Mingtong Industrial Chiller, Air-Cooled Industrial Chiller

Industrial Chiller Working Principle: The chiller operates on the same refrigeration principle as typical refrigerators. The compressor compresses the low-pressure refrigerant into a high-pressure vapor, reducing its volume and increasing its pressure. The compressor draws in the lower-pressure working refrigerant from the evaporator, increases its pressure, and sends it to the condenser. In the condenser, the refrigerant condenses into a high-pressure liquid. After passing through a throttling device, it becomes a low-pressure liquid and is sent back to the evaporator. In the evaporator, the refrigerant absorbs heat and evaporates, becoming a low-pressure vapor again, which is then sent back to the compressor to complete the refrigeration cycle. The evaporator typically contains a medium (usually water or a water solution), which is then circulated by a pump to the equipment that requires cooling. After the chilled water removes heat, it returns to the reservoir, achieving the cooling effect. The chilled water temperature can be automatically adjusted to meet requirements, and long-term use can save water.

Industrial Chiller Selection: Due to the underdeveloped domestic industry in the early days of liberation, chillers were primarily used in air conditioning units and state-owned enterprises, with most being foreign brands. Therefore, they were mainly for civil use. After the reform and opening up, the industry developed rapidly, with increasingly high requirements, leading to the emergence of various specifications of units, such as: the air conditioning工况 typically has an outlet temperature of 7 degrees, but industrial use can vary in temperature, including medium-high, medium-low, low-temperature, and ultra-low-temperature types. Consequently, various names have emerged like: chiller, refrigeration unit, ice water unit, and cooling machine. Our company specializes in producing various specifications and temperature chillers, including shell-and-tube, water tank, titanium alloy, stainless steel, open-type, split-type, cascade low-temperature, screw-type, evaporative, explosion-proof, high-temperature high-capacity, and magnetic levitation models, suitable for different environments. The temperature range is from 25 degrees to minus 100 degrees for customer selection.

Key Features of Industrial Chiller:

(1) We select original brand compressors, including high and low-temperature models from Copeland (Gulley) in the U.S., Metro Compressor (Meyoule) in France, Bizel (Bizer) in Germany, and Hanbell in Taiwan.

(2) Utilize refrigerants such as R404A, R410a, R22, R407C, R507, etc., to meet refrigeration temperature and environmental requirements; wider range

(3) Temperature Range Selection: Offers process refrigerants from -25℃ to -85℃ (users can select different unit specifications with varying outlet temperatures based on their specific production requirements)

(4) Depending on customer requirements, various refrigerants (cooling water) can be selected: ethylene glycol solutions, alcohol, ternary mixed solutions, and other alcohols as refrigerants. The evaporator can also be designed to meet anti-corrosion requirements, using calcium chloride solutions; hydrochloric acid solutions, Liu Shuan solutions, etc.

(5) Designed for 24/7 continuous operation, it can meet the cold source requirements for various continuous production processes.

(6) The unit comes with its own water tank and circulating pump for cooling capacity, eliminating the need for a cooling tower and cooling pump, making installation and maintenance simple and convenient.

(7) Visual Microcomputer Control System: A comprehensive control system with a visual, touch-screen human-machine interface for real-time monitoring of the unit's operating status and automatic adjustment of energy output based on actual load changes. The control box is pre-equipped with multiple connection points and spare connection points for user remote transmission lines, remote control alarm lines, and other control lines. It also features protection functions such as overheating of compressor coil temperature, excessively low chilled water outlet temperature, high exhaust temperature, frequent compressor start/stop, abnormal voltage, etc. It includes control functions like scheduled on/off, operating time limitation, scheduled on/off, oil pre-heating, fault self-diagnosis, and fault reset. It also monitors compressor exhaust temperature, ambient temperature, return water temperature, and outlet water temperature.
