Chiller is a kind of water cooling equipment, which is a cooling equipment capable of providing constant temperature, constant current and constant pressure. The principle of the chiller is to inject a certain amount of water into the internal water tank of the machine, and the water is cooled by the chiller refrigeration system, and then the water pump inside the machine injects low-temperature frozen water into the equipment that needs to be cooled. The chilled water will heat the inside of the machine. Take it away, and return the hot water with high temperature to the water tank again to lower the temperature. In this way, the cooling is cyclically exchanged to achieve the function of cooling the equipment.
Industrial chiller is a kind of chiller, which can be divided into air-cooled chiller and water-cooled chiller.
Industrial chiller typically comes as a complete packaged closed-loop system, including hot and cold water units, condensers and circulation pumps, expansion valves, no-flow shut-off, internal cold water tanks, and temperature control stations. The internal tank helps maintain cold water temperature and prevents temperature spikes. Closed loop industrial chiller recirculates water-cooled equipment and instrument cleaners and conditions at constant temperature and pressure, increasing stability and repeatability.
Air-cooled The air-cooled chiller uses the shell and tube evaporator to exchange heat with water. The refrigerant system absorbs the heat load of the water, cools the water to produce cold water, and then brings the heat to the fin condenser through the role of the compressor. It is dissipated into the outside air by the cooling fan. Features: 1. The air-cooled chiller does not need to be connected with a cooling water tower, which is suitable for environments with poor impurities. (Contaminants are easily mixed in the cold water tower, and the cooling water circulation circuit is blocked by dust, which reduces the cooling capacity). 2. Air-cooled chiller is most suitable for areas with poor water quality and can save other accessories for cold water towers. 3. It adopts large-capacity condenser, which can be operated easily even in hot weather. 4. Minimize the floor area and easy installation. 5. The air-cooled chiller adopts a top-out air design.
Water-cooled The water-cooled chiller uses a shell and tube evaporator to exchange heat with water. The refrigerant system absorbs the heat load in the water, cools the water to produce cold water, and brings the heat to the shell and tube condenser through the role of the compressor. The refrigerant exchanges heat with water, so that the water absorbs the heat and dissipates the heat outside the cooling tower through the water pipe. Features: 1. High-quality compressors are the heart of industrial chiller (new original compressors from Europe, America and Japan, with built-in safety protection, low noise, power saving and durable). 2. The box-type evaporator has a built-in automatic water replenishing device, which eliminates the need for the Peng expansion water tank in the engineering installation for easy installation and maintenance, and is suitable for special occasions such as large temperature differences and small flows. 3. The water-cooled condenser is made of the latest high-efficiency externally threaded copper tube, which has a large heat dissipation and a small size. The latest CAD / CAM processing technology is used in conjunction with the production of CNC machining center. It has a compact structure, high reliability, beautiful appearance, high efficiency and energy saving. 4. Configuration of industrial chiller unit: equipped with a single-chip control system, built-in compressor dryer filter and expansion valve, maintenance hand valve interface and other devices, ensuring reliable and safe operation of the machine and convenient maintenance. 5. The multifunctional operation panel of the industrial chiller is equipped with an ammeter, control system insurance, compressor switch button, water pump switch button, electronic temperature controller, various safety protection fault lights, unit start operation indicator, simple operation and convenient use . Industrial chiller unit configuration: equipped with a single-chip control system, built-in compressor drying and expansion valve, maintenance hand valve interface and other devices to ensure reliable and safe operation of the machine and facilitate maintenance and repair.
Screw type The screw chiller is named as the screw chiller because of its key component. The compressor is a screw chiller. The unit is a gas refrigerant from the evaporator. After the compressor is adiabaticly compressed, it becomes a high temperature and high pressure state. The compressed gas refrigerant is cooled and condensed in the condenser under constant pressure. After the condensation, it changes to a liquid refrigerant, which is then expanded to a low pressure by a throttle valve and becomes a gas-liquid mixture. Among them, the liquid refrigerant at low temperature and low pressure absorbs the heat of the material to be cooled in the evaporator, and becomes a gaseous refrigerant again. The gaseous refrigerant re-enters the compressor through the pipeline and starts a new cycle. These are the four processes of the refrigeration cycle and the main working principle of the screw chiller.
Water chiller is widely used in plastics, electroplating, electronics, chemicals, pharmaceuticals, printing, food processing and other industrial freezing processes where frozen water is used, or it can also be used for villas, restaurants, hotels, institutions, schools, factories, etc. Space provides comfort in the air-conditioned area.
