Embodiment Construction

[0021] The specific implementation of the present invention will be described in detail below in conjunction with the drawings and preferred embodiments.

[0022] A method for calculating the heat of solar water heater, including the following steps:

[0023] Step 1: Set the water temperature of the water tank to T 0 Initialization, T 0 =0;

[0024] Step 2: Collect the water tank water temperature T at time i through the temperature sensor i And record, collect and read the water tank temperature T at time i-1 i-1 ;

[0025] The heating rate of conventional solar water heaters under daylight conditions is a few minutes to ten minutes and rises by 1℃, while the cooling rate caused by the user's water consumption is very fast, and the fastest can drop by about 1 to 5℃ per minute. The sampling interval of the controller is very small, generally in the order of seconds or milliseconds. For the temperature collection of the solar water heater, the temperature change of the water tank can b...

Abstract

The invention relates to the technical field of solar water heaters, in particular to a solar water heater controller. The solar water heater controller comprises an MCU, a temperature collecting module, an output module, a display module, an input module and an energy metering chip. The MCU is connected with the temperature collecting module, the energy metering chip, the display module, the input module and the output module. The energy metering chip is connected with a voltage collecting sensor and a current collecting sensor. The temperature collecting module is connected with a water tank water temperature sensor and a pipeline water temperature sensor. The water tank water temperature sensor is installed on a water tank, and the pipeline water temperature sensor is installed on a main circulation water supplying pipe. The output module is connected with an electric heating pipe, a circulation electric valve and a water pump. People can know the advantages of energy saving and money saving of the solar water heater more visually, and the enthusiasm of people for using the solar water heater is improved.

Description

Technical field [0001] The invention relates to the technical field of solar water heaters, in particular to a method for calculating the heat of a solar water heater and a solar water heater controller. Background technique [0002] The current solar hot water controllers, whether they are integrated solar water heaters, balcony wall-mounted split solar water heaters, or centralized heat collection and household heat storage, all have only temperature display, antifreeze, and electric heating functions. The more advanced ones have Turn on the electric heating function in time intervals. These tasks only satisfy the daily use, and do not highlight the advantages of solar water heaters using free renewable energy, and people cannot intuitively understand the contribution rate of solar energy. Summary of the invention [0003] The purpose of the present invention is to overcome the above technical shortcomings, and provide a solar water heater heat calculation method and solar wate...
