Description

A kind of phase-transition heat-storage is nursed young plants in hothouses device

Technical field

The invention belongs to Environment Controlled Agricultural Facility technical field, be specifically related to a kind of phase-transition heat-storage and nurse young plants in hothouses device.

Background technology

At present, energy-saving heliogreenhouse is the main Types of northern China heliogreenhouse, can be at the cold bar of-10~20 DEG C Do not heat under part production warm season vegetable, thus whole year production and the supply of vegetable in heliogreenhouse can be realized.But China's sunlight Generally there is indoor air temperature at night in winter in room, ground temperature is on the low side, the phenomenon that Summer Indoor temperature, ground temperature are too high.Winter Solar Greenhouse By utilizing solar energy to realize indoor temperature increasing, under the conditions of fine day, daytime, indoor air temperature can comparatively fast reach plant growth demand, overcast and rainy Snow weather then cannot ensure;The rising of ground temperature relatively temperature relatively lags behind, and therefore indoor ground temperature is consistently lower than temperature, if meeting overcast and rainy snow It is too low that weather is then easily caused in greenhouse ground temperature round the clock, even damages to plants caused by sudden drop in temperature.Though miniclimate can basic guarantee in Winter Solar Greenhouse The growth demand of vegetable, but temperature is less than the optimum temperature of vegetable growth.Summer high temperature then can cause sunlight indoor air temperature and Ground temperature higher than the high threshold temperature of vegetable crop growth promoter, affects crop photosynthesis, simultaneously the breathing of high intensity for a long time Effect weakens organic matter accumulation further, causes vine growth and development slow, and may cause irreversible physiological Disease, thus cause heat evil to occur.Low temperature, damage to plants caused by sudden drop in temperature and heat evil has all had a strong impact on the yield and quality of vegetable.

Root system is that plant absorbs, transports moisture and the major organs of growth desired nutritional material, it is ensured that root system is given birth to normally Life activity and physiological function are significant for ensureing vegetable yields and quality.Root district thermal environment is to affect root system activity One of important factor, has a significantly impact to the accumulation of plant dry matter and allocation model, so have influence on plant growth and Morphological characteristic, and affect the yield of crop.For ensureing the yield and quality of vegetable, it is required to be heliogreenhouse outfit and heats and the summer winter Season cooling system or system.The energy that during industrialized agriculture produces at present, common artificial heating mode is consumed is still with Fossil fuel It is main Deng nonrenewable resources, also there is while causing greenhouse gas emission certain disaster hidden-trouble.It is commonly used for summer The wet curtain fan system cooling-down effect under high humidity environment of cooling is limited, and the shading such as sunshade net cover material can be to a certain degree Affect the photosynthesis of crop.Therefore, develop heliogreenhouse root district thermal environment environment friendly and pollution-free, efficient energy-saving, low cost to adjust Ore-controlling Role and pattern, improve efficiency of energy utilization while ensureing chamber crop quality and yield, reduce energy consumption, have important Realistic meaning.

Potential heat functional thermal fluid (Latent Functionally Thermal Fluid, LFTF) is by phase-change material Microgranule (generally μm magnitude) is mixed into single-phase heat transfer fluid and forms the biphase functional fluid of solid-liquid to reach to strengthen heat convection and storage The purpose of energy.This kind of heterogeneous fluid-mixing has bigger apparent specific heat, has the features such as storage density is high, heat transference efficiency is big, It is a kind of new material integrating accumulation of heat and augmentation of heat transfer function, in fields such as building and heating, air conditioning system and heat exchangers Have a extensive future.Potential heat functional thermal fluid is applied to greenhouse, and daytime stores solar energy by phase-transition heat-storage and prevents greenhouse Interior temperature is too high, and night temperatures releases energy when reducing and heats up for greenhouse, can reduce the temperature fluctuation in greenhouse, make Indoor Temperature Degree keeps relative constancy, thus meets the temperature requirements of plant growth, improves greenhouse thermal environment.

At present, phase-change material application mode in greenhouse mainly have directly to mix, impregnate, form and the building such as filling Material combines and builds phase-change accumulation energy body of wall, or combines exploitation phase-change energy storage device or system etc. with heat collector etc..Phase-transition heat-storage wall Body can accept and the solar radiant energy that absorbs is limited, and heat storage efficiency is relatively low;Existing phase-change energy storage device or system are then many can be accounted for With the working place in heliogreenhouse, or affect the daylighting in greenhouse.It is not yet seen using potential heat functional thermal fluid as Heat storage medium utilizes front roof skeleton efficient heat-collecting to realize the Patents of heliogreenhouse thermal environment regulation and control.
