Abstract

The invention discloses a solar energy heat collection control system and a heat collection control method thereof, relating to a heat collection control system, belonging to the field of solar energy heat collection control, and solving the problem of existing solar energy optothermal utilization equipment that the utilization rate of energy is low due to energy loss. According to the invention, a first temperature sensor is used for detecting the temperature of air flow at an air outlet of an air pipe and connected with a first temperature transmitter, the first temperature transmitter is connected with a digital input end of a frequency converter and used for controlling the on and off of the frequency converter, and if a set temperature is reached, the first temperature transmitter sends a pulse signal to the frequency converter to start the frequency converter; a second temperature sensor is used for detecting the temperature of an outlet of an air heat collector and connected with a second temperature transmitter, the second temperature transmitter is connected with an analog input end of the frequency converter, the rotation speed of a fan is controlled by the frequency converter, the temperature transmitting range of the second temperature transmitter is from 30 DEG C to 80 DEG C, and air diffusers are installed on an air return port and an air supply port and used for changing the indoor air direction. The solar energy heat collection control system disclosed by the invention is suitable for indoor temperature adjustment.

Description

technical field [0001] The invention relates to a heat collection control system, which belongs to the field of solar heat collection control. Background technique [0002] Solar air collector is a kind of solar heat utilization equipment, which has the characteristics of simple structure, convenient installation and stable performance. It can form the heating and air conditioning source of buildings with other auxiliary cold and heat sources. Flat-plate air collectors are commonly used in practical engineering applications. Its basic structure consists of the following parts: transparent glass cover plate, heat-absorbing plate, external box body and insulation layer, etc. Its working principle is: solar radiation is projected on the heat-absorbing plate through the transparent cover plate, the temperature of the heat-absorbing plate rises, and then the high-temperature heat-absorbing plate exchanges heat with the air passing through the heat collecting box, so that the temp...
