1. Composition of the heat pump system

The heat pump system is mainly composed of a compressor, an evaporator, a condenser and a throttle valve. The compressor is the core component of the heat pump system. Its function is to compress the low-temperature and low-pressure refrigerant into a high-temperature and high-pressure gas, and then transfer heat through the evaporator and condenser.

2. Workflow of the heat pump system

Evaporator: The refrigeration process of the heat pump system starts at the evaporator, where the refrigerant evaporates and absorbs heat from the surrounding air, water, or ground.

Compressor: After evaporation, the refrigerant becomes a low-temperature and low-pressure gas, which is then compressed into a high-temperature and high-pressure gas by the compressor.

Condenser: The high-temperature and high-pressure gas is cooled by the condenser and becomes a high-pressure and low-temperature liquid.

Throttle valve: The liquid refrigerant then passes through a throttle valve, which reduces its pressure and temperature, preparing it to absorb heat again. After this, the refrigerant returns to the evaporator, and the cycle starts anew.

3. Common problems

The heat pump system is difficult to repair, and users who are not familiar with the technology need to ask professional technicians to come to the door for repair.

The higher installation cost is due to advanced components and installation requirements designed to maximize efficiency. Once installed, the system’s high efficiency significantly lowers monthly energy bills. Unlike traditional systems that rely on burning fuel or electric resistance, heat pumps transfer existing heat, making them 2-4 times more efficient. This translates to lower energy usage for the same heating or cooling output, resulting in long-term cost savings.

The heat pump system will generate some noise during operation, but the noise can be reduced through reasonable design, sound insulation and speed reduction measures.

4. Summary

The heat pump system is an efficient and energy-saving heating and cooling equipment, which is mainly composed of a compressor, an evaporator, a condenser and a throttle valve. During operation, the heat pump system transfers heat through the change of the refrigerant. Although there are some problems with the heat pump system, we can avoid these problems through reasonable maintenance and use, and it has a good performance in energy saving and environmental protection.
