Professional greenhouse insulation can be said to be one of the most common infrastructures for the demonstration construction of agricultural parks. With the advantages of greenhouses, many agricultural plantations such as fruits and vegetables can exert better product value and economic value. At present, greenhouse planting technology is also growing in maturity. Today we will discuss the common heating, cooling and insulation methods of the greenhouse. Let us learn.

Common methods of greenhouse heating include brewing heating, electric heating, water heating, warm air heating, and solar energy storage system heating. At present, in the era of energy conservation and emission reduction, the preferred method is to choose a solar energy storage system to store the thermal energy intercepted by the high-temperature air in the upper part of the greenhouse in the ground to increase the ground temperature. When the temperature at night is lower than the ground temperature, the energy stored in the soil can be discharged into the air. By using a solar storage system, the temperature inside the greenhouse can be increased by 1 ° C.

Second, cooling technology

Ventilation and cooling

The air exchange and cooling operations are very simple, ie open the ventilation outlet or open the ventilation fan for exhaust cooling.

2. Shading and cooling

In summer, the temperature is high and the light is strong, you can use old film or old film with straw curtains, shade nets and other covers to cool down.

3.Indoor spray cooling

One is to spray upward from the side of the greenhouse, and the other is to spray downward from the upper part of the greenhouse. This should be selected according to the type of plant.

4.Fan water curtain cooling system

Professional friends who have good economic conditions can use a fan water curtain cooling system. The cooling process is completed on its core paper pad. The surface of the corrugated fiber has a thin water film. When the outdoor hot and dry air is sucked through by the fan, The water on the water film will absorb the heat of the air and evaporate into steam, so that the treated cold and wet air will enter the room. At this time, the effect of 5≤10 ° C can be achieved immediately in the room.

Third, insulation technology

1. Multi-span greenhouse flat roof and internal insulation

This type of insulation is a lightweight space cotton insulation quilt that is often parallel to the inner sunshade. The insulation quilt has the characteristics of rain and sun protection. The service life is about five years. The opening and closing method is driven by the motor and the rack and pinion. Open and close.

2. Side insulation around multiple greenhouses

It refers to the installation of a layer of lightweight cotton thermal insulation quilt or a layer of thermal insulation curtain on the wall around the greenhouse. The thermal insulation cotton or curtain fabric rolls from top to bottom at night to keep it warm during the day.

3. Add extra small arch insulation around the thin film multi-span greenhouse

This type of insulation is the most common type of membrane multi-span greenhouse style, that is, a small arc-shaped arch is used to support an additional small space around the greenhouse. The bottom of a normal small arch is about 1.5 meters from the wall. The arch can be made by @ It is made of 32≤2.0 round pipes, and the arch interval is 1 meter. At the same time, if a rolling film is installed on the arched surface, the film can be rolled up without affecting the use of side ventilation or fan water curtains.

The above is the introduction of heating, cooling and insulation measures in greenhouses. Among them, there are more greenhouse materials and equipment involved. The most cost-effective method is to use greenhouse insulation quilts, heat insulation in summer, heat resistance in winter, and cold protection in winter. , Applicable life is up to 8-10 years, there are also some dedicated systems, you can buy according to your own financial situation. No matter how good the professional system is, don't ignore some artificial details, and do a good job of controlling the temperature to give full play to the advantages of greenhouse cultivation.
