Four major concerns about buying a chiller

The chiller is a water cooling device. The small chiller is a cooling water device that can provide constant temperature, constant current and constant pressure. The working principle of the small chiller is to inject a certain amount of water into the water tank of the machine through a small chiller. The refrigeration system cools the water, and then the low-temperature cooling water is sent to the equipment to be cooled by the water pump. The chilled water of the small chiller takes the heat away and then the temperature rises and then flows back to the water tank to achieve the cooling effect. The cooling water temperature can be automatically adjusted according to requirements. Long-term use saves water. Therefore, the small chiller is a standard energy-saving device. The operation of the chiller system is through three interrelated system refrigerant circulation systems, water circulation systems, and electrical control systems. The refrigeration system consists of basic components such as a compressor, a condenser, an evaporator, a liquid reservoir, a drying filter, a throttling device, and a refrigerant. 1. The chiller is divided into three types of air-cooling: it is suitable for machine-side cooling and centralized cooling. It does not need to add water tank and water pump. It does not need water tower to dissipate heat. It requires high air mobility in the environment. Water-cooled box type: suitable for machine Side cooling and concentrated cooling, no need to add water tank and water pump, and need water tower cooling water cooling open type: temperature control machine is suitable for larger type of concentrated cooling, need to add insulation water tank and water pump, and need water tower cooling

Second, the choice of machine size for the injection molding machine mold cooling, can be calculated according to the injection volume of the injection molding machine. In general, every 6 ounces of injection volume requires 1HP chiller.

For example: the customer factory is 3 sets of 100T (5.5OZS), 4 sets of 150T (12OZS), 3 sets of 200T (23OZS), and the required chiller size is (5.53+124+233)6=22.25, which means 25HP is required. The chiller. When used for cooling other equipment, it depends on the specific flow rate of the cooling water circulation.

Third, the selection of the chiller's insulation tank and pump sometimes according to the actual situation of the customer's factory, the box type chiller may also need an external pump, at this time the added pump model must have the same pump power in the chiller. For example, 10HP The water quality of the box type chiller comes at 2HP. When the pump is added, it must also be 2HP. The open type chiller. When the external pump is used, the pump power requirement is the same as that of the same type of box chiller.

Fourth, the temperature of the chiller return water, it is best not to be higher than 40 degrees, the higher the return water temperature, the greater the damage to the compressor.

The chiller is mainly used in the plastics industry: plastic molding, injection molding, extrusion molding, blowing, thermoforming, machinery industry: laser technology, welding, mechanical cutting, non-cutting, casting, electroplating, electronics industry: surface treatment, electroplating , electrophoresis, medical equipment, electronics industry, circuit board production, electronic chip manufacturing, chemical industry and other industries: chemical, paper, pharmaceutical, food processing, aluminum profiles, aluminum alloys, tempered glass, coated glass production, ultrasonic cleaning冼, jewelry processing, leather, fur processing, ink production, aquaculture.
