Japan introduced heat pump balance control technology precision air conditioner

Orion Machinery (Headquarters: Suzaka, Nagano Prefecture, Japan) has developed a thermostatic control technology called "heat pump balancing control" that can reduce power consumption by more than 70% compared with the original method. The company has a "PAP" series of precision air conditioners using the technology and a "PEC" series of Chiller. It is used for the following purposes: Adjusting the temperatures of devices and workpieces during precision machining such as precision molds and spherical machining. In the semiconductor protective layer coating process, the surrounding environment and the temperature of the protective liquid are adjusted to ensure the film thickness accuracy.

The company developed heat pump balance control technology, the use of household water heaters and other heat pump cycle used. In general, the heat pump cycle absorbs heat from one side and discharges heat to the other side to perform one-way circulation of heating. In the new technology, a heating mechanism and a cooling mechanism are provided in the additional heating heat exchanger, and one compressor is used A continuous refrigeration cycle. Eliminating the need for temperature control with electric heaters.

In addition, by the improvement of the piping system and the control technology, the refrigerant is divided more evenly, and therefore, it can be controlled according to the change of the generated heat. With a power consumption of 3.2kW, it saves 73% more energy than a PID-controlled precision air conditioner with electric heaters. As for the refrigerator, it is equipped with a DC brushless motor that has been used in previous products, thereby increasing the efficiency by about 30% over that of a refrigerator equipped with an AC servomotor.

For the PAP series, there are 3 models with air flow rate of 5/10 / 20m3 / min, with or without HEPA filter. The price is 2,020,000-6,040,000 yen (tax included). The above products can be in the range of 18 ~ 30 â„ƒ, with Â± 0.1 â„ƒ accuracy control temperature. In addition, the price of PEC series products is 1,722,000 yen (tax included). Can be controlled at Â± 60 Â° C with Â± 0.05 Â° C accuracy.

Slag Pot

The slag pot covered here is a load-bearing device whose sole purpose is to collect molten or solid slag generated during metallurgical or chemical processes, to retain it during transport and to deposit it at a place of disposal.
Slag Pots are crucial items as they are part of a lifting equipment and therefore undergo in terms of mechanical design engineering and handling the national safety regulations of the state where they are supposed to be operated.
