Abstract

The invention relates to a greenhouse heat supplying device comprising a phase-change material plywood wall, a generator, a solution heat exchanger, a condenser and a lithium bromide solution recovery device. The condenser is placed between interlayers of the phase-change material plywood wall, the solution heat exchanger is connected with the condenser through the generator, the condenser is connected with the lithium bromide solution recovery device, and the lithium bromide solution recovery device is connected with the solution heat exchanger, so that circulation is formed. The generator is connected with a solar heater. The solar heater supplies a heat source. A coil pipe in the solar heater is connected with a cold water supplying pipe in the lithium bromide solution recovery device. According to the greenhouse heat supplying device, heat supplying for a greenhouse at night in the colder northern area is achieved effectively, so that the problem of the insufficient heat supplying amount at night of the greenhouse in the northern area in winter is solved; and the greenhouse heat supplying device is low in operation cost, and good in benefit.

Description

technical field

[0001] The invention relates to an energy-saving and environment-friendly heating device, in particular to a heating device for a greenhouse. Background technique

[0002] Lithium bromide absorption system has a wide range of applications, especially in absorption refrigeration and heating industries. It mainly uses the low boiling point and water-soluble properties of lithium bromide for refrigeration or heating.

[0003] At present, the greenhouses put into use in our country have been favored by many farmers. In particular, the three-up and one-slope greenhouse evolved on the basis of the soil greenhouse in northern my country, which has distinct Chinese characteristics. This kind of greenhouse has the advantages of low operating cost, simple structure and convenient management, and has been well developed in facility agriculture. The wall of the greenhouse is the main component of the greenhouse enclosure structure, and its thermal performance has a sig...
