Heat pump greenhouse

Abstract

The invention discloses a heat pump greenhouse, comprising an evaporator, wherein an inlet is communicated with a hot water source by a pipeline, an outlet is communicated with a wastewater outlet, and the hot water enters the evaporator through the inlet and is discharged from the outlet after emitting the heat; and a heat pump compressor, wherein a inhalation end is connected with the evaporator and an exhaust end is connected with a heat exchanger, and the heat pump compressor, from the evaporator, absorbs the heat emitted by the hot water in the evaporator, and transmits the heat to the heat exchanger by a working medium. The heat exchanger is connected with the greenhouse by a water circulation system by which the heat exchange is realized between the heat exchanger and the greenhouse. The hot water source is a geothermal well or a sewer line. The heat pump greenhouse, using heat sources such as underground water in planting area, industrial or domestic sewage, exhaust gas, etc., extracts the heat with the heat pump technology for heating so that an energy-saving, environmental and low-carbon production mode is realized, a cheap and sufficient heat supply is provided to the greenhouse of agricultural productions, and the production operating cost of the greenhouse is reduced.

Description

technical field [0001] The invention relates to a greenhouse facility, in particular to a heat pump greenhouse. Background technique [0002] A greenhouse is a facility that can transmit light and keep warm, and is used to cultivate plants. In seasons that are not suitable for plant growth, it can provide a growth period and increase production. It is mostly used for planting or raising seedlings of temperature-loving vegetables, flowers, forest trees and other plants in low temperature seasons. . There are many types of greenhouses, which can be divided into many types according to different roof truss materials, lighting materials, shapes and heating conditions, such as glass greenhouses, plastic greenhouses; single-span greenhouses, multi-span greenhouses; single-roof greenhouses, double-roof greenhouses; Heated greenhouse, unheated greenhouse, etc. The greenhouse structure should be sealed and insulated, but it should be convenient for ventilation and cooling. Modern ...

AI Technical Summary

Problems solved by technology

Greenhouse planted facility agriculture should be the growth point of agricultural development. However, the climate in northern Xinjiang is relatively cold. Most of the developed greenhouse planting greenhouses only played the role of delaying autumn and late spring, but failed to play their due role in winter. The main reason is the high energy consumption of coal-burning in winter and the high production cost. Therefore, the high energy consumption of greenhouse planting has become a bottleneck problem restricting the development of facility agriculture.
