Our compressor control equipment estimates refrigeration limit of a blower of a forced air system for cars. All estimating items make blower control and estimation to limit count and information posting are handled consequently. The estimation time is abbreviated by progress of control strength and figuring process. In our compressor control equipment, profoundly exact limit estimation is empowered by exact estimation and count framework. It has an amazing repeatability and limit correlation of models which is done easily. this is fit for OCR estimation continuously. It has measurement System that includes mechanical efficiency, volume, performance coefficient, shaft horse power, net refrigeration capacity and many more.
