Description

Heating and cooling system The present invention relates to a heating and cooling system, and more specifically, to a heating and cooling system in which heating, cooling, and dehumidification are integrated. Heating and cooling systems can be applied to various indoor spaces where people are active, such as residential, commercial, and industrial areas. Recently, they are also being applied to smart farms, and various related studies are being conducted. Smart farms utilize information technology to measure and analyze temperature, humidity, sunlight, carbon dioxide, and soil conditions within crop cultivation facilities, and operate control devices based on the analysis results to maintain optimal conditions. Remote management is also possible via mobile devices such as smartphones. Smart farms can generate high added value, such as improved productivity and quality, across the entire process of agricultural production, distribution, and consumption. As it refers to an agricultural method that employs ICT (Information and Communication Technology), it is a concept applicable to open fields, greenhouses, and plant factories. Generally, smart farms use commercial or residential air conditioners for cooling, electric or oil boilers for heating, and standard cooling dehumidifiers for dehumidification. As such, conventional smart farms face the problem that not only do installation and operating costs increase, but a large amount of installation space is also required, because products suitable for cooling, heating, and dehumidification must be installed individually for each purpose.
