Ring the growth of high value industrial crops, in this regard, measure general in the industry is by the way of booth or other raising temperature
There is provided the temperature of high value economic crops growing, wherein, most of domestic field of planting winter temperatures control and mainly pass through combustion
Coal and boiler grow region room temperature or water temperature to adjust to plant, and not only energy consumption is big but also seriously polluted for this mode, using presence very
Many defects and deficiency, accordingly, it would be desirable to be improved.
Have begun in the industry at present explore the planting process that water source heat pump system is used for high value industrial crops.Its principle is
Beneficial to the heat energy at earth surface shallow-layer water source, earth surface water source (typically within 1000 meters), such as subsoil water, the river of earth's surface, lake
Pool and ocean, absorb the suitable emittance that the sun enters the earth, and the temperature at water source are typically all sufficiently stable.Water source
The operation principle of heat pump techniques is exactly：By inputting a small amount of high-grade energy (as electric energy), realize low-temperature heat energy to high-temperature position
Transfer.The thermal source respectively as winter heat pump heating for the water body and the low-temperature receiver of summer air-conditioning, that is, in summer by the heat in building
" taking " out, is discharged in water body, due to water source temperature low it is possible to efficiently take away heat, with reach summer give build
Build the purpose of thing interior refrigeration；And winter, then it is by water source heat pump units, " extracts " heat energy from water source, deliver to building
Middle heating.This steam generator system adjusting with respect to tradition plantation room temperature, water source heat pump system not only energy-conservation, and zero-emission, no
Pollution, easy to use.
