<p>The present invention relates to a multifunctional cooling and heating device to supply hot air, hot water, cold air, and cold water, comprising: a cold water supply pipe to which water is supplied from the outside; a burner to provide firepower to supply hot water and hot air; a first hot water heat exchange part to heat hot water using the burner′s firepower; a hot and cold air heat exchange part which supplies hot air using the firepower of the burner or cold air using cold water supplied from the cold water supply pipe; and a case in which the first hot water heat exchange part and the cold and hot air heat exchange part are installed. Therefore, the multifunctional cooling and heating device to supply hot air, hot water, cold air, and cold water maintains an optimum condition inside a greenhouse and an optimum temperature of the ground for cultivation by supplying hot air and water during the winter and cold air and water during the summer; thereby increasing farming income. Additionally, the multifunctional cooling and heating device to supply hot air, hot water, cold air, and cold water is economically efficient and environmentally friendly by significantly reducing fuel consumption and heating costs.</p> |
