METHOD FOR HEATING OF GREENHOUSES AND GREENHOUSE WITH SYSTEM FOR HEATING THE SAME

摘要

FIELD: agriculture. ^ SUBSTANCE: method involves drafting air from space under greenhouse shell by means of thermal fan; passing said air through heating device; discharging part of heated air through blowing branch pipe into space under greenhouse shell; feeding other part of heated air via metal pipes first into subsoil layer of greenhouse, then from subsoil layer through pipes directly into space under greenhouse shell. In greenhouse at one of its ends there is thermal fan. Suction pipe of thermal fan is inserted into volume under greenhouse shell and its discharge pipe is connected to metal pipe system positioned under greenhouse soil. System for heating of greenhouse volume with heated air is made in the form of two outer pipes arranged under greenhouse shell. Each of said pipes is extending in horizontal plane along greenhouse sides at height not in the excess of 1 m. Through openings are provided in said pipes through the entire length of side facing greenhouse shell. Each of said pipes is connected with its one end to metal pipe system arranged under soil surface of greenhouse. ^ EFFECT: substantial reduction of heat losses for heating of greenhouse, simplified construction of greenhouse and easy maintenance during heating season. ^ 15 cl, 3 dwg
