A HEATING SYSTEM FOR GREENHOUSE

摘要

PURPOSE: A green house heating system is provided to activate the growth development of crops, and to prevent the damage on the crops by cooling the air temperature inside the green house. CONSTITUTION: A green house heating system includes a temperature detecting sensor(8), a heat collecting unit(10), a ventilator(6-2), a first heat exchanger(12), a connecting pipe(14), a second heat exchanger(16), and a circulation pump(18). The temperature detecting sensor is electrically connected to a controller(4) for detecting the internal air temperature of a greenhouse(2). The ventilator absorbs internal air heat of the greenhouse for storing inside the heat collecting unit.
