And working as the air-conditioning system target for being located at the large space bottom for its temperature of thermal region is more than preset second
When temperature value, then the heating load decline or out of service of the air-conditioning system.
It is especially right in view of the hot wind that Winter heat supply air-conditioning system is sent out is gathered in roof area under the action of heat buoyancy
In large space, the top (i.e. top) that the higher air of temperature is accumulated in large space significantly improves temperature gradient, this hair
It is bright by by heat sink be arranged in large space indoor top, can be used for recycling the heat at the top of winter large space.This hair
It is bright to can use return air preheating device, the heat of recycling is used to heat the return air of central air-conditioning system;Or utilize end
Air supply device is held, the heat of recycling can be used to heat the inorganization in invasive channel and seep wind.
It may be provided with conventional air-conditioning system in large space, when needing to be promoted the temperature in large space, the air-conditioning
System being capable of the heat supply into the large space;Top heat recovery system (mainly includes heat sink, the pre- hot charging of return air in the present invention
Set or/and the components such as end air flow device) can with air-conditioning system (air-conditioning preferably may include that spray is sent in air-treatment unit, side
Mouthful etc.) in winter heating the period run simultaneously, the thermal comfort of public area in enhanced room.It is inhaled in top heat recovery system of the invention
Thermal, return air preheating device, end air flow device operating status preferably by large space bottom temp and head temperature
Control, and linkage control air-conditioning (such as air-treatment unit) heating load.For example, when monitoring large space head temperature
After being higher by setting value (value can be preset), heat sink is opened by temperature controller, utilizes one be attached thereto
Or multiple return air preheating devices preheat return air, while carrying out heat supply to channel using end air flow device and (heating outdoor infiltration
Cold wind);And when the air-conditioning system target positioned at the large space bottom is warm more than preset second for its temperature of thermal region
When angle value, the heating load of original air-conditioning system heat source can be reduced.As it can be seen that the top heat suitable for large space in the present invention is returned
Receipts system handles unit etc. by linkage heat sink, return air preheating device, end air flow device and Air Conditioning, improves
The thermal comfort of public area, and the air conditioning energy consumption of entire large space can be reduced.
Heat sink is preferably disposed in large space rack roofing, for recycling the heat at the top of winter large space;
Return air preheating device can be set in the return air duct of air-conditioning system;End air flow device can be set in outer door,
Wind is seeped for heating the inorganization invaded in outer door;The air-treatment unit of air-conditioning system can send spout to send by side
Wind, for heating entire large space (especially the target of large space bottom is for thermal region).
The large space heat supply in winter period is generally higher by the prevalence of biggish temperature gradient, large space head temperature
6 DEG C of bottom temp or more, 10 DEG C or so are reached as high as, which does not act on occupied zone, eventually by roof
It is lost to outdoor, causes wasting for heating load.The principal element for causing temperature gradient is hot pressing, especially works as construction bottom
There are when larger open, a large amount of outdoor cold airs are entered the room, and hot pressing is caused to be further exacerbated by.Temperature gradient is reduced at present and is changed
The kind comfortable major measure of Base Heat is to improve the air-tightness of external door, including the passive measures such as door socket, air curtain, door curtain are arranged,
And increase the active measures such as air-conditioning heating load;And for the large space of the types such as railway station building, since building uses function
It is required that portal and ticket checking stairs port etc. need whole day to open, entered the station demand with meeting passenger, therefore effective envelope can not be formed
Space is closed, temperature gradient is caused to be significantly larger than general large space, after increasing air-conditioning system heating load, and leads to energy consumption sharply
Increase, and it is unobvious to the improvement of bottom personnel activity region comfort.Therefore the present invention proposes a kind of large space
Top heat recovery system and control method are realized the recycling of top heat using heat pump techniques or hot pipe technique and are carried out in bottom
Release, to realize the carrying and recycling of top heat.
Heat pump techniques may be implemented the thermal energy of low level heat energy moving to high-order heat source, and be used at the top of winter large space
It is then that high-order heat source is moved to low level heat energy, transport efficiency can be higher, it is possible to increase 1.8 times when recuperation of heat.Utilize the technology
When carrying out Heat Migration, after monitoring that large space head temperature is higher by setting value (value can be preset), it is installed on
Heat sink at the top of large space is in operating status, at the same start bottom personnel activity region return air preheating device or/
With end blowing device, the temperature gradient of large space can be effectively improved at this time, the temperature difference of top and bottom can by 6 DEG C with
On be reduced to 0.3 DEG C or so, the heating energy consumption of air-conditioning system can then reduce by 30% or so.
Hot pipe technique can realize the Non-energy-consumption transmission of heat, utilize the working medium density that phase transformation generates between gaseous state and liquid
Difference recycles under the effect of gravity, while phase transition process realizes heat at the top of large space along with biggish heat absorption and heat release
Recycling, when hot end and cold end there are 5 DEG C or more of the temperature difference can Efficient Cycle.When using hot pipe technique, release end of heat and heat absorbing end
Between the temperature difference it is bigger, then heat exchange efficiency is higher.Above, heat absorbing end is under for the heat exchange of heat pipe release end of heat of conventional articulated gravity circulation
Side, when end positions exchange after, then need using elevator pump driving circulation, power be only conventional air conditioning system tens/
One, therefore large space top recuperation of heat is carried out, it can be achieved that nearly zero energy consumption of system increases using hot pipe technique.When recuperation of heat is used
In having with outdoor, when carrying out local heating by the service channel that external door is connected to, the end that release end of heat can be placed in the region is blown
In device, the temperature difference of hot end and cold end is up to 10 DEG C~25 DEG C at this time, therefore hot-pipe system recuperation of heat effect is obvious, by recycling
Heat is directly used in the lower infiltration wind of temperature at heating external door, and the temperature of infiltration wind can be improved, improve the comfort in the region,
The temperature difference of the top and bottom of entire large space simultaneously, can be reduced to 3 DEG C or so by 6 DEG C or more, the heating energy of air-conditioning system
Consumption can then reduce by 10% or so.
To sum up, the top heat recovery system and control method suitable for large space in the present invention, is a kind of band return air
Heat recovery system at the top of the large space of preheating or/and infiltration wind heating, can alleviate the temperature gradient mistake of winter large space
Big problem, while the thermal stratification of large space air conditioning system can be improved, and reduce air conditioning energy consumption, it is particularly possible to it improves
Target positioned at large space bottom is for thermal region (region of waiting as being located at Railway Passenger Stations Waiting Lounge large space bottom)
Thermal comfort.
