Embodiment Construction

[0014] The greenhouse spray cooling device of the present invention will be further described below in conjunction with the accompanying drawings.

[0015] Such as figure 1 As shown, the closed solar greenhouse cooling device of the present invention is composed of a spray atomization system and a condensation heat dissipation system. The spraying and atomizing system includes a water delivery pipe 1, a condensed water storage tank 2, a high-pressure water pump 3, a condensed water collecting pipe 4, a condensed water collector 5, a spraying pipe, an atomizing nozzle 7, a built-in diaphragm 8 in a greenhouse and a pressure Membrane line9. A water delivery pipe 1 is laid on the ground plane at the front of the greenhouse in an east-west direction, and a condensed water storage tank 2 and a high-pressure water pump 3 are installed underground on one side of the front of the greenhouse. The high-pressure water pump 3 connects the water delivery pipe 1 and the condensed water sto...

Abstract

An enclosed daylight greenhouse cooling apparatus comprises a spraying atomizing system and a condensation heat-radiation system. The spraying atomizing system comprises a water conveying pipe, a condensate water storage tank, a high-pressure water pump, a condensate water collection pipe, condensate water collectors, a spraying pipe, atomizing nozzles, greenhouse built-in separation films and film pressing lines. Condensation heat-radiation system comprises a gravity heat pipe heat exchanger, a cold water tank, a water pump, a hot water storage tank, an axial flow draught fan, an exhaust pipe and a backwind pipe. By the use of the enclosed daylight greenhouse cooling apparatus, problems of large water and heat resource waste due to the employment of ventilating cooling and wet curtain draught fan cooling in the prior facility agriculture, and pest and disease occurrence due to the entrance of germs and pests to the greenhouse through the ventilating port and the draught fan port can be solved; and the enclosed daylight greenhouse cooling apparatus can be simply operated, possesses safety and high efficiency and integrates functions of energy and water conservation, temperature reduction and moisture reduction.

Description

technical field [0001] The invention relates to a cooling device for facility agriculture, in particular to an energy-saving, water-saving and cooling device based on two-phase circulation of water and steam. Background technique [0002] Solar greenhouses have made positive contributions to solving the off-season vegetable supply in winter in northern my country, increasing farmers' income, and improving the living standards of urban and rural residents.
