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.
-
NewsWith precision machining, compressor assembly, pressure vessel production, unit assembly, cold storage equipment production and other modern assembly lines and 4 sets of product performance testing platform, with an annual output of more than 3000 sets of screw products (sets) capacity.
-
CasesThe screw machine produced by Wuleng is widely used in petroleum, chemical industry, air conditioning, refrigeration, hydropower, textile, coal, pharmaceutical, food, beer, sports venues, exhibition centers, marine refrigeration, national defense science and technology and other fields. It has also entered the international markets of Africa, Oceania, South America and Southeast Asia.
-
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.
Cascade high temperature heat pump
Classification:
Key words:
Cascade
Summary Introduction
Heat pump system: the low-temperature heat source is the compressor exhaust of the original refrigeration system. Part of the exhaust gas is separated from the exhaust gas of the refrigeration system and enters the condensing evaporator of the heat pump unit for condensation. The condensed ammonia liquid is throttled and then industrially converted to the ammonia low-pressure refrigeration system. The evaporation side of the condensing evaporator is the heat pump working medium. The heat pump working fluid absorbs the heat of ammonia condensation and evaporates into gas, which is sucked and compressed by the heat pump compressor. The high-temperature exhaust gas of the heat pump compressor enters the heat pump condenser for condensation. After the economizer, it expands and throttles to the condensation evaporator for evaporation and repeats the cycle.
