AboutWuhan New World Refrigeration Industry Co., Ltd. (hereinafter referred to as "Wu Leng"), formerly known as Wuhan refrigerator factory, was established in 1954 and has a history of nearly 70 years. It was originally one of the large backbone enterprises under the Ministry of machinery industry, and is now one of the core enterprises of Dalian Bingshan Group.
-
ProductsScrew refrigeration compressor, a traditional refrigeration product of Wuleng, has the characteristics of small size, high efficiency, low energy consumption, few wearing parts, high stability and long service life. Since the successful development of the first screw machine in 1978, Wuleng has produced more than 60000 screw machines (sets) and is one of the large backbone enterprises in China's air conditioning and refrigeration industry.

RecruitThe company has also developed new high-efficiency and energy-saving products such as skid-mounted mobile natural gas pressurization, natural gas liquefaction devices, ultra-low temperature cascade units, low-pressure screw blowers, and high-efficiency oil fume purifiers, which contribute to the development of national energy conservation, emission reduction and green environment.
-
ContactAfter decades of unremitting efforts, the screw machine developed and produced by Wuleng has won all the national awards for such products for many times, and presided over or participated in the drafting of the national and industry standards for screw machines. It is the vanguard of the domestic screw machine industry.
Mine waste heat recovery, waste air, water heat pump system
Classification:
Key words:
Mine waste
Summary Introduction
Vent air source heat pump and gushing water source heat pump system: extract heat from the mine return air (or gushing water) to the heat exchange circulating water of the system, and use the high temperature heat pump unit for heating. In winter, heat is absorbed from the return air (or gushing water) of the mine at about 15 ℃, and hot water at 45 ℃ ~ 60 ℃ is produced for heating and heating. In summer, if there is a demand for cooling, the system can also reverse the cycle to provide air conditioning chilled water for cooling. The system can extract 3 ~ 5kW of low-grade heat energy from the mine return air while consuming electricity per degree, producing a total of 4 ~ 6kW of heating capacity.

The system can extract 3 ~ 5kW of low-grade heat energy from the mine return air while consuming electricity per degree, producing a total of 4 ~ 6kW of heating capacity.
The heat pump system can produce high temperature hot water in winter, which can not only meet the demand of wellhead fresh air heating, but also meet the demand of heating water and bathing hot water in mining area. It can optimize the utilization of energy in mining area.
The hot end adopts the exhausted air heat box, and the fresh air side adopts the fresh air heat exchanger. The unit is modular, highly integrated and adapts to a wide range of working conditions.
The heat extraction box can realize double-stage or even multi-stage heat extraction, so that the temperature of the exhausted air after heat extraction is gradually reduced to below zero.
The exhausted air heat box can realize automatic defrosting.
High temperature heat pump unit adopts brand semi-hermetic compressor. Our company has decades of experience in unit integration, with hundreds of sets of supporting capacity each year, advanced technology and reliable performance.
