Description

A kind of ground-source heat pump system for agricultural greenhouse
Technical field
A kind of ground-source heat pump system for agricultural greenhouse is the utility model is related to, belongs to earth source heat pump application technology neck Domain.
Background technology
In order to keep certain temperature in greenhouse, conventional method is to be heated, greenhouse heating mode Generally electric air-conditioning and hot blast stove system.But take both equipment investments are high, energy consumption is big, effect is poor, be only suitable for it is high-grade, The deficiency applied in the production of high added value greenhouse.Ground source heat pump technology be nowadays in one rapidly rise during, make It is no matter in itself abroad or domestic highly developed for ground source heat pump technology.
Utility model content
The purpose of this utility model is to provide a kind of ground-source heat pump system for agricultural greenhouse for saving the energy.
In order to reach above-mentioned technical purpose, the technical solution of the utility model is:
A kind of ground-source heat pump system for agricultural greenhouse, including ground heat exchanger, the ground heat exchanger connection There is circulation line, evaporator is serially connected with the circulation line, the evaporator is serially connected in compressor, condenser, expansion valve Ground source heat pump hot water unit is formed together, and the condenser is connected with heat storage water tank, and the heat storage water tank is connected with multigroup heat dissipation Circulation line, is provided with fin on the heat dissipation circulation line, the heat dissipation circulation line be located in agricultural greenhouse subsurface or On ground.
In order to control water to circulate, circulating pump is installed on the heat dissipation circulation line.
Temperature sensor is installed, the temperature sensor is used to detect heat dissipation circulation line on the heat dissipation circulation line Interior temperature.The system also includes controller, the signal of the temperature sensor is conveyed to controller, the controller control The work of circulating pump.
Heated as auxiliary, the heat storage water tank is connected with electric heater unit.
Tthe utility model system is simple, easy to control, and less investment can heat greenhouse, carry The high utilization ratio of the energy, reduces the waste of human and material resources and the energy.The temperature requirements scope of most of greenhouses is 30 Within DEG C, either it will be far above this temperature range using fuel oil or electric heating system, obtained temperature, virtually Increase temperature losses.The utility model heat pump system heating temperature belongs to low temperature heating at 45 DEG C~55 DEG C, and the temperature difference is small, loss It is small, avoid the waste of the energy.
Brief description of the drawings
Fig. 1 is the schematic diagram of the utility model.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
A kind of ground-source heat pump system for agricultural greenhouse, including (common ground-source heat pump system is equal for ground heat exchanger 1 Including the funtion part), the ground heat exchanger 1 is connected with circulation line, and water pump 2 and valve body are provided with circulation line, It is serially connected with evaporator 3 on the circulation line, the evaporator 3 and compressor 4, condenser 5, expansion valve 6 are serially connected shape Into ground source heat pump hot water unit, the condenser 5 is connected with heat storage water tank 7, and the heat storage water tank 7 is connected with multigroup heat dissipation circulation Pipeline 10, is provided with fin on the heat dissipation circulation line 10, the heat dissipation circulation line 10 is located at subsurface in agricultural greenhouse Or on ground.
Circulating pump 8 is installed on the heat dissipation circulation line 10, while temperature is installed on the heat dissipation circulation line 10 Sensor, the temperature sensor are used to detect the temperature in heat dissipation circulation line.The system also includes controller, the temperature The signal of degree sensor is conveyed to controller, the work of the controller control loop pump 8.
By heat pump, cooling system loaded on below crop, sunlight is not influenced, can effectively be dehumidified, it is contemplated that than passing Heat pump greenhouse of uniting saves 6% or so energy, and it is more to save energy to modern adiabatic good greenhouse.
When the heat that ground-source heat pump system can obtain is less, heated as auxiliary, the heat storage water tank 7 is connected with electricity Heating unit.
Above-described embodiment does not limit the utility model in any way, every by the way of equivalent substitution or equivalent transformation The technical solution of acquisition is all fallen within the scope of protection of the utility model.
