Greenhouse And Nursery

[1] Thermal storage system

Heat storage principle:

lPE solar water thermal insulation wall is made of special material PE;

lThe wall material is a thermoplastic resin obtained by polymerization of ethylene, which is odorless, non-toxic, has excellent low temperature resistance (minimum operating temperature can reach -100~-70°C), good chemical stability, and can withstand many Acid-base erosion;

lThe appearance of the heat storage wall is black, with weak reflectivity, which can fully absorb sunlight and store heat efficiently;

lWater (4.2*10^3J/(kg*℃)), a natural and cost-effective large specific heat capacity liquid, is poured into the solar water thermal insulation wall, which absorbs a large amount of sunlight energy during the day and releases a large amount of solar energy into the greenhouse through heat transfer at night. Thermal energy to heat up the greenhouse.

【2】Insulation system

Insulation principle:

lThe three-dimensional hollow moisture-proof and light-transmitting thermal insulation quilt is made of double-layer transparent PO film and filled with three-dimensional hollow chemical fiber cotton (polyester staple fiber) in the middle;

lThree-dimensional hollow chemical fiber cotton is spiral, which is an advanced material for thermal insulation materials;

lIt has the characteristics of strong light transmission, good air permeability, good warmth retention, light texture, strong resilience, not easy to deform, anti-aging, and non-mildew;

lThe three-dimensional hollow moisture-proof and light-transmitting thermal insulation quilt has excellent fluffy performance, and the voids in the cavity can reduce convection, heat transfer, and thermal radiation, and play a good role in thermal insulation.

【3】Ventilation system

Ventilation principle:

lTop skylight ventilation device - The air pressure in the greenhouse is high in summer, and the hot air gathers upward. A skylight is set on the top of the greenhouse, which has excellent ventilation, dehumidification and temperature adjustment effects, and can quickly adjust the temperature and humidity in the greenhouse.

lSide ventilation - Open the side shed film of the greenhouse in summer, which can achieve large area, rapid rate cooling and dehumidification effect.

lFan ventilation device - set the fan device on both sides of the greenhouse. In winter, the fan can be used to remove moisture from the greenhouse, and at the same time, the difference in air pressure inside and outside the greenhouse can be used to deliver fresh air to the greenhouse. Because the device is set at a higher place, the cold air spreads evenly into the greenhouse through the upper buffer cavity, and the cold air will not be directly blown to the plants, so as to avoid the plants from being stressed by the cold air and let the plants grow healthily.

【4】Intelligent IoT

The principle of intelligent IoT:

lIntelligent IoT control box - can monitor the temperature, humidity and other planting indicators in the greenhouse in real time, and realize intelligent management such as automatic adjustment of temperature and humidity and automatic lifting and lowering of quilts through manual setting of temperature and humidity.

lMobile phone intelligent IoT APP - can monitor the greenhouse from all angles and all-weather, and realize remote intelligent control of greenhouse management according to the needs.
