HEAT PUMP SYSTEM - A simplified explanation of the abstract

This abstract first appeared for US patent application 18745661 titled 'HEAT PUMP SYSTEM

The abstract describes a heat pump system that includes a heat pump cycle, a heating unit, a low-temperature side heat medium circuit, and a control unit. The heat pump cycle consists of a compressor, a condenser, and an evaporator. The heating unit heats ventilation air using heat released from the refrigerant in the condenser. The low-temperature side heat medium circuit circulates a low-temperature side heat medium, allowing the refrigerant in the evaporator to absorb heat from the low-temperature side heat medium. The control unit adjusts the amount of heat transfer in the heating unit to achieve a predetermined target value by controlling the rotation speed of the compressor and the operation of the heat source device and heat amount adjustment unit.

• The system utilizes a heat pump cycle to transfer heat efficiently.
• The heating unit heats ventilation air using heat from the refrigerant.
• The low-temperature side heat medium circuit helps in absorbing heat from the low-temperature side heat medium.
• The control unit adjusts the heat transfer to achieve a target value by controlling the compressor's rotation speed and the heat source device's operation.
• The system aims to optimize heating efficiency and control heat transfer effectively.

Original Abstract Submitted

A heat pump system includes a heat pump cycle, a heating unit, a low-temperature side heat medium circuit, and a control unit. The heat pump cycle includes a compressor, a condenser, and an evaporator. The heating unit heats ventilation air with heat released form refrigerant in the condenser. The low-temperature side heat medium circuit circulates a low-temperature side heat medium such that the refrigerant in the evaporator absorbs heat of the low-temperature side heat medium, and includes a heat source device and a heat amount adjustment unit. The control unit causes an amount of heat transfer in the heating unit for heating the ventilation air to approach a predetermined target value via adjustment in temperature of the low-temperature side heat medium by controlling a rotation speed of the compressor and an operation of at least one of the heat source device and the heat amount adjustment unit.
