Description
Technical field
This utility model belongs to gardening equipment technical field, is specifically related to a kind of air-soil for sunlight greenhouse heating
Earth source heat pump is combined regulation device.
Background technology
Heliogreenhouse is a kind of greenhouse that China is exclusive, with solar energy as main energy sources, utilizes body of wall and underground soil
The accumulation of heat effect of earth, absorbs solar radiation energy daytime, and heat release at night, for the miniclimate ring that the growth offer of warm season vegetable is suitable
Border, makes vegetable more season produce and is possibly realized, ensure the year-round supply of vegetable.Its appearance and develop rapidly and greatly alleviate China
The imbalance between supply and demand of north of china in winter vegetable.Heliogreenhouse general prosthetic firing equipment, by putting aside solar energy daytime to improve indoor
Temperature, is affected bigger by weather.When still there is night or overcast and rainy snow in the use of north of china in winter indoor air temperature, ground temperature is on the low side asks
Topic, causes plant growth slow, even occurs that phenomenon is damaged to plants caused by sudden drop in temperature in freezing, have a strong impact on the quality and yield of vegetable.Investigation finds, north
Fang Xianyou major part greenhouse indoor air temperature in winter, ground temperature are still difficult to reach thermophily gourd, fruit and vegetable production requirement, can only meet one
A little cold-resistant, growth demands of half cold-resistant class vegetable.
For ensureing the yield and quality of chamber crop, it is required to be heliogreenhouse winter and is equipped with warming-up device or system.The most often
With tradition heating mode such as: hot water heating, air stove are heated, steam is heated, electric heater is heated, and its main energy sources used is
Fire coal, fuel oil, combustion gas and electric energy etc., expend substantial amounts of non-renewable Fossil fuel, and causes the discharge of a large amount of greenhouse gases,
Pollute environment.Additionally, fuel price is also constantly rising, causing greenhouse heating mode operating cost to improve constantly, winter heats
Problem has become the bottleneck of heliogreenhouse development.
The thermal source of air source heat pump is air, inexhaustible；Floor space is little, simple installation；Use coolant
Environment friendly and pollution-free；Heating efficiency is high, can realize being obviously improved of energy by consuming small part electric energy, economical and practical, obtains
Widely popularize and use.But there is the problem that when unit runs in the winter time, heating efficiency is undesirable, especially in northern China simultaneously
Winter is colder or outdoor air relatively humid region.Research find, when ambient temperature and relative humidity be in-5 DEG C～5 DEG C and
When more than 65%, the easiest frosting of air source heat pump outdoor heat exchanger so that unit efficiency substantially reduces, need to periodically defrost, consume
Portion of energy.When outdoor temperature is less than-5 DEG C, air source heat pump is difficult to normally work, and needs electricity consumption or other auxiliary thermal sources
Heating air, unit performance coefficient is substantially reduced.Air source heat pump in the use of cold northern area by a fixed limit
System.
Soil source heat pump heat exchanger is embedded in underground, it is not necessary to defrosting, simultaneously because the thermal storage effect of soil, earth's surface is with next
The soil determining depth is higher relative to surface temperature, thus the COP of soil source heat pump device relatively air source heat pump can be higher, tool
There is energy-efficient characteristic.
