Abstract

The utility model discloses a plant frost-proof system, and belongs to the field of agro-meteorological disaster regulation and control. According to an existing frost-proof technique, a lot of resources are consumed, and environment is severely polluted in certain frost-proof methods. Heat in soil is absorbed through a parallel-connection soil heat exchanger with vertical buried pipes, arrives at a heat pump unit through a circulating medium and then is transmitted to a ground heat exchanger on the ground; eventually, heat transferring is carried out between the ground heat exchanger and air, heat is transmitted to the air, and accordingly the temperature of small climate of a plant growth area is increased, and the frost-proof effect is achieved during last frost of the early spring. Meanwhile, the frost-proof effect of a soil source geo-thermal heat pump system is further improved through solar heating.
