Claims

[Scope of Claim for Utility Model Registration] (1) A compressor whose operation is controlled by a starter panel, a temperature sensor and a pressure sensor provided on the discharge side of this compressor, and a system that saturates the pressure detected by this pressure sensor. In addition to converting into temperature, the difference between the temperature detected by the temperature sensor and the saturation temperature is calculated, and when this temperature difference becomes a predetermined temperature or less, a command to stop the compressor is output to the start panel. Refrigeration and air conditioning equipment equipped with a controller. (2) The controller includes an input section that takes in the outputs of the pressure sensor and temperature sensor, an A/D converter that converts the data of these input sections, a storage section that stores the data of this A/D converter, and a memory section for these. A practical device characterized in that it is composed of an arithmetic section that calculates and judges the values of the parts, an output section that outputs commands from these arithmetic sections to the starting panel, and a display section that displays the values of these output sections. A refrigeration and air conditioner according to claim 1 of the patent registration claim.
