Method and device for realizing capacity increase of air energy water heater

Abstract

The invention discloses a method and device for achieving capacity increasing of an air-source water heater. The method includes the steps that in response to triggered capacity increasing starting operation, the air-source water heater is controlled to start an electric heating mode, and an electric heating circuit is arranged in the air-source water heater and used for electrically heating water in a water tank of the air-source water heater in the electric heating mode; and the water in the water tank is electrically heated to the temperature corresponding to the capacity increasing operation, so that the demand for the total consumption of water at a required target temperature is met after the number of water consumers is increased correspondingly, and the target temperature is a preset outlet water temperature of the air-source water heater. By means of the method and device for achieving capacity increasing of the air-source water heater, the problem that in the prior art, an air-source water heater is limited by the maximum heating temperature, a small quantity of hot water at a target temperature is input, and consequently the demand for a large quantity of hot water cannot be met is solved, the quantity of target-temperature hot water output by the air-source water heater is greatly increased, and user experience is promoted; and moreover, the heating temperature is controlled through intelligent computing, and electric power resources are saved.

Description

technical field [0001] The invention relates to the technical field of electric appliance control, in particular to a method and device for realizing capacity increase of an air energy water heater. Background technique [0002] The working principle of the air energy water heater is to absorb the low-temperature heat in the air, vaporize it through the medium, and then pressurize it through the compressor to increase the temperature, and then transform it through the heat exchanger to heat the water. The high-temperature heat energy after compression is used to heat the water temperature . The air energy water heater has the characteristics of high efficiency and energy saving, and has high energy efficiency. [0003] In the prior art, the maximum heatable temperature of the air source water heater is limited according to the maximum heatable temperature of the compressor. Usually, the maximum heatable temperature of the air source water heater is 55°C, and the target wate...
