Title: Operation control device for air conditioner
Inventor: INOUE TSUGUNORI
IPC: F25B1/00
Filed: 1992-06-03
Abstract: PURPOSE:To avoid a wetting operation and an anti-freezing operation in an air conditioner for controlling a degree of opening of an electrical expansion valve in such a manner that a temperature of discharged refrigerant becomes a temperature giving the most suitable freezing effect. CONSTITUTION:The most suitable temperature Tk of discharged refrigerant is calculated by the most suitable temperature calculating means 51 in reference to an evaporating temperature Te of the refrigerant as well as its condensing temperature. A degree of opening of the electrical expansion valve is controlled in such a manner that a discharging pipe temperature Td reaches the most suitable temperature Tk by a degree of opening control means 52. The most suitable temperature Tk is restricted to show a higher value than its lower limit temperature (60 deg.C) by a target value limiting means 53. With such an arrangement, an over-opening of a degree of opening of the electric expansion valve is restricted and a wetting operation caused by an erroneous sensing of a condensing temperature is prevented. In the case that an outdoor air temperature Ta is lower than a predetermined value (5 deg.C), the lower limit temperature is changed by a lower limit temperature changing means 54 to become low as the outdoor air temperature is decreased. With such an arrangement, a starting of anti-freezing operation caused by over-reduction of the evaporating temperature Te is avoided.

Filed: 1980-10-13
Abstract: PURPOSE: To prevent the generation of alternant sound and a break of sound, by preventing the underflow and overflow states of a buffer memory by detecting the jitters of data exceeding the capacity of a jitter absorbing buffer memory.  
     CONSTITUTION: For example, the value of the number D of significant data is between O and G (G: an integer <2N-1), a decoder 40 recognizes that a memory is about to be in an underflow state, and outputs a signal to an underflow flag 42, which is set. Then, an RA counter count-up signal 51, while a low-frequency RA counter count-up signal 52a is sent, has the frequency set lower than that of a data readout synchronizing signal 49 from an RAM32. Consequently, the same data is read twice unlike normal operation, but they are in a continuous signal, so that the generation of alternant sound and a break of sound are prevented.
