Abstract

The invention discloses a method for controlling cold water supply of a solar water heater and a control system. The control method adopts two modes of cold water supply to supply cold water, the first mode of cold water supply is a water supply control method that an upper limit value of water level is set to be relatively higher in daytime with sufficient light; and the second mode of cold water supply is a water supply control method that an upper limit value of water level is set to be relatively lower at night with weak light. Through the method for controlling cold water supply, the method and the system have the advantages of sufficiently using solar energy, improving utilization rate of solar energy, improving heating speed, saving energy and the like.

Description

[technical field]

[0001] The invention relates to a solar water heater, in particular to a control method and control system for supplementing cooling water of the solar water heater. [Background technique]

[0002] With the improvement of society's awareness of energy saving and environmental protection, more and more solar water heaters are pouring into people's daily life. At present, the cold water replenishment control system of the solar water heater includes a water supply solenoid valve drive module for controlling the switch of the water supply solenoid valve, a water tank water temperature detection module, a water tank water level detection module, and a cold water replenishment control module. When the power is turned on, the cold water replenishment control of the water tank includes the following step:

[0003] 1. Detect the water level in the water tank and judge whether the water level in the water tank is lower than the lower limit of the water level, if ye...
