Waste Heat Recuperator for Ammonia System

Waste Heat Recuperator for Ammonia System

Waste heat recovery for ammonia systems is a device used to recover the waste heat generated in ammonia refrigeration systems. Ammonia refrigeration systems are commonly used in refrigeration and air conditioning systems in industrial and commercial sectors. In an ammonia refrigeration system, ammonia is compressed into a high-pressure gas, which is then cooled and condensed into a liquid through a condenser, releasing a large amount of heat.

Waste heat recoverers for ammonia systems are designed to utilise this generated heat and reuse it to heat other fluids such as water or air, thereby improving energy efficiency. A typical waste heat recovery unit usually consists of a heat exchanger and a heat exchanger, which transfers and reuses energy by exchanging heat between the hot ammonia gas and the medium that needs to be heated.

This waste heat recovery technology not only helps to save energy and reduce energy costs, but also helps to reduce the negative impact on the environment as it reduces the need for other energy sources, reduces carbon emissions, etc.

The design and selection of waste heat recoverers for ammonia systems depends on the specific application scenario, system size and requirements, and usually requires consideration of factors such as medium temperature, flow rate, pressure and heat transfer efficiency.

The structure of waste heat recovery units for ammonia systems usually depends on their specific application scenarios and design requirements, but in general they consist of the following main parts:

Heat exchanger or heat exchanger: this is the key component for heat exchange between the ammonia gas and the medium to be heated. The heat exchanger can be constructed in different configurations such as plate heat exchanger, tube heat exchanger, shell and tube heat exchanger, etc. for efficient heat transfer.

Ammonia pipework: this is the pipework that directs the high temperature ammonia gas into the heat exchanger. The piping is usually made of high-temperature and corrosion-resistant materials to ensure its stable operation under high temperature and pressure.

Heating medium piping: This is the piping system that guides the medium to be heated into the heat exchanger. Depending on the specific application requirements, the heating medium can be water, air or other fluids. The material and design of the pipework also needs to take into account the characteristics of the medium and the operating conditions.

Support structure and shell: In order to support and fix the heat exchanger and its pipework, there is usually a support structure and shell. The casing also serves to protect the internal components of the heat exchanger and provides thermal and safety insulation.

Control system: In order to realise the control and monitoring of the waste heat recovery process, it is usually necessary to equip the corresponding control system, including monitoring and regulating devices for temperature, pressure, flow and other parameters.
