Around the world, about $10 billion a year worth of crops was lost due to heat waves and drought, researched by The Earth Institute at Columbia University. So there is a trend to move traditional farming into indoor. It’s so called indoor farming. Indoor farming is a method of growing crops or plants, usually on a large scale, entirely indoors. This method of farming often implements growing methods such as hydroponics and utilizes artificial lights to provide plants with the nutrients and light levels required for growth. A wide variety of plants can be grown indoors, but fruits, vegetables, and herbs are the most popular.
INDOOR FARMING AND GREENHOUSE

What is indoor farming?
Why Is HVAC Important to Indoor Farming?
HVAC is part of the indoor farming technology industry that’s set to expand through 2022. As, Markets and Markets notes, “Climate control is crucial in indoor farming, as it creates an environment conducive to plant growth, thereby providing better quality products. To control the climate, hardware components such as climate control systems and lighting systems are essential.”
The HVAC system can be considered to play the most important role in an indoor farm. LED lights are employed to offer the ideal spectrum of light for growth, but they produce a lot of heat.
It is the job of the HVAC equipment to remove some of that heat and to ensure proper airflow to prevent cold spots.
Water cooled package unit
Water Cooled Package unit is a self-contained packaged air conditioners with Water Cooled Condenser. In these packaged air conditions the condenser is cooled by the water. The condenser is of shell and tube type or coaxial type, with refrigerant flowing along the tube side and the cooling water flowing along the shell side. The water has to be supplied continuously in these systems to maintain functioning of the air conditioning system.

All the components of this package AC are assembled at the factory site. The gas charging is also done at the factory thus one does not have to perform the complicated operations of the laying the piping, evacuation, gas charging, and leak testing at the site. The unit can be transported very easily to the site and is installed easily on the plane surface. Since all the components are assembled at the factory, the high quality of the packaged unit is ensured.
