2.Applications

Any hot water application up to 70 deg C

Typical applications

  1. Pre-treatment at paint shops
  2. Phosphating
  3. De-greasing
  4. Oil separation
  5. Plating
  6. Cathode Electro Deposition
  7. Curing
  8. Pickling
  9. Component washing

As an added benefit, heat pumps can double down on your energy efficiency if there is a concurrent need for process cooling. This kind of application is prevalent in the food processing industries such as breweries, dairy etc.

3.What is heat pump?

A heat pump is a system, which moves heat from a cold zone to a hot zone. An example would be the refrigerator commonly used in our homes. Traditionally heat pumps are used to maintain “coolness” in conditioned spaces. However, in industrial applications we are interested in using the heat generated in the hot zone. Here is a comparison between the two systems:

Description Chiller Heat Pump
Process Refrigeration Cycle Refrigeration Cycle
Application Used for Process Cooling Used for Process Heating
Utilization Point Evaporator Condenser
Condensing temperature 30 to 35 deg C 80 to 90 deg C
Evaporating temperature 7 to 12 deg C 15 to 20 deg C

 

How does heat pump deliver lower energy cost

Heat pumps operate on the principle of vapour compression refrigeration system. In takes in energy from any ambient resource such as air, water or underground, and increases the quality of heat by adding extra energy. This extra energy is by using electricity.
What is the temperature attainable? Most heat pumps available in the market commercially provide you with hot water temperatures up to 75 C. Aspiration Energy’s high temperature systems can provide temperatures even up to 90 C. This is attainable through improvements in compressor operation and choice of refrigerants. .

How much can I save?

An average of 40,000 per month

How does it save Rs. 40000 per month?

This matrix should give you an idea of the yearly savings (rupees) possible at different loads (kW) and percentage utilization (hours)

Average Load (KW) 18 19 20 21 22 23 24 25
% Utilization (hours)
50% 22,680 23,940 25,200 26,460 27,720 28,980 30,240 31,500
60% 27,216 28,728 30,240 31,752 33,264 34,776 36,288 37,800
70% 31,752 33,516 35,280 37,044 38,808 40,572 42,336 44,100
80% 36,288 38,304 40,320 42,336 44,352 46,368 48,384 50,400
90% 40,824 43,092 45,360 47,628 49,896 52,164 54,432 56,700
100% 45,360 47,880 50,440 52,920 55,440 57,960 60,480 63,000

How is the above table calculated?

The energy saved is calculated based on the average load at percentage utilization of 24 hours.
Energy saved = Load of the heat pump x No. of hours x Cost of Electricity x Savings from Heat Pump x No. of working days in a month

For example
At 18 kW load and on running 50 percent of the day, Savings of a heat pump = 18 * (24*0.5) * 7 * 50 % * 30 = 22680 rupees/ month

Note: Heat pump is conservatively assumed to save 50 % of existing energy cost
The heat pump is assumed to run 30 days in a month
Electricity cost is assumed at 7 rupees/kW

4.What are thermal systems?

  • Boilers: steam, hotwater, thermic fluid generators
  • Direct fired hot air generators
  • Furnaces
  • Resistance/induction heaters

5.How do we measure?

Using two temperature sensors and a flow meter . The heat pump outlet and the inlet temperatures are measured and the flow rate.  

How is the heat delivered calculated?

By simple calculation, Heat delivered = (T2 – T1) * Mass Flow Rate * Specific Heat of Water
