<P>PROBLEM TO BE SOLVED: To provide a heat pump device capable of improving reliability of read data and write data of a non-volatile memory card without increasing costs. <P>SOLUTION: This heat pump device has operation modes including at least a heating mode, and stores various information relating to an operation in the non-volatile memory card. The heat pump device includes: a card slot 103 for inserting the non-volatile memory card; and a control section 101 estimating the temperature of the non-volatile memory card inserted into the card slot 103 on the basis of the operation mode, a set temperature in the operation mode, and part temperatures including an indoor temperature, an outside air temperature and a discharge temperature of a secondary refrigerant, and writing and reading the various information several time by the number of times more than that in a case when the estimated temperature of the non-volatile memory card is higher than a lower limit value of an operation guarantee temperature, when the estimated temperature of the non-volatile memory card is less than the lower limit value of the operation guarantee temperature. <P>COPYRIGHT: (C)2013,JPO&INPIT |
