Description
Technical field
The present invention is a kind of heat-exchange system, more particularly to a kind of soil thermal storage and heat pipe heat convection system and its heat-exchange method.
Background technology
In all kinds of facilities of agricultural, heliogreenhouse is as China's original creation greenhouse, with its energy-efficient performance advantage,
By the support energetically and popularization of country, it is widely used in agricultural production.But China's traditional agriculture greenhouse generally existing
Daytime is utilized conventional because by solar radiation temperature indoor temperature is too high, nocturnal temperature relatively low the problems such as influenceing crop growth
Energy sources for heating temperature room air, can largely consume energy, and traditional heliogreenhouse can not meet the needs of agriculture energy-saving and emission-reduction development.
Heat storage is used as by epigeosphere soil, 47% solar energy up to earth's surface can be absorbed to, equivalent to 500 times of mankind's power consumption.
Species on greenhouse heating system mainly has：Electrical heating heats, coal burning heating, heat pump heating.It is wherein hot
Pump heating is divided into air source heat pump heating, Heating by Ground Source Heat Pump etc. again.Electric heating system is relatively simple, and initial cost is smaller,
But greenhouse institute calorific requirement is larger, the electricity needed for electric heating system is larger, and required energy cost is higher during utilization, and increase is thrown
It is higher to enter cost fruits and vegetables price, is unfavorable for market sale；The operating cost of coal burning heating system is relatively low, but fire coal can be made
Into the pollution of environment, in the case where common people increasingly focus on air quality, the overall background of energy-saving and emission-reduction, coal-fired heating system is step by step
It is eliminated；Heat pump heat distribution system can realize the target more saved, but mainly come in the season of cold, the thermal source of heat pump
From the air of external environment condition or the soil of underground, the temperature of thermal source is relatively low, and this situation causes the heating technology to heat pump
And performance requirement is higher, the cost of heat pump also uprises therewith.
The content of the invention
The present invention mainly solves the deficiencies in the prior art, there is provided one kind, which proposes, uses air as heat-carrying Jie
Matter, for soil as method of the heat storage medium to greenhouse heating, hot-air is pumped into underground piping through blower fan in daytime greenhouse, passes through ground
The heat exchange of lower pipeline and soil, heat is transmitted to soil storage；Night, there will be the heat in soil to delay by thermal diode
On The Drug Release, so that warm room air keeps constant temperature.When temperature is too low in night greenhouse, system is by hot two poles of automatic start
Pipe, the heat of underground storage take on the ground, to improve temperature in canopy, the patent realize energy " deposit ight day, it is fine to deposit the moon
With ", it has been truly realized a kind of soil thermal storage and heat pipe heat convection system and its heat-exchange method of energy-saving and emission-reduction.
