Description
Technical field
The present invention relates to technical field of air conditioner refrigeration, particularly a kind of iris cultivation greenhouse heating humidification soil source heat pump
System.
Background technology
Currently, energy scarcity has become the key issue of serious restriction China socio-economic development, and energy-conservation is used as country
One important component part of energy strategy.In cultivation of some rare flowers such as iris, have very high to humiture
Requirement, general winter demand indoor temperature be not less than 15 DEG C, Summer Indoor temperature be not more than 28 DEG C, annual indoor humidity is not little
In 80%, it is to meet to require, on modern market to adopt coal-burning type boiler and hot-air blower to heat, wet curtain humidification, with the system energy more
Consumption is big, and land occupation resource is more, and summer cooling is difficult.From energy consumption is reduced, CO is reduced2And SO2From the point of view of pollutant, application is now
On market, the source pump of electrical energy drive replaces coal-burning type boiler.From from the perspective of the Cooling and Heat Source of system, heat pump can be divided into again
Air source heat pump, water resource heat pump and soil source heat pump etc..In greenhouse heating application, coal-burning type boiler, water resource heat pump and air
Source heat pump all Shortcomings.
Coal-burning type boiler：For at present, China's coal-burning boiler thermal efficiency is low, seriously polluted, and automation level is low, deposits
In many deficiencies.Efficiency of fire coal is low, and, based on coal, burning condition is poor in the stove, and ature of coal is changeable, and boiler is difficult for China's boiler
Run according to design point；Individual capacity is little, and life and the average every capacity of production labor industry boiler are less than 3t/h；Pollution is tight
Weight, the smoke abatement device imperfection of many boilers, and without desulphurization plant, blackness of the exhaust, dust concentration and SO2Concentration of emission surpasses
Cross national environmental standard.In general, while identical heat is discharged, the fume amount of coal-burning type boiler discharge is oil burning boiler
11 times, be 500 times of combustion gas, coal fire discharged SO2For 3 times of fuel oil.
Water resource heat pump：Although water source temperature is stable all the year round as soil source temperature, the efficiency of unit is effectively raised
Than, but it is very big to the destruction of groundwater resources, and initial cost is big so that promote extremely difficult.It is big by regional impact.Transport in Practical Project
With in, the utilization cost variance of different water resource is big, can search out suitable water source limit water resource heat pump popularization and
Development；The system of water layer geologic structure.To ensure the stable of underground hydrological condition and saving groundwater resources, from the water that underground is extracted out
Can the recharges of necessary whole, recharge that economic be affected by geological conditions.

The areas such as north will be unable to normal work in the winter time；Vaporizer easy frosting when heating.As air source heat pump winter is made using air
For thermal source, so, with the reduction of outdoor temperature, the moisture in air will be separated out and depend on evaporator surface and form frost
Layer.Evaporator heat transfer thermal resistance increases, and has a strong impact on the overall performance of compressor and heat pump, meanwhile, defrost the surcharge brought
With will also reduce air source heat pump economy；Efficiency is low compared with soil source heat pump.Air themperature is big with seasonal variations, and unit often exists
Run in the case that condensation temperature height and evaporating temperature are low, inefficiency.
Boiler heating principle is simple, and device structure is simple, and operational management is convenient, but the efficiency of coal-burning boiler heating is hotter
Pump is low, and land occupation area is big, and combustion product is big for environment pollution；Water resource heat pump is stable, energy-conserving and environment-protective, without defrosting difficulty etc.
Problem, but affected very big by water layer geological conditions and underground water source condition；Air source heat pump region limits are big, deposit when heating
