Heating & Cooling Systems
Heating and cooling; a well growing climate
Installations for heating and cooling a greenhouse are essential in the Eastern European country climate. In winter, the greenhouses are heated with warm water, possibly in combination with a hot air heater. New greenhouse projects are more and more often carried out with a boiler in combination with a CHP. A heat power plant (wkk) gives a higher energy efficiency. The CHP produces heat, electricity and CO2. The CO2 released by combustion can, after flue gas cleaning, be used to increase the yield of the crop. By so-called CO2 tubes it is then spread into the greenhouse.
Air humidity is one of the most important growth factors in a greenhouse. The humidity directly and indirectly affects the production and quality of the crop. Modern high pressure mist systems produce a fine and consistent fog which can be used not only in summer but throughout the year to control the climate. For example, with the aid of spraying, you create an optimal climate for the cultivation of cucumbers during the winter.
The consistent mist is so fine that it evaporates immediately and does not reach the crop. With modern fog systems a cooling effect of 5° C to 10° C can be achieved. The windows will open less frequent and they can only open so far, which means that less CO2 is lost. The plants wither less quickly and productivity remains stable.
