat-preservation water tank is no more than80 DEG C and according to the temperature changing value, changing with the temperature of water, of the wire of the water heater, an improved thermal circuit model of a circuit of the water heater tobe subjected to capacity-increasing is used for judging whether the internal temperature of a transformer of the water heater exceeds the limiting temperature or not under the current load conditionand the current environment condition by calculation.
Description
technical field [0001] The invention relates to the field of water heaters, in particular to a method and device for realizing capacity increase of an air energy water heater. Background technique [0002] Air energy water heaters, also known as "air source heat pump water heaters", "air-conditioning water heaters", "air energy water heaters" and so on. "Air energy water heater" can absorb the low-temperature heat energy in the air, and convert it into high-temperature heat energy after being compressed by the compressor to heat the water temperature. This kind of water heater (air energy water heater) has the characteristics of high efficiency and energy saving. To produce the same amount of hot water, the cost of energy consumed by air energy water heaters is only 1 / 4 of that of electric water heaters, and 1 / 3 of that of gas water heaters. It is more efficient than electric auxiliary solar water heaters. High energy efficiency. The air-energy water heater overcomes the s...
