★How it works

A chiller is a refrigeration device used to produce low-temperature cold water, mainly to provide chilled water for air-conditioning systems or industrial production processes.

◆ Shandong Aike Holding Group Co., Ltd. is a comprehensive high-tech enterprise integrating scientific research, design, production, sales and installation. With its professional level and mature technology in the field of central air-conditioning systems, it has rapidly risen in this field.

◆ The main products include ventilation equipment, fresh air equipment, electromechanical equipment, fire smoke exhaust equipment, water tanks, cooling towers and other central air-conditioning systems, purification air-conditioning systems and terminal supporting products. Products are distributed all over the country.

◆ Strong cooling capacity

The chiller has powerful cooling capacity and a wide range of cooling capacity for a single unit. It can meet the cooling needs of buildings and industrial sites of various sizes and can provide cooling services for multiple areas or equipment at the same time.

◆ Precise temperature control

Equipped with advanced temperature control system, the cold water temperature can be controlled within a very narrow range according to actual needs, usually with an accuracy of ±0.5℃ or even higher

◆ High operating efficiency

By adopting efficient compressors, optimized heat exchanger design and intelligent control systems, the chiller can maintain a high energy efficiency ratio under different load conditions.

◆ High system integration

Chillers usually integrate compressors, condensers, evaporators, throttling devices and control systems into an overall framework to form a compact modular device. During installation, it only needs to be connected to the external cooling water source, chilled water system and power supply, which greatly reduces installation time and space requirements and facilitates maintenance and management.

★WORKING PRINCIPLE

◆ Compression process

The compressor is the power source of the entire refrigeration cycle. lt draws in the low-temperature, low-pressure refrigerant gas from the evaporator compresses it, and turns it into high-temperature, high-pressure refrigerant gas.

◆ Condensation process

The high-temperature and high-pressure refrigerant gas enters the con-denser.In the condenser, the refrigerant transfers heat to the cooling medium, it cools and condenses into a high-pressure liquid.

◆ Throttling process

The refrigerant in high-pressure liquid state passes through the expansion valve or throttle device.Due to the throttling effect of the expansion valve, the pressure the refrigerant drops sharply, and the temperature also decreases accordingly, turning into low-temperature,low-pressure wet steam or liquid.

◆ Evaporation process

The refrigerant, which is at a low temperature and low pressure,enters the evaporator and ex-changes heat with the water to be cooled. The refriger absorbs heat from the water, turning itself into a low-temperature,low-pressure gas, which in turn lowers the temperature of the water, producing cold water.
