Method for controlling water supply system

Abstract

The invention discloses a method for controlling a water supply system. The method for controlling the water supply system comprises the steps that the primary hot water output temperature and final hot water output temperature of the water supply system are set; under the water utilization state, the temperature of water in a gas water heater is detected, and whether the temperature of the water in the gas water heater is smaller than the primary hot water output temperature or not is judged; if the temperature of the water in the gas water heater is smaller than the primary hot water output temperature, the gas water heater is controlled to start, or the gas water heater is controlled to stop; the temperature of water in water storage tanks corresponding to water utilization points is detected, and whether the temperature of the water in the water storage tanks is lower than the final hot water output temperature or not is judged; if the temperature of the water in the water storage tanks is lower than the final hot water output temperature, electric heaters corresponding to the water utilization points are controlled to start, or the electric heaters corresponding to the water utilization points are controlled to stop. The method for controlling the water supply system has the advantages of being capable of guaranteeing the constant output water temperature, improving the hot water flowing-out speed, removing cold water in pipelines and outputting the water out of the water utilization points, being large in flow and the like.

Description

technical field [0001] The invention relates to the technical field of water supply equipment, in particular to a water supply system. Background technique [0002] Due to the deficiencies of all energy water heaters, such as the unstable water outlet temperature of gas water heaters, slow water outlet speed and uncontrollable water outlet temperature of electric water heaters, large environmental impact of solar water heaters, and cold water in heat pump water heater pipelines. For this reason, some water supply systems use a combination of multi-energy water heaters. However, the water supply system composed of multiple energy water heaters in the related art can only output a single water point and the flow rate is relatively small. Contents of the invention [0003] The present invention aims to solve one of the above-mentioned technical problems in the related art at least to a certain extent. For this reason, the present invention proposes a control method for a wa...
