REGENERATIVE GREENHOUSE HEATING SYSTEM

摘要

Disclosed is a heat storage type heating system for a greenhouse capable of maintaining the temperature within a greenhouse in day time and at night in an appropriate temperature range for growing culture crops by selectively storing excessive solar heat within the greenhouse and air heat outside the greenhouse in day time in the winter to use in heating at night. The heat storage type heating system for a greenhouse comprises a heat pump delivering heat from the air at a low temperature to a heat storage tub at a high temperature, or delivering cold heat from the air at a high temperature to the heat storage tub at a low temperature; the heat storage tub connected to the heat pump, storing heat or cold heat, and having a fan coil unit emitting the stored heat to the inside of the greenhouse; an air suction means selectively inhaling the air inside or outside the greenhouse and supplying to the heat pump; a ventilation means selectively ventilating the air generated in the heat pump to the inside or the outside of the greenhouse; a temperature sensor measuring the temperature within the greenhouse; and a control unit controlling the air suction means and the ventilation means by the temperature measured by the temperature sensor. The heat storage type heating system stores heat by using excessive solar heat within the greenhouse and air heat outside the greenhouse in day time, and is able to heat the greenhouse at night, when the temperature is low, by using the stored heat.
