Anti-freeze flat plate solar collector and design method thereof

InactiveCN104266383ALarge heat capacitySlow down startupSolar heat devicesSolar thermal energy generationTemperature controlExtreme weather

The invention discloses an anti-freeze flat plate solar collector and a design method thereof. The design method is characterized by determining the thickness of phase change energy storage material through the local meteorological data. According to the anti-freeze flat plate solar collector, phase change energy storage plates are regularly and tightly arrayed between a heat absorbing plate and an insulated layer; a baffle plate is arranged in each phase change energy storage plate along the length direction; a temperature sensor and a temperature controller are arranged at the upper and lower surfaces of the phase change energy storage plate at the solar collector outlet. When the temperature of the heat absorbing plate is lowered to the phase change temperature of the phase change energy storage material, energy storage materials in the phase change energy storage plates generate phase change and release latent heat to prevent the temperature reduction so as to achieve freeze resistance. When meeting extreme weather, a temperature controller starting pump can be used for resisting freeze forcibly and circularly. The anti-freeze device is simple in structure, safe and reliable, the heat loss is low, and the damage to the flat plate solar collector due to icing can be avoided effectively.
