HEAT PUMP SYSTEM - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240337420 titled 'HEAT PUMP SYSTEM

The patent application 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 temperature of the low-temperature side heat medium by controlling the rotation speed of the compressor and the operation of the heat source device and heat amount adjustment unit to achieve a predetermined target value for heating the ventilation air.

Potential Applications: - HVAC systems for residential and commercial buildings - Industrial heating and cooling processes - Energy-efficient heating and cooling solutions for various applications

Problems Solved: - Efficient heating and cooling of ventilation air - Precise control of heat transfer processes - Energy savings through optimized operation

Benefits: - Improved energy efficiency - Enhanced control over heating and cooling processes - Cost savings on heating and cooling operations

Commercial Applications: Title: Energy-Efficient HVAC Systems for Sustainable Buildings This technology can be utilized in the development of energy-efficient HVAC systems for sustainable buildings, offering cost-effective and environmentally friendly heating and cooling solutions.

Questions about Heat Pump System: 1. How does the control unit adjust the temperature of the low-temperature side heat medium? The control unit adjusts the temperature by controlling the rotation speed of the compressor and the operation of the heat source device and heat amount adjustment unit.

2. What are the key components of the heat pump cycle in this system? The key components of the heat pump cycle include a compressor, a condenser, and an evaporator.

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.
