Targeted Depending on the original ammonia refrigeration system characteristics, building structure, insulation characteristics, usage requirements (such as in logistics cold storage, which does not affect normal business warehousing), cost control and other aspects, we provide different scientific and reasonable refrigeration solutions and construction plans. There are currently four main ammonia warehouse renovation plans:
The first one: Transform the original ammonia refrigeration system into a fluorine refrigeration flooded liquid supply ethylene glycol system
Retain the original indoor heat exchanger, such as the ceiling in the warehouse The heat exchange evaporator equipment such as exhaust pipes, quick-freezing shelves, air coolers, spiral evaporation tubes in the ice making system, etc. is just to replace the refrigeration host equipment with our company's special refrigeration unit to prepare low-temperature secondary refrigerant and transport it to the indoor heat exchange The device performs heat exchange to reach the set temperature. It has the characteristics of simple construction, short conversion period, convenient pipelines and low cost. The temperature range can be carried out from +℃ to -℃. Using brine for indirect refrigeration, there are no problems such as difficulty in oil return, easy leakage of refrigerant, difficulty in detecting leaks, uneven liquid distribution in direct evaporation systems. Only regular maintenance of the refrigeration host is required, with low failure rate and low maintenance costs. Province. The equipment can realize energy adjustment according to the actual load of the cold storage, and at the same time supply liquid through the freezing pump. There is no problem such as pressure loss, cooling capacity loss, difficulty in controlling parameters, etc. It has strong controllability and a high overall energy efficiency ratio.
The second type: the original ammonia refrigeration system is changed to a fluorine barrel pump liquid supply refrigeration system
Suitable for various types of spiral quick freezers, tunnel single freezers, air-cooled quick-freezing warehouses and other refrigeration systems, or The original ammonia cold storage exhaust pipes were replaced with a fluorine exhaust pipe system. The transformed refrigeration system has the characteristics of high energy efficiency, system stability, and convenient management.
The third type: the original ammonia refrigeration system is changed to a small air-cooled Freon refrigeration system
Some workshop air-conditioners and small cold storages used in ammonia systems are transformed into small air-cooled Freon refrigeration systems. The refrigeration system is simple and prone to malfunctions. The efficiency is low, each system is in opposition to each other, and the energy saving effect is obvious.
The fourth method: the original ammonia refrigeration system is changed to use the ammonia system as the cold source and ethylene glycol enters the terminal system
Keep the original cold source unchanged, and add a horizontal evaporator and an ethylene glycol water pump to supply water. to the end cooler. This is also the most affordable renovation option currently.
