Description
Technical field
The present invention relates to the air conditioner refrigerating technical field, particularly a kind of iris is cultivated greenhouse heating humidification soil source heat pump system.
Background technology
Current, energy scarcity has become the serious key issue that restricts China's socio-economic development, the energy-conservation important component part as the national energy strategy.In cultivation at some rare flower as the butterfly orchid, the very high requirement to the humiture tool, generally winter, the demand indoor temperature was not less than 15 ℃, and the Summer Indoor temperature is not more than 28 ℃, and annual indoor humidity is not less than 80%, for meeting the demands, on modern market, coal-burning type boiler and the air-heaters of adopting are heated more, and wet curtain humidification, use this system energy consumption large, the land occupation resource is many, cooling in summer difficulty.From reducing energy consumption, reduce CO
2and SO
2deng pollutant, apply the source pump that on market now, electric energy drives and replace coal-burning type boiler.From the angle of the Cooling and Heat Source of system, heat pump can be divided into air source heat pump, water resource heat pump and soil source heat pump etc. again.In the greenhouse heating application, coal-burning type boiler, water resource heat pump and air source heat pump be Shortcomings all.
Coal-burning type boiler: current, China's coal-burning boiler thermal efficiency is low, seriously polluted, and the mechanical automation level is low, exists many deficiencies.Efficiency of fire coal is low, and China's boiler be take coal as main, poor in stove internal combustion condition, and ature of coal is changeable, and boiler is difficult to move according to design point; The separate unit capacity is little, and average every the capacity of life and production labor industry boiler is no more than 3t/h; Seriously polluted, the smoke abatement device imperfection of many boilers, again without desulphurization plant, oke exhaust blackness, dust concentration and SO
2concentration of emission surpasses national environmental standard.In general, when discharging identical heat, the fume amount of coal-burning type boiler discharge is oil burning boiler 11 times, be 500 times of combustion gas, coal fire discharged SO
2for 3 times of fuel oil.
