Greenhouse Air Conditioning
Why are we Greenhouse air conditioning? Because greenhouses can absorb up to 300 BTU/HR of energy per square foot. And because plants can only absorb so much energy, they can suffer from excessive heat during warm days. This is why greenhouse air conditioning is essential to keep plants healthy. To solve this problem, new green air conditioning technologies are needed. They will need to hit the market by 2022 and capture nearly 100 percent of sales by 2040.
The simplest form of greenhouse air conditioner is evaporative cooling, where a fan on the opposite wall pulls warm air through pads. The water evaporates, lowering the greenhouse’s temperature. Moreover, these systems increase humidity, which is important for plants. Ideally, the humidity level should be between 50 and 70 percent. Evaporative coolers work in the same way as misters. But they use water to a much greater degree. They are capable of cooling down a greenhouse ten or twenty degrees.
Another common method of greenhouse air conditioning is through forced ventilation. Exhaust fans are mounted on the end walls and pull air in during winter. Air comes in through a motorized shutter in the winter and exhaust fans pull air out of the greenhouse. Using forced ventilation, it is possible to control the temperature and humidity of a greenhouse without affecting its quality. A well-designed system will provide the temperature and humidity levels your plants need to be healthy.
Why Are We Greenhouse Air Conditioning?
The use of air conditioning is a leading cause of climate change. Emissions from AC units are predicted to rise because of the economic growth that continues to drive the need to control humidity and temperature. While the energy used to run air conditioning units has been extensively researched, the impact of removing air moisture has received little scientific attention. However, a new study suggests that controlling humidity accounts for nearly half of the energy-related emissions in the world.
Another method is to use a forced-air heating system. Many plastic greenhouses don’t have adequate openings so humidity will build up and cause leaf diseases. In addition, a forced-air heating system will mix the air in the greenhouse so that temperature variation will not occur. Besides, fans on the walls will circulate warm air and mix it with cooler air near the surface. They can also be operated continuously when the greenhouse is cold.
The goal of greenhouses is to protect plants from external factors, removing any dependence on the environment. Greenhouse air conditioning systems are available in two major types: heating and cooling systems, as well as humidification systems. Depending on what type of greenhouse you have, you’ll need to decide how much cooling is needed. For most people, this is a relatively small price to pay, especially when you consider how much your greenhouse is worth.
