The main components and performance characteristics of the Toyota screw chiller are as follows:
1. Compressor: It mainly chooses the original screw compressor of Taiwan Hanzhong brand, which has many advantages such as compact structure, small size, light weight and small installation position. The compressor uses a 5:6 ultra-efficient screw rotor with no direct wear between the rotors and high reliability. And with four-level capacity control system energy adjustment: 100%-75%-50%-25%, according to load changes, self-regulating unit start and stop, more energy efficient. During operation, the computer control system changes the energy output of the chiller based on changes in the thermal load of the client.
2. Evaporator: The shell-and-tube evaporator used by the company is independently designed and manufactured by the internal thread type high-efficiency heat exchange copper tube. The outer surface of the copper tube is spirally smooth and the water side baffle adopts a non-short circuit design, which has good cooling effect, and has the advantages of high heat exchange efficiency, compact structure, stable and long-lasting heat exchange performance, reliable oil return and easy maintenance. The evaporator body is insulated by a 25mm thick PE insulation board, which does not condense and has less loss of cooling capacity. The chilled water mixing heat exchange efficiency is improved.
3. Condenser: The shell-and-tube condenser is manufactured by different types of heat exchange copper tubes imported and domestically produced. The outer surface of the copper tube is processed into trapezoidal low ribs, which increases the heat exchange area and enhances heat transfer performance. The inner surface of the copper tube is smooth, which reduces the water pressure and is easy to clean and maintain.
4. Protection device: The chiller is equipped with compressor delay start protection, overload protector, high and low voltage protector, temperature control switch, antifreeze switch, fuse plug, electronic time protection safety valve, compressor overheat protector, compressor frequently Start the protector and abnormality indicator to ensure the normal operation of the chiller.
5, computer control system: select the United States Bangpu brand microcomputer Chinese digital control panel, can do remote monitoring and control. The operation is simple, the host and the power supply are connected, the failure rate is low, the safety factor is high, the installation is simple, the system control can be adjusted instantly, and is intuitive and reliable.
