Abstract

The invention relates to a mode of a temperature difference forced circulation solar water heating system for automatic identification of weather conditions. The mode comprises the following steps that (1) two timers are arranged on each heat collection circulating pump; and twenty-four hours in a day are divided into the night, the morning or evening, the daytime clear day or daytime cloudy day,the morning or evening and the night; (2) a power source is connected, and an automatic control facility of the temperature difference forced circulation solar water heating system can be located in aparameter setting state; and meanwhile, a control module 0 of the automatic control facility calls a control program so that the heat collection circulating pumps can be located in a working state; (3) control parameters are set and stored in a control module I of the automatic control facility; (4) the current control state of the system is determined; (5) a control module V in the automatic control facility is automatically located in a running state; (6) a control module III in the automatic control facility is automatically located in a running state; and (7) a control module IV in the automatic control facility is automatically located in a running state. The mode can achieve stable and effective automatic identification of the real-time weather conditions.

Description

technical field

[0001] The invention relates to solar energy application and automatic control technology, in particular to a mode of automatic recognition of weather conditions by a temperature difference forced circulation solar water heating system. Background technique

[0002] When the solar-thermal energy conversion technology is used to provide the building with the domestic hot water heat load required throughout the year and the heating heat load required in the heating season, it constitutes a solar heating and heating system; When the domestic hot water heating load required in the year and the cooling load required in summer constitute a solar heating and cooling system. Whether the solar-thermal energy conversion technology is used for cooling or heating, its ideal working mode is to maximize the use of solar energy under the premise of meeting the cooling and heating loads required by the building and the moderate requirements of the human body, so as to achiev...
