The invention pertains to a method for regulating the temperature in a greenhouse by insufflation of cooled air into the upper portion of the greenhouse, in case of overheating, and by heating of the lower portion of the greenhouse, in case of a cooling down of same, characterized in that it consists, in the case of overheating, in aspirating the warm air from the upper portion of the greenhouse; to cool this air down by means of a heat pump to a temperature of from about 8/sup 0/ to 15/sup 0/ C. below its initial temperature; to send this cooled down air, eventually with an addition of fresh air, in the upper portion of the greenhouse towards the top of the latter, in order not to perturb the lower area, while for reheating one uses the calories stocked by means of the above mentioned cooling process in at least one low temperature heating circuit provided for with this purpose in mind in the greenhouse. The invention relates also to installations for applying this method.
