What Is Heat Output in Commercial Washers and Why It Matters?

Heat output in commercial washers means the amount of heat energy generated during washing cycles. The high-temperature cycles that are necessary for washing and disinfecting clothes produce this heat as a byproduct.

Heat output has great importance in laundry operations. This high heat level in laundry operations helps in complete cleaning and sanitation. They also help break down stains,  kill bacteria, and dissolve detergents efficiently.

Appropriate heat output can expedite drying and laundry processes and increase throughput in operations with high demand. Furthermore, effective machinery reduces unnecessary energy use. This helps to strike a balance between the requirement for high temperatures and operational expenses.

The heat output impacts the overall facility. An excessive amount of heat output can cause laundry rooms’ ambient temperatures to rise.

This puts more strain on the building’s HVAC system and raises the facility’s overall energy consumption. Effective heat control minimizes machine wear and saves energy expenses. It also helps lower maintenance costs related to temperature extremes.

How to Measure and Calculate Heat Output in Commercial Washers

Firstly, to measure and calculate the heat output in commercial washers, you need to have a few tools. A thermometer will be helpful to measure water temperature. A Flow Meter is used to measure water volume and a stopwatch will track washer run time.

  • The temperature of the water would be measured in (°C or °F).
  • Calculate the volume of water used per cycle (in liters or gallons).
  • Specific Heat Capacity of Water ( C). This constant is 4.186 J/g°C or 1 BTU/lb°F.
  • Record the duration of each wash cycle (in seconds or hours).

To calculate the heat output, use this formula:

Q=V×C×ΔT

Where:

Q = heat output (Joules or BTUs)

V = water volume (liters or gallons)

C = specific heat capacity of water

ΔT = temperature difference (°C or °F)

To measure the temperature difference, use this formula: 

ΔT = Exit Temperature – Inlet Temperature

The Impact of Washer Heat Output on HVAC Systems

There is a significant impact of water heat output on the performance of your HVAC system. Washers generate a substantial amount of heat during operation, especially in facilities handling large volumes of laundry.

This heat can cause a cooling load on your HVAC system. This requires more cooling capacity to maintain the optimal indoor temperature. 

Higher heat output causes higher energy consumption. It requires more energy-efficient designs for your HVAC system that can manage the heat load without excessive operational costs.

For the heat generated by washers to be dispersed, proper ventilation is essential. The configuration of your HVAC systems needs to prioritize the removal of hot and humid air to provide comfort. This prevents excessive humidity that can affect facility equipment.

Comparing Energy Efficiency Across Commercial Washer Models

The amount of heat output and energy efficiency of commercial washer models differ. To achieve optimal performance in various washing operations, it is necessary to compare these factors. 

 

High-efficiency front-load Washers reduce heat output compared to conventional versions because of their shorter cycles and less water usage. They are extremely efficient, consuming between 50-60 % less power and water than top-load washers. 

 

Another commercial washer model is a top-load washer. Heat output in top load washers can range from moderate to high depending on the water level and cycle length. These washers frequently produce more heat since they need to heat the water more. They are generally less efficient than front-load types. They use more energy and water , especially at higher heat settings and longer cycles. 

 

Another mode that has high heat output is tunnel washers.  In tunnel washers heat output is high due to their large-scale facilities that handle hundreds of pounds of laundry every day. This is one of the most efficient types of commercial washers.

 These washers save energy by processing numerous loads at the same time and lowering the need for hot water.

Practical Tips for Reducing Heat Output in Commercial Laundry Facilities

To enhance operational efficiency, it is important to reduce heat output in commercial laundry facilities.

  • Upgrade to high-efficiency models. Modern high-efficiency laundry machines consume less water and energy than previous ones.
  • Choose washers with built-in heat recovery technologies that capture and reuse heat. It will help reduce the need for further heating and cooling.
  • Install high-performance ventilation systems to effectively disperse heat. Proper ventilation reduces heat accumulation and keeps the facility cool.
  • Install localized exhaust systems near washers to remove hot air at the source and reduce its spread across the facility
  • Use Cold-water detergents. Cold-water detergents function effectively at lower temperatures and reduce heat generated during washing.
  • Insulating hot water pipes reduces heat loss during water transmission. It helps manage temperature control within the facility and reduces heat output from washers.
  • Regular maintenance of laundry equipment helps to prevent substantial efficiency losses. Clogged filters, worn-out belts, and inefficient motors cause machines to work harder.
  • Schedule frequent check-ups to extend the life of your machines and keep them functioning at top performance.

Case Studies: Real-World Solutions to Managing Heat in Commercial Laundries

One real-world example is from University Campus Laundry, Boston, MA. During the summer of 2017, every laundry room in the Housing portfolio was prepared for the replacement of more than 300 washing machines on campus.

This facility was facing high heat output from laundry operations during peak usage periods. Due to the high heat levels, their HVAC system got overloaded which caused them high operational costs. So, The university upgraded the facility with energy-efficient washers and installed a sophisticated HVAC system.

The HVAC system automatically changed cooling based on the washers’ real-time heat production. It helped the facility in managing proper temperature regulation. Overall, the new washers are estimated to save more than one million gallons of water per year.

Another real-world example is from the healthcare sector. In  Regional Hospital laundry, Chicago, IL. The facility faced high humidity and heat levels from washer and dryer operations that caused discomfort for staff.

It also raised the maintenance costs for their HVAC systems. The facility improved its ventilation system by installing high-capacity exhaust fans and ductwork to collect hot air straight from the washing room. They also changed the airflow structure to improve air circulation and ensured that hot air was blown out efficiently.

Factors Affecting Heat Gain from Commercial Washers and Dryers

Heat gain from commercial washers and dryers is affected by a number of factors, including equipment type, water temperature, and ventilation efficiency.

Equipment Types

 It affects the heat gain from commercial washers and dryers.  Larger industrial machines, such as washer-extractors and tunnel washers, generate a lot of heat due to their size and continuous operation.

Newer models with heat recovery systems generate less heat. Top-load washers use more water and have longer cycles that produce more heat.  But, front-load washers are more efficient, use less water, and create less heat. 

Gas dryers generate greater heat due to the combustion process. But, electric dryers provide better-controlled heat levels while still contributing to heat gain. In contrast, heat pump dryers recycle heat that lowers the facility’s overall heat output.

Water Temperature

Heat gain is also influenced by water temperature. Higher water temperatures cause greater heat gain. Washers with frequent hot water cycles emit more heat into the surrounding environment.  In facilities where water is preheated centrally, hot water pipes near the laundry area can also produce high heat levels.

Ventilation Efficiency

Efficient venting systems help to remove heat and humidity from the indoor environment. Proper exhaust ventilation helps reduce heat gain. Poorly built or congested ventilation systems can recirculate hot air around the property. It raises indoor temperatures.
