HEAT SOURCE APPARATUS, HEAT SOURCE SYSTEM, AND METHOD FOR OPERATING HEAT SOURCE APPARATUS
First Claim
1. A heat source apparatus comprising:
- an electric compressor that is driven by an inverter device and that compresses a refrigerant, the inverter device having a protective function that performs stoppage for device protection on the basis of a predetermined calculation by an inverter control portion;
a condenser that condenses the refrigerant compressed by the electric compressor;
an expansion valve that expands the refrigerant condensed by the condenser;
an evaporator that evaporates the refrigerant expanded by the expansion valve; and
a control device that controls cold output and/or heat output,wherein the control device includes an inverter-protective-function estimating unit that estimates a calculation result of the protective function of the inverter control portion.

Abstract
A heat source apparatus in which a control device of the heat source apparatus can ascertain a stoppage of an inverter device and in which a stable operating time of the heat source apparatus can be extended is provided. The heat source apparatus includes an electric compressor that is driven by an inverter device and that compresses a refrigerant, the inverter device having a protective function that performs stoppage for device protection on the basis of a predetermined calculation by an inverter control portion, and a control device that controls cold output and/or heat output. The control device includes an inverter-protective-function estimating unit that estimates a calculation result of the protective function of the inverter control portion.
