A double layered greenhouse(vinyl house) of an interior vinyl sheet and exterior vinyl sheet with a heating device comprising a temperature sensor, heat exchange part, circulating a fan device and a control unit is provided. The greenhouse can obtain heating effect without fire danger and reduce maintenance cost. The double layered greenhouse comprises an exterior support member(10), exterior vinyl sheet(20), interior support member(30) and interior vinyl sheet(40) for forming a heat-retaining space(S1) and heating space(S2) and has a heating device consisting of: a first temperature sensor(51) for measuring the temperature of the heat-retaining space; a second temperature sensor(52) for measuring the temperature of the heating space; a third temperature sensor(53) for measuring the temperature of the object to be heated; a first heat exchange part(60) for heating the object to be heated; a circulating fan device(70) for forcibly circulating air in the heating space to an air inflow line(L1), first heat exchange part and air return line(L2); and a control unit(80) for controlling the operation of the circulating fan device. |
