Problems solved by technology

However this takes air out of the greenhouse, causing a loss of carbon dioxide in the greenhouse
Fresh air is also supplied from the outside into the greenhouse, leading to the risk of infection with pathogenic bacteria from the outside

Embodiment Construction

[0041] figure 1 A simplified diagram of the device according to the invention is shown. The device comprises a first heat exchanger 7, in particular an enthalpy recuperator. The first heat exchanger 7 is provided with a first series of channels 7a and a second series of channels 7b thermally coupled to the first series of channels. The plant also includes a "standard" heat exchanger 8, ie a heat exchanger equipped only to exchange sensible heat, equipped with a first series of channels 8a and a second series thermally coupled to the first series of channels Channel 8b. The plant further comprises a greenhouse air supply connection 1 for supplying air from the greenhouse to the plant, a greenhouse exhaust connection 4 for discharging air from the plant to the greenhouse, supplying air from outside to the plant The outdoor air supply connection 5, and the outdoor exhaust connection 6 that discharges air from the device to the outside.

[0042] In the heating position, air fr...

Abstract

The invention relates to a greenhouse climate control device comprising a first heat exchanger (7) having a first series of passages (7a) and a second series of passages (7b), Greenhouse air supply (1), outdoor air supply (5) from outside to said second series of channels, greenhouse exhaust (4) from said equipment to the greenhouse, and from said equipment to Outdoor outdoor exhaust (6), wherein said greenhouse exhaust is connected to said first series of passages and said outdoor exhaust is connected to said second series of passages. In this way the air is kept in the greenhouse without being supplied with new air, while the temperature of the air in the greenhouse can be regulated and the separation of the greenhouse air from the outside air is maintained.

Description

Background technique [0001] In the field of greenhouse horticulture, there is an increasing need to control all parameters affecting crop growth and quality. At the same time, there is an urgent need to control these parameters with the lowest possible energy consumption, CO2 production and crop protection product usage. Greenhouse moisture management plays an important role here, on the one hand because the degree of moisture deficit (the difference between absolute humidity and fully saturated humidity in grams of moisture per cubic meter of dry air) determines the nutrient uptake and Health, on the other hand, because evaporation (or condensation) consumes a relatively large amount of energy. [0002] In order to be able to control the room temperature in the greenhouse, in addition to the use of heating devices during the heating season, a greenhouse climate control device is used, which comprises a first heat exchanger with a first series of channels and a second series ...
