HEAT PUMP SYSTEM - A simplified explanation of the abstract

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

Simplified Explanation: The patent application describes a heat pump system that efficiently heats ventilation air using 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 to transfer heat.
• The heating unit heats ventilation air by releasing heat from the refrigerant in the condenser.
• The low-temperature side heat medium circuit circulates a low-temperature side heat medium to absorb heat in the evaporator.
• The control unit adjusts the temperature of the low-temperature side heat medium to achieve a predetermined heat transfer target by controlling the compressor's rotation speed and the heat source device's operation.

Key Features and Innovation:

• Efficient heating of ventilation air using a heat pump system.
• Control unit adjusts heat transfer to meet predetermined target values.
• Integration of heating unit, low-temperature side heat medium circuit, and control unit for optimal performance.

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.
