Purpose: In this study, in order to promote the distribution of smart farms that can solve farm problems, the alternative system and economic evaluation were conducted to apply cooling technology for each user's situation. Method: Based on the prior analysis of the cooling technology in greenhouses and the technologies used in farms, several technologies were combined to form cooling packages. The basic configuration package is Cooling Package 1, and the system that can handle cooling load through heat pumps and heat accumulators is established. The basic configuration is Air Heat, and the air conditioner that can be recycled through return duct is planned and analyzed as Cooling Package 3. Cooling Package 4 is a system using direct expansion air conditioner, and Cooling Package 5 is a system using geothermal sources, which analyzes initial investment and maintenance costs for a total of five systems and performs LCC evaluation. Result: When energy simulation was conducted using the cooling technologies analyzed based on previous studies, the unit cooling load per area was analyzed to be about 435.2W/㎡. Based on the calculation details of 9 greenhouses, the price per unit area is surveyed and the package LCC evaluation analysis that combines cooling technology based on capacity suitable for greenhouse cooling loads, it is expected that farmers will be able to make appropriate choices.
