Introduction
In recent years, there has been a growing interest in using gas-fired absorption heat pumps for industrial heating applications due to their high efficiency and low environmental impact. However, these systems require a lot of energy to operate, which makes them expensive to run. To address this issue, many manufacturers have started to incorporate heat recovery systems into their gas-fired absorption heat pumps. In this article, we will discuss the most common types of heat recovery systems used in gas-fired absorption heat pumps for industrial heating applications.
What is a Gas-Fired Absorption Heat Pump?
Before diving into the different types of heat recovery systems used in gas-fired absorption heat pumps, let’s first understand what a gas-fired absorption heat pump is. A gas-fired absorption heat pump is a type of heating and cooling system that uses a refrigerant and an absorbent to transfer heat from one place to another. These systems use natural gas as a fuel source to power the absorption process, which allows them to be highly efficient and environmentally friendly.
Types of Heat Recovery Systems
There are several different types of heat recovery systems that can be used in gas-fired absorption heat pumps for industrial heating applications. Let’s take a closer look at some of the most common ones.
Flue Gas Heat Recovery
Flue gas heat recovery is one of the most common types of heat recovery systems used in gas-fired absorption heat pumps. This system works by recovering the heat that is typically lost through the exhaust gases of the gas-fired absorption heat pump. The recovered heat can then be used to preheat the incoming air or water, which can help to reduce the amount of energy required to heat the space or water.
Condensate Heat Recovery
Condensate heat recovery is another common type of heat recovery system used in gas-fired absorption heat pumps. This system works by recovering the heat that is typically lost through the condensate that is produced during the heating process. The recovered heat can then be used to preheat the incoming air or water, which can help to reduce the amount of energy required to heat the space or water.
Waste Heat Recovery
Waste heat recovery is a type of heat recovery system that works by recovering the heat that is generated by other industrial processes. This system can be used in conjunction with a gas-fired absorption heat pump to recover the waste heat and use it to preheat the incoming air or water. This can help to reduce the amount of energy required to heat the space or water, which can result in significant energy savings.
Solar Thermal Heat Recovery
Solar thermal heat recovery is a type of heat recovery system that uses solar energy to preheat the incoming air or water. This system works by using solar collectors to absorb the energy from the sun and transfer it to the air or water. The preheated air or water is then sent to the gas-fired absorption heat pump, which can help to reduce the amount of energy required to heat the space or water.
Conclusion
Gas-fired absorption heat pumps are an excellent choice for industrial heating applications due to their high efficiency and low environmental impact. However, they can be expensive to run due to the amount of energy required to operate them. By incorporating heat recovery systems into these systems, manufacturers can significantly reduce the amount of energy required to heat the space or water. Flue gas heat recovery, condensate heat recovery, waste heat recovery, and solar thermal heat recovery are some of the most common types of heat recovery systems used in gas-fired absorption heat pumps.
