Product Description:

PCM refrigeration system for Mine refuge chamber

Refrigeration PCMs Used in Refuge Chamber


Phase Change Material (PCM) refers to a kind of substance that can store latent heat and can change its form when the temperature changes. It is called Phrase Transition when the material changes from solid to liquid and vice versa, during which the PCM will absorb or release large amounts of latent heat. PCM consists of organic and inorganic PCMs and all of the PCMs referred to in this Article belong to inorganic ones.


 

Environment of Refuge Chamber and Requirements for PCMs


To prevent CO and other toxic gases infiltrating into the chamber, airtight and positive pressure structure is usually applied in the refuge chamber. Temperature and humidity will gradually rise when people get into the chamber. To meet the requirements with the temperature lower than 35°C and the humidity less than 85%, dehumidify and cooling should be conducted in the refuge chamber. 


Temperature in the refuge chamber (capsule) should not exceed 35°C and the melting point of PCMs should stay 24-27°C.


The most important technical parameter of PCMs is latent heat. Resulting from the small and limited space in the chamber, PCMs with no scent, high latent heat, high density and suitable melting point are required.   
- Latent heat: equal to or larger than 350 KJ/KG;
- Density: equal to or larger than 1.38 G/ML;
- Without pungent odor (i.e. ammonia) when PCM is in its solid phrase or being heated;
- Melting point of PCMs stays 24-27°
C.



PCM Consumption


Average power of human body is about 200 W and it is around 75 W when sleeping or watching TV. 24-hour metabolism of each person is 11.88 MJ. In case that the latent heat of PCMs is 350 KJ/KG, daily consumption of PCMs is 34 KG and 136 KG for four days. Hence, PCM consumption can be evaluated by the number of people.



PCM Cooling Solutions for Refuge Chamber


Aluminum Foil Bag Packing
Put the PCMs packaged with aluminum foil bags in the metal box (mainly 304 stainless steel) and put the box in the refuge chamber. Usually, wind-cooling or water-cooling methods are utilized to crystallize liquid PCM. In case of accidents, ambient temperature of the refuge chamber rises and makes the PCMs melt while absorbing heat, thus to achieving the target of controlling temperature around a favorable range.  
PCM packaging:
Bag size: 16 * 31 cm 
Weight: 500 g/bag

 


PCM Bags Hanging on the Stands


A string of connected PCM bags are hung on the stands, stand sizes are designed according to the chamber size, and these stands can be moved to wherever you want.

Q:What is the relationship between the futures price and the price of oil futures and other energy futures?
Second: not too much, between the silver gold and iron ore and other difficult exploitation of energy futures and oil related, such as silver prices, increased mining costs, as oil prices fall, but the decline is very small, the oil futures still pay more attention to the world's oil inventory the data is more important.
Q:What is the general energy?What do we usually say about energy conservation?
Chapter I General ProvisionsArticle 1 this law is enacted for the purpose of promoting energy conservation, improving energy efficiency and economic efficiency, protecting the environment, ensuring the development of the national economy and society, and meeting the needs of the peopleSecond energy resources referred to in this Law refers to coal, crude oil, natural gas, electric power, coke, coal gas, heat, refined oil, liquefied petroleum gas, biomass energy and other directly or through processing, conversion and made useful to the various resources.
Q:China's new energy marketing plan
Two, the determination of research methodsThree, work planFour, pending buyers survey quotaIn five, the second-hand inquiry collectionSix, cost budget and detailSeven, research quality control
Q:Rapid rise in petrochemical products and energy prices
Therefore, the rapid rise in the prices of petrochemical products and energy may have the greatest impact on the profitability of chemical drugs manufacturing.The correct answer is D.
Q:What is the cost effectiveness ratio of energy management in energy quality?
The laws of the state set the maximum value for the former, which set the minimum value; as a rigid index of energy efficiency regulationsAlthough different countries have different national conditions according to different national conditions, these two points are regarded as the final judging index
Q:What is mobile energy? A new kind of energy? There is no actual product?
As for mobile energy products, it is recommended that you can search for a mother's film innovative product competition, look, there are many interesting things.
Q:What is terminal energy consumption
1 as fuel, power use of energy refers to the energy into a variety of heating, power and other equipment, the production of light, heat, power consumption of energy2 as the raw materials used in industrial production. Energy refers to energy activities, as raw material is put into use, after a series of chemical reactions, gradually transformed into a new non energy products, such as chemical fertilizer plant for the production of synthetic ammonia, chemical factory production of synthetic rubber products such as the consumption of natural gas and coal coke consumption; production of dyes, plastics, textile products of raw oil.
Q:What is a one-time energy
Primary energy: refers to the natural form of the original form, the conversion of energy resources without processing. Natural energy.
Q:State approved products called new energy foods
New resource food management approach provides that the new resource food has the following characteristics:Animals, plants and microorganisms in China without eating habits;(two) new varieties of microorganisms used in food processing;(three) because of the use of new technology to produce food ingredients that result in changes in the original composition or structure.
Q:What are the economic operating standards for energy equipment and systems?
Ten measures to build a resource-saving societyThe party's the fourth Plenary Session of the 16th CPC Central Committee through the "CPC Central Committee on strengthening the party's ruling ability construction decision" to "pay attention to family planning, to save resources, protect the environment and production safety, vigorously develop the circular economy and building a conservation minded society", as the important content of the party continuously improve the ability to control the socialist market economy, to further strengthen the party's ruling of our party capacity building, pointed out the direction. This is to accelerate the construction of resource-saving society, promote the development of circular economy, taking a new road to industrialization, to ease the bottleneck of resources, solve the well-off society facing resource constraints and environmental pressures, to ensure that major initiatives continued rapid and healthy development of the national economy, far-reaching significance.
