Greenhouse Evaporative Cooling System Design

The fan and pad system has been the standard system for evaporative cooling for more than 50 years.

Greenhouse evaporative cooling system design.

The new design of this system eliminates the need for a separate external sump tank and minimizes the amount of piping needed for the system while reducing annoying leaks. Of air per square foot of cellulose pad material are common for greenhouses based on their system design. The two most common evaporative cooling systems used in greenhouses are wet wall systems and portable evaporative coolers. Designed with the grower in mind these cooling pads and systems will use heat in the air to evaporate water from plants and other wetted surfaces that will then cool your structure.

One of the most popular and efficient ways to cool large commercial greenhouses is with a wet wall system. Typical fan and pad greenhouse arrangement. The coolest area of the greenhouse is adjacent to the evaporative cooling pads. 4 presented a detailed treatment of the greenhouse evaporative cooling system.

The most common way of accomplishing evaporative cooling in a greenhouse is with a fan and pad system figure 1. A wet wall system consists of cooling pads encased in large aluminum housing. Physical properties of air to use a psychrometric chart figure 1 to help determine the maximum temperature drop resulting from the operation of an evaporative cooling system it is. They are supplied with water from a pipe above the pads and excess water is collected in a gutter at the bottom.

Figures of 200 350 cu ft. In this system aspen or cellulose pads are mounted in one endwall or sidewall of the greenhouse. The evaporative cooling system. The basis of any evaporative cooling system is the evaporation of water into an airstream.

Roof evaporative cooling is another system where cooling is achieved by spraying water on the roof of the greenhouse. Open top design allows for easy detection and cleaning of. The water evaporates taking heat from roof and cools the roof surface. Evaporative cooling for greenhouses relates to the evaporation of water either by re circulating evaporative pad cooling systems or by high pressure fog systems or a combination of both.

With multiple designs and sizes for both greenhouse swamp coolers and evaporative cooling walls available growers can find the right equipment for their operation no matter the requirements. Here roof cooling is independent of the internal humidity level of the greenhouse and the inside air is sensibly cooled because of a colder roof. Growers can also work with a greenhouse specialist to design a custom evaporative cooling system strong enough to manage temperatures on any scale.
