Refrigeration storage loss and air circulation experiment

Experimental effect: The cold air permeation heat consumption refers to the heat consumed by the indoor and outdoor air, and the heat consumed by the hole entering the room, which is the so-called non-human tissue (unorganized) heat consumption, which causes the outdoor cold air to pass through the gap or periphery of the door and window. Other small holes in the structure. The reason for the pressure difference between indoor and outdoor air is generally divided into wind pressure action and hot pressure action. Multi-storey buildings only need to consider the wind pressure effect. The cold air permeation through the gap between the door and window and the room height, the door and window structure and North Korea, hot pressing, outdoor wind speed and wind direction are uniform.

The space of the chiller is similar to the indoor and outdoor environment. The problems to be dealt with and the spatial changes are basically the same. The preservation of the cooling capacity is affected by the environmental changes. In order to better improve the efficiency and save the cooling capacity, it is necessary to ensure the air flow but reduce the loss. The method ensures both the quality of the water and the effect of the cooling capacity.

Theoretical calculation method: There are three methods for cold air infiltration heat consumption: gap method, gas exchange number method, and percentage addition method.

1 gap method

The gap method is used to calculate the air permeability of the room, and the balance between the total infiltrated air volume and the air volume of the building is not considered. The second is to calculate the average air permeation amount through the gap between the doors and windows in each direction, and based on this, the heating system is used. Designed to achieve a certain guarantee rate.

2 ventilation times method

3 percentage addition method

For industrial buildings with high housing and high heat pressure, the additional heat consumption of the enclosure structure can be directly added to the total heat consumption of the enclosure structure according to the height of the room and the additional rate of the glass window layer.

Cold wind intrusion heat consumption

Less than wind pressure, hot pressing, the heat consumption caused by the opening of the outer door to the cold air is the cold air intrusion of heat. An additional amount of empirical method is usually included to calculate the basic heat consumption of the outer door.

Sodium bentonite waterproof blanket- GCL

Part one: Description of GCL waterproof blanket

Geosynthetic clay liners (GCLs) are high performance needle punched environmental reinforced composites which combine two durable Geotextile outer layers with a uniform core of natural sodium bentonite clay to form a hydraulic barrier. Fibers from the non-Woven Geotextile are needle punched through the layer of bentonite and incorporated into the other geotextile (either a woven or non-woven).when hydrated under a confining load, the bentonite swells to form a low permeability clay layer with the equivalent hydraulic protection of several feet of compacted clay.

Gcl

Part Two: Technical of GCL waterproof blanket

Part Three: The Application of GCL

This Bentonite production line is usded to bond 3layers of top geotextile, middle bentonite sand, and down plastic woven film.
The water proof bentonite pad is mainly used in penetration-proof,airproof &separation in rubbish burying square,man-made lake,channel,pool,basement,subway,etc.
The production line processing of finished products with high peel strength, strong pulling hardness, low permeability.
