How Smart Laundries Profit from Waste Heat

Laundry plants are big heat consumers. The expenditure on steam and gas usually accounts for 20% to 30% of the total cost of a laundry. If the thermal energy can be fully utilized, it can save a considerable amount of expenses for laundry plants. There are several machines in laundry plants that need to use heat: the tunnel washer, tumble dryer, and ironer. Tumble dryers and irons not only consume heat themselves but also emit a portion of it. Currently, some laundry factories are designed to save costs by discharging heat, making the factory environment more comfortable. Let’s take a look together.

Case 1

In terms of the tumble dryer, this laundry plant has done a good job in insulating the dryer, which can reduce heat loss and energy consumption.

● Tumble Dryer

The CLM dryer has insulation layers added to the outer cylinder, panel, and other parts, so there is no need to do separate insulation. After the insulation work is done, the exhaust pipe of the dryer is connected to a dedicated room for heat recovery to heat the water tank in the room. Then this part of the hot water can continue to be used for washing work.

● Ironer

For the ironers in the laundry factory, CLM always installs a cover on their top. The purpose of doing this is to discharge the heat emitted outside the factory building, so as to maintain a comfortable environment inside the factory building.

Many laundry factories directly discharge this part of the heat into the outdoor environment. However, this laundry factory also introduces this part of the heat through pipes into a dedicated room for heat recovery to heat the water in the water tank and use the hot water for washing. The hot water of this laundry factory is not only available for its own washing. The extra hot water can be supplied to places that require a large amount of hot water, such as bath centers, which can bring an additional income to the laundry.

Case 2

There is another laundry factory that has added a heat energy recovery converter at the exhaust pipe through the tumble dryer. By virtue of the circulation of water flow, it can absorb the heat energy of the exhaust pipe and heat the normal temperature water at the same time. Heated water can be used for washing linen, and it can also reduce heat emissions. Making full use of this preheating part can reduce the energy consumption of the laundry.
