摘要： A heat pump device includes a compression mechanism for compressing refrigerant, a motor for driving the compression mechanism, a shell housing the compression mechanism and the motor, a discharge muffler located outside the shell, a first pipe connecting the compression mechanism to the discharge muffler, and a thermal insulator (a first thermal insulating material and a second thermal insulating material). The shell and the discharge muffler are spatially located next to each other without being in contact with each other. The thermal insulator is at least partially located in a space where a distance between an outer surface of the shell and an outer surface of the discharge muffler is minimum.

摘要： A heat pump device includes: a compression mechanism for compressing refrigerant; a motor for driving the compression mechanism; a shell housing the compression mechanism and the motor; a discharge muffler located outside the shell, a first pipe which connects the compression mechanism to the discharge muffler; a first heat exchanger which includes a refrigerant inlet and which exchanges heat between the refrigerant and a heating medium; and a second pipe which connects the discharge muffler to the refrigerant inlet of the first heat exchanger. The shell and the discharge muffler are spatially located next to each other. The discharge muffler and the first heat exchanger are spatially located next to each other. The discharge muffler is at least partially located in a space between the shell and the first heat exchanger.

摘要： A water heater control system includes: a photovoltaic power generator interconnected with a commercial power supply, an electrical load circuit including a storage-type electric water heater using power from the commercial power supply and generated power of the photovoltaic power generator to perform a water heating operation of heating low temperature water to high temperature water and storing the high temperature water, and a HEMS controller limiting a water heating operation of the storage-type electric water heater by stopping or suppressing the water heating operation of the storage-type electric water heater when a power fee data for purchased power supplied to the electrical load circuit from the commercial power supply exceeds a standard monetary amount.

摘要： A heat pump system includes: a compressor for compressing refrigerant; a first heat exchanger for exchanging heat between the refrigerant compressed by the compressor and a heating medium; a second heat exchanger for exchanging heat between the refrigerant compressed by the compressor and the heating medium; a first pipe through which the refrigerant is fed from the compressor to the first heat exchanger; a second pipe through which the refrigerant returns from the first heat exchanger to the compressor; a third pipe through which the refrigerant is fed from the compressor to the second heat exchanger after returning from the first heat exchanger; and switching apparatus for switching a flow of the heating medium between a first mode and a second mode. The heating medium flows through the first heat exchanger and the second heat exchanger in series in the first mode. The heating medium flows through the first heat exchanger and the second heat exchanger in parallel in the second mode.

摘要： A heat storage system includes a compressor that compresses refrigerant; a heat storage tank that stores a heating medium; heat exchange means provided outside the heat storage tank for heating the heating medium using heat of the refrigerant compressed by the compressor; a heat accumulating circuit including a feed path that feeds the heating medium flowing out of the heat storage tank to the heat exchange means, a return path that returns the heating medium heated by the heat exchange means into the heat storage tank, and a pump that circulates the heating medium; and control means capable of executing an initial operation that controls an operating frequency of the compressor at the beginning of a heat accumulating operation in which the heating medium heated by the heat exchange means is accumulated in the heat storage tank. The initial operation includes a first operation that maintains the operating frequency at a first frequency and, after the first operation, a second operation that maintains the operating frequency at a second frequency higher than the first frequency.

摘要： A settings data storage stores unique serial numbers and information regarding a plurality of patterns for alternately switching between normal operation for operating at high capacity and suppressed operation for operating at low capacity each unit time. A pattern specifier determines information for a pattern set in accordance with even and odd serial numbers. A water-heating heat amount determiner determines a heat amount necessary for water heating. A water heating scheduler establishes a water heating plan based on information regarding the pattern determined by the pattern determiner and the water-heating heat amount as determined by the water-heating heat amount determiner. A water heating controller alternately switches between normal operating and suppressed operation to heat water in accordance with the water heating plan established by the water heating scheduler.
