The advantages of adopting shell-and-tube condenser and evaporator in industrial chiller products include simple structure, easy maintenance and high heat transfer efficiency. For example: "Stable Dai chiller" series of products are used in the company's unique design shell and tube condenser, evaporator. Its heat transfer performance is more than 20% higher than ordinary products, and less cold loss, easy to return to the oil, the heat transfer tube will not freeze. We all know that compressor is the core part of industrial chiller operation, its role is no less than the human "heart". The refrigeration compressor used by "Stable Dai" is mainly the high quality compressor imported from abroad. Advantageous brand products can add points to the normal and stable operation of industrial chiller, and safety and power saving, long service life, and no noise, very suitable for use in the central air-conditioning and other fields. General use of water cooling (i.e., natural water and water tower cooling method of two ways) can not achieve high precision, high efficiency control of the temperature of the purpose, because the natural water and water tower cooling are inevitably affected by the natural temperature of the water temperature in winter and high water temperature in summer. If the air temperature in the case of 30 ℃, to water temperature to 10 ℃, which is almost impossible, so with this way of control is extremely unstable. Chiller and general water cooling equipment is completely different, because the chiller has a completely independent refrigeration system, will never be affected by the temperature and the environment, the water temperature in the range of 5 ℃ ~ 30 ℃ adjustment and control, and thus can achieve high precision.
