[1] Heating design of solar greenhouse
Solar greenhouses have very good thermal insulation measures in the Northeast. The reason why there are solar greenhouses in the Northeast. The core of its thermal insulation coefficient lies in its three-sided wall with super thermal insulation, which is thicker than the walls in other regions, and the thermal insulation materials are also thicker. Another thermal insulation material is the front thermal insulation quilt of the solar greenhouse, which is generally made of waterproof wool felt, with double-sided waterproof layers, and high-quality wool felt in the middle. Everyone is also very clear about the insulation of wool felt.

Multi-span greenhouses generally use double-layer glass or double-layer solar panels as the covering material in the northeastern region. The facade of the multi-span greenhouse If the glass multi-span greenhouse uses double-layer vacuum tempered glass, it has a very good thermal insulation effect. The top is basically 8 or 10mm sunshine board, which is also very good for heat preservation. Another type of solar panel multi-span greenhouse, all uses 8 or 10MM solar panels, which are very good for heat preservation. However, the same places of the two greenhouses use internal thermal insulation measures, with thermal insulation layers installed on the top and all around, and their switching methods are electric.
