<p>PURPOSE: A cooling and heating system of a greenhouse is provided to minimize installation of geothermal wells. CONSTITUTION: A cooling and heating system of a greenhouse comprises: an intake well(100) which is formed on a stratum(30) adjacent to a river or lake to use unconfined water as heat source water by collecting; an intake pump(10) which is mounted at the intake well; a foreign material removing unit(120) which removes foreign materials contained in the heat source water supplied from the intake well by a intake pump; a heat exchanger(130) which is connected to the foreign material removing unit; a heat pump(140) which is connected to the heat exchanger for heat exchange of the heat source water and a coolant; a recovery well(150) which collects the heat source water which is heat exchanged with the coolant of the heat pump through the heat exchanger; a heat storage tank(160) which is connected to the greenhouse for collecting heat-exchanged cool and hot water and the coolant of the heat pump to the greenhouse; a first foreign material remover(121); and a second foreign material remover(122).</p> |
