What Are the Different Kinds of Heat Pumps Used In Industrial Settings?

A technological innovation, heat pumps are quite similar to refrigeration cycles, with the distinct difference of providing heat with an advanced system with the capability to produce both heat and cold. The basic process involved is that the heat pumps transfer heat by extracting low-grade heat from a source and then upgrading it to produce heat at high pressure.

One of the major advantages of using heat pumps is the significant possibility of saving energy as they recover and utilize waste heat, raising its levels to make it useful. This is why many industries around the world are switching to investing in heat pumps for their manufacturing and production plants and factories. Heat pump companies in Ahmedabad manufacture pumps for two primary areas of application: residential and industrial.

The different kinds of heat pumps used in various industries

1. Rotation pumps: Since the past few years, due to the increasing limitation on fossil fuel, the chemical industry has shifted to using Rotation pumps made by the heat pump companies in Ahmedabad for their ability to concentrate salt solutions and help in the treatment of effluent. Rotation pumps efficiently surpass the ability of conventional heat pumps with their technology of generating both heat and cold, which are essential for the chemical industry's hot and cold water requirements in their production processes.
2. Positive displacement pumps: Heat pumps are a major cost saver for the food and beverage industry by replacing the use of gas. An environmentally friendly resource, both positive displacement and rotodynamic heat pumps help in brewing beer in the beverage industry and with the concentration of liquid products in both the beverage and dairy industries.
3. Compression pumps: An industrial heat pump in India can efficiently help with the reduction of carbon emissions and make sustainability achievable. Production of paper emits high levels of carbon dioxide, leading to carbon emissions, which the compression heat pump cuts down by concentrating the emission during water heating, black liquor, flash-steam recovery, and product drying processes by transferring the heat from the thermal energy via a refrigerant liquid.
4. Solar-assisted rotation heat pump: As we transfer our energy resources from fossil fuels to sustainable, environmentally friendly solar energy, the automotive and mechanical industries in particular are adopting solar-assisted heat pumps, or SAHP. The demand for high thermal energy in this industry is excessive, which is not only very expensive but also has adverse effects on the environment. SAHPs improve the efficiency of energy, which brings down the cost and excessive consumption of energy. Rotation Heat pumps are used for various processes in the paint shop, like paint drying and moulding in the automotive industry and drying processes at various stages in the mechanical industry.
5. Industrial heat pumps: Electrified industrial heat pumps are the common denominator between many industries in India. They are extensively used in the textile industry for multiple processes like wash water heating, concentration of dilute dope systems, and space heating. Due to the high consumption and cost of electricity, the textile industry is shifting to solar-assisted industrial heat pumps.

These pumps are also used in the metal industry for their efficiency and relatively economical usage for varied purposes entailing degreasing, chromating, electroplating, drying, phosphating, pickling, and purging.

The wood and forest industries are highly dependent on heat pumps for various stages of production, from cooking to pickling, drying, gluing, staining, pressing, and steaming.

6. Industrial heat pumps for the pharmaceutical industry: The pharmaceutical industry uses four types of heat pumps:

• The centrifugal pump is the most commonly used pump in the pharma industry for its high efficiency and simple design that makes it easy to operate, cost-effective, and reliable.
• Chemical pumps are second only to centrifugal pumps and are capable of handling corrosive and aggressive liquids and transferring all types of liquids, including water.
• Polypropylene pumps are high-performance pumps used to transfer oils, chemicals, slurry, and descaling liquids, among many other liquids. Their compact design makes them low-maintenance and easy to operate.
• Air-cooled pumps, or thermic fluid pumps, are heavy-duty heat pumps used to pump chemicals in high-temperature applications. Easy to maintain, these pumps have a heat resistant mechanical seal with centreline support casting, giving them a longer shelf life.

Apart from the above areas of application, heat pump companies in Ahmedabad manufacture pumps for drinking water processing plants, steam stripping plants, electroplating, and many other industrial purposes.
