A cold Air Blower for Agricultural purpose

摘要

The present invention proposes an agricultural cooling fan having three separate units. According to the present invention, the indoor heat exchange unit (1) is provided with a blower fan, heat exchangers (2, 4) capable of generating cold air by heat exchange with cold water are built in, and the air outlet (8) for discharging cool air in front. ) is provided. In addition, the indoor refrigerant supply unit 100 includes a water tank 110 for storing cold water supplied to the heat exchangers 2 and 4 to generate cold air, and a pump 120 for circulating the cold water. And the outdoor heat exchange unit 200 generates cold water supplied to the water tank 110 by using the built-in refrigeration cycle. The air outlet 8 of the indoor heat exchange unit is provided with a reduced diameter portion 8a in order to increase the flow rate of the discharged cold air. In addition, the heat exchanger built into the indoor heat exchange unit includes a first blowing fan and a second blowing fan arranged coaxially, and a first heat exchanger 2 and a second heat exchanger 4 .
