Greenhouse cooling and heating system
Choosing a suitable greenhouse cooling and heating system to regulate and maintain temperature, humidity and air conditioning is vital and permanent in most greenhouses. In this text, we examine the types of greenhouse cooling and heating systems such as greenhouse heater unit, greenhouse air conditioner, Econopac, Zent and air washer in terms of fuel consumption, benefits and features so that it can be a good guide for choosing the right greenhouse cooling system. Or be a greenhouse heating system. Greenhouses must provide a controlled environment with adequate light, temperature and humidity suitable for crop growth. Their temperature depends on the type of growing crop. Often, products require a temperature of 21 to 27 degrees Celsius during the day. In some cases, the relative humidity of the air must also be controlled. Some plants also need low temperatures (for example, 10 degrees Celsius) to grow

Greenhouses' cooling system
 Air rotation fans
One of the most important tools for products to remain fresh is using a greenhouse fan. Air rotation fans with low consumption and sound, and high aeration, have a protective lace and cause even distribution of the temperature and moisture.

Greenhouse fan tasks
•Control the greenhouse temperature
•control the air circulating by greenhouse fan
•Avoid blasting the products
•Increase in pollination
•Setting the moisture in the greenhouse depends on plant type
•Provide the required CO2 for plants' photosynthesis
