Document Type and Number:
Japanese Patent JPH01179865
Kind Code:
A
Abstract:
PURPOSE:To reduce the overall size and cost by providing a card data input/ output unit for a readable and writable card as well as a selecting means between a setting card and a record card. CONSTITUTION:In a refrigerating capacity/temperature control unit 9a, a control temperature determinating means 5 selects the control temperature from either the delivered air temperature or the inlet air temperature, and such control temperature is temporarily stored in a storage means 6. The card data are read from a card data input/output unit 1 by means of a card data reading means 2. Then, a card selecting means 3 determines as to whether the subject is a set card or a record card. When it is identified that a set card is in place, the set temperature is determined by a set temperature determining means 4, and a refrigerating plant control means 8 regulates the opening of an electronic regulator valve 14 so that the control temperature may correspond with the set temperature. If the identification made is that a record card is in place, the data in the memory means 6 is written in the card via the input/output unit 1 by a card data writing means 7.
