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.

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 costs ?

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 Cleantech Ventures’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)

% Utilization/day	100%	90%	80%	70%	60%	50%
Average Load (kW)
25	63,000	56,700	50,400	44,100	37,800	31,500

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

What are thermal systems?

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

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

FAQs

Can I use it for a single shift operation in my plant?

Yes, it would be technically feasible without a doubt, but the savings, in economical terms would not be substantial – around Rs 30,000 per month for even for full load conditions

Do you get cold air from the heat pump?

Yes, cold air can be a free output from heat pumps in the evaporator side. However they cannot be used for Air conditioning processes as the temperature delivered will be in the range of 15 to 20°C

Is a CAPEX Model available for buying the same heat pump?

Yes, Heat Pumps that are available in Capital Investment Models with accelerated depreciation benefits
