It is also a constant temperature and humidity storage room for foods, liquid, chemical, pharmaceutical, vaccine, scientific experiments and other items. The refrigeration system of the cold room is still a core component of the construction of the entire Cold Storage Room.
2, Cold room classification:
According to the structure
â—‡ Civil engineering cold room building
â—‡ Steel structure cold room
â—‡ Mixed structure
Mobile cold room, Modular cold room and cold room container.
According to the cold room usage
â—‡ Production type cold room used in food, meat, fish factory
â—‡ Distribution type cold room used for logistics
â—‡ Retail cold room used for supermarket
â—‡ Household cold room

â—‡ Medium-sized cold storage 1000-10,000 tons
â—‡ Small cold storage less than 1000 tons
According to the cold room temperature
◇ High temperature cold room Chiller Room design temperature (-2~8°C)
◇ Medium temperature cold room design temperature (-10~-23°C)
◇ Low temperature cold room Freezer Room design temperature (-23~-30°C)
◇ Ultra-low temperature cold room design temperature (-30~-80°C)
According to the cold room goods
â—‡ Seafood and meat cold room
â—‡ Dairy and ice cream cold room
â—‡ Fruit and vegetables cold room
â—‡ Pharmaceutical and chemicals cold room
â—‡ Flower cold storage
3, Cold room refrigerant choice
â—‡Ammonia: the oldest in history, the best choice in the field of industrial refrigeration worldwide. Due to the characteristics of the ammonia system, it is generally used for centralized refrigeration, with a special machine room for large-scale refrigeration systems (more than 10,000 tons of cold storage). There is a trend toward miniaturization and modulation, with an emphasis on improving safety and reducing the amount of charging.
â—‡ Freon: It is widely used in cold storage to disperse refrigeration. It is suitable for small and medium-sized cold storage and large-scale cold storage with limited ammonia. For environmental protection, large-scale cold storage The Freon system should be avoided as much as possible.
â—‡ CO2: The cold storage application is mainly based on cascade system and loading system. The low-temperature field is more suitable for cascade. The high-temperature field is suitable for loading. The cascade system is more expensive than the traditional ammonia and Freon system.

How is a cold room designed?
A good design of these rooms considers not only the selection of equipment, but its location for a safe access of the personnel. To ensure a safe access and maneuver into the cold room, it is necessary that contractors, engineers and owners participate in the project to determine the selection of a cooling system determined by analyzing life cycle cost and energy efficiency.
As your cold room expert, more than 18 years refrigeration experience, from design to installation and maintenance service, we provide one stop cold storage service for your fresh life. Best practice for building cold storage and controlling energy saving. We are China leading manufacturers and suppliers of Cold Room Units,Freezer Room and Mobile Cold Room, and we are specialize in Modular Cold Room,Cold Room Container, etc.
NPC deputy urges public toilets in urban areas to increase the proportion of female toilets
NPC deputies appealed to urban public toilets to increase the proportion of women's toilets diesel generators | diesel generators price / 2012-03-09
Women's Day National People’s Congress representative Ye Ching Tat’s special recommendation for women
Urban public toilets should increase the proportion of female toilets
Yesterday (8th) was the 38th Women’s Day. The National People’s Congress representative from Wuhan and Ye Qing, deputy director of the Statistics Bureau of Hubei Province, submitted a special proposal to the conference group “Improve the design standards of public toilets in the city and improve female toilets. Bit Ratio.
In his proposal, Ye Qing pointed out that in many public places in China, such as tourist attractions, large shopping malls, and transportation hubs, men and women do not need to line up for toilets, while women wait for a long time in toilets and there is a stark contrast between the status of men and women toilets.
Ye Qing said that he often encountered this problem when escorting his wife to the shopping mall. The lady lined up in the toilet and he waited outside for his wife. As a man, Ye Qingxiao said that during the Women's Day, women should be given more care.
He introduced that the Ministry of Construction's "Urban Public Toilet Design Standards" implemented since December 2005 proposed that the ratio of male toilet seats (sitting and standing) and son-in-law (sitting) positions in public toilets should be 1:1 to 2:3. Public toilets in commercial areas should be 2:3. but
“Yes†means that this standard is not mandatory, leading to greater arbitrariness in implementation, and it cannot effectively protect women's equal rights to use the toilet.
Therefore, Ye Qing proposes to amend the "Standard" to obligate the public toilets to have a 2:1 ratio of women's toilet seats (squat and seated) and male toilet seats (squat, sit and stand), of which women's and men's toilets are The ratio of sitting (sit) must reach 4:1, female toilet
The area must also be increased accordingly, and at the same time require the local administrative departments (urban construction management departments) to earnestly implement enhanced supervision. If it cannot be reconstructed, an unisex bathroom (without gender toilets) should be added as appropriate.
