Abstract

The utility model relates to a greenhouse cold and heat exchange system with a deep-buried ground source heat pump, which mainly comprises a greenhouse, a geothermal well, a geothermal pump, a heat pipe, an electromagnetic control valve, a radiating fin, a temperature sensor and a control host. The geothermal well is digged at one side of the greenhouse; and the geothermal pump is connected with the geothermal well, the heat pipe and the electromagnetic control valve. Hot water in the geothermal well is extracted by the geothermal pump, the hot water passes through the hot pipe and the radiating fin, and cold water reflows to the geothermal well to form a thermal cycle; and according to a signal sent by the temperature sensor, the start and stop of a hot water pump and the opening of the electromagnetic control valve are controlled by the control host, so that crops in the greenhouse is subjected to temperature regulation and control and the temperature is suitable for growth of the crops.

Description

A kind of plastic greenhouse cold-heat exchange system of deep embeded type earth source heat pump
Technical field
The utility model relates to a kind of plastic greenhouse heating system, is specifically related to a kind of plastic greenhouse cold-heat exchange system of deep embeded type earth source heat pump.
Background technology
At China's Middle-north Area, because the particularity of winter climate, the heat that the greenhouse is accumulated daytime is difficult to keep the required temperature environment of plant growth in night, therefore for guaranteeing uninterruptedly carrying out of production process, is necessary to utilize various heating systems that enough heats are provided to the greenhouse.The greenhouse heating system mainly contains following several form, i.e. hot blast heating system, hot-water heating system, solar energy heat distribution system and heat-supply system based upon geothermal energy.The air heating system adopts fire coal or fuel gas hot-blast stove with return air heating in the greenhouse, and the hot gas medium is sent into by airduct, offers regularly many apertures on the airduct wall, makes it to deliver to comparatively equably each position in greenhouse, reaches the greenhouse temperature increasing effect; Hot water heating also is to adopt fire coal or gas fired-boiler heating water, by hot-water line Greenhouse System is heated.The people such as Israel M.Teite compare analysis to these two kinds of heating systems, research is pointed out, although it is substantially the same to keep two kinds of required energy consumptions of heating system of specifying room temperature, but the difference of the two radiating mode is so that when adopting hot-water heating system, the temperature field in whole greenhouse is more even, and those blade face temperature over against hot channel generally are higher than indoor air temperature; Then on the contrary for the air heating system, increased thus the possibility of blade face dewfall, easily make crop generation pathology.Solar energy greenhouse is exactly the energy that utilizes the sun, improve in the plastic tunnel or glass room in indoor temperature satisfy plant growth to the requirement of temperature, but common booth, because its passivity is adopted heat, thus difficult control of temperature caused, sometimes too high because of temperature, also the very important person is releases a part of heat, adapting to the needs of plant growth, and to evening because there not being heat accumulation equipment, causing to be incubated affects animal and plant growth.The geothermal hothouse heating system is in the abundant area of geothermal energy resources, adopts the underground heat water source, and the environmental temperature through pipe heated hotbed's booth is beneficial to plant growth.Can find out the air heating system from above greenhouse temperature increasing system, the hot-water heating system cost is higher, and air in the heating greenhouse, the thermal efficiency is lower, adopt solar energy and traditionally the heat pump temperature-increasing system also be to increase the interior temperature of green house, like this because upwards conduction of hot gas is low to the increase the temperature efficiency of crop, and the solar heating system is difficult to guarantee at night normal temperature.Above traditional greenhouse thermal insulation system cost is high, energy consumption is high, efficient is low, yield poorly, and has affected the development of green house and the realization of target for energy-saving and emission-reduction, also is current greenhouse insulation system problem demanding prompt solution.
Summary of the invention
In order to solve the problem that traditional greenhouse thermal insulation system cost is high, energy consumption is high, efficient is low, yield poorly, deep development and utilize geothermal energy resources system, the utility model that a kind of plastic greenhouse cold-heat exchange system of deep embeded type earth source heat pump is provided.The utility model is the technical scheme that its purpose of realization is taked: a kind of plastic greenhouse cold-heat exchange system of deep embeded type earth source heat pump mainly contains green house, geothermal well, terrestrial heat pump, heat pipe, solenoid electric valve, fin, temperature sensor and main control system.Get geothermal well in green house one side, terrestrial heat pump links to each other with hot well, heat pipe and solenoid electric valve, terrestrial heat pump extracts the hot water of geothermal well, through superheater tube and fin, cold-water reflux consists of a thermal cycle to geothermal well, the signal that sends according to temperature sensor, the aperture of driving booth and solenoid electric valve of main control system control heat-exchanger pump is carried out temperature adjusting to the green house crop, to adapt to plant growth.
Described geothermal well is characterized in that hot well has a bite hot water effluent well and a bite cold-water return well at least, and heat-exchanger pump extracts the hot water of hot water effluent's well, the cold water after heat exchange, and backflow cold water back water well, the degree of depth of hot well is at 18-120 rice.
Described heat pipe and fin is characterized in that heat pipe and fin are metal tube or plastic tube, below ground 40-150 centimeters in heat pipe and the buried green house of heat radiation, and be net distribution.
Described solenoid electric valve is characterized in that solenoid electric valve links to each other with heat pipe with terrestrial heat pump, and feedback signal links to each other with main control system, comes the aperture of by-pass valve control according to the control signal of main control system.
The beneficial effects of the utility model:
Adopted the plastic greenhouse cold-heat exchange system of deep embeded type earth source heat pump, changing traditional green house, to add hot-air be main, for the heating roots of crops soil property be main, greatly improve the availability of geothermal energy resources and Systems balanth, reliability, because the ground source heat pump characteristics, not only solved the problem that heats of winter greenhouse booth, solved simultaneously the cooling problem of Greenhouse in summer booth, increase green house output, saved the energy, improved the life of farmers level.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples;
Fig. 1 is the plastic greenhouse cold-heat exchange system structural representation of a kind of deep embeded type earth source heat pump of the utility model;
Among the figure: 1, green house, 2, geothermal well, 3, terrestrial heat pump, 4, heat pipe, 5, solenoid electric valve, 6, temperature sensor, 7 fin, 8 main control systems.
