Thermia Mega in Brief 2
What’s NEW?
New features in Thermia Mega:
+ Refrigerant: R410A
+ Thermia VHZ compressor (dedicated for R410A)
+ Electronic expansion valve
+ Circulation pumps
+ Asymmetric condenser
Current technologies used in our light commercial heat pumps:
+ Hot gas exchanger
+ Online – remote control
The ambient temperature changes during the day, and consequently so does the heat load
There are seasonal variations in ambient temperatures
Heating system needs to adjust heating capacity to match the load
Why part load operation & modulation?
Why Modulation Technology? 3
HVAC systems are designed for peak conditions
Peak conditions are only a small percent of the operations
Thermia inverter scroll solutions are designed to provide only the heating or cooling needed when needed.
No More, no Less.

What difference can modulation make?
Without Modulation technology
• Supply air temperature will be cooler than required due to excess capacity.
• Zone set point is maintained by on-off cycling.
With Modulation technology
• Air temperature supply is closer to the set point.
• The zone temperature is kept close to the set point at all times by the load-matching operation.
Near zero in-rush current with variable speed technology

Customer Benefits – Reduced demand on Power Grid
Customer Benefits of Modulation Technology
Compressor capacity always matches heating or cooling demand – area between grey and red line is customer savings!
Efficiency boost in part load operation : compressor runs slower
Less capacity at slower speeds : unit becomes effectively over-sized
No on/off pressure cycling and transient losses
Customer Benefits - Inverter compressor
1. Inverter scroll technology: load matching principle
2. Two models dedicated to different Pressure Ratios Systems
3. High Efficiency Permanent Magnet Motor Benefits:
Annual Energy Savings with inverter scroll:
10-15% vs tandems 20-25% vs digital hybrid tandem 30%+ vs fixed-speed compressor or
digital technology
Unmatched energy efficiency thanks to a smart design:

called the de-superheater located between
compressor and condenser
• Gas temperature in the de-superheated is
above 100°C and supports hot tap water
production
• Calculated simulation of the system with and

Reduce energy consumption in existing buildings considerable by using exhaust air as energy source for heat pump solution.
Potential: Ten thousands of existing multifamily homes are today simply “blowing the exhaust air from kitchens and bathroom out in the blue”.
One example is the Swedish “Miljonprogrammet” where one million homes were built between 1965-1974. Over 300 000 flats are still not renovated and could in many cases be targeted with this application.
Business Case - Apartments 9
43│
Making use of the energy:
Install a heat pump solution and use the exhaust air as energy source - install a heat pump in the basement and an air/brine heat exchanger on the roof and connect these with two brine water pipes
Connecting the heat pump to the existing heating system:
The heat pump will produce both domestic hot water as well as heating for the hydronic heating system. An exhaust air heat pump will normally cover ~50% of the energy demand with suggested solution
Connecting to the current system - the heat pump will be connected to the existing heating system (District heating or gas/oil), The heat pump controller will communicate with the existing heating system

Mega heat pump with variable speed compressor heat pumps are superior in this application due to:
Works with variable ventilation flow and extracts maximum amount of energy from the exhaust air second by second, day after day = highest possible savings
Flexible power output reacts to demands in the hot water and heating system, not the other way around! = Lower running cost and simpler installation due to less need for volume tanks
“Energy Source Control” secures that the unit will automatically adapt to any desired temperature in the exhaust air = Fail safe selection, one unit will fit all applications.

Huge savings and very short pay back Example with a block of flats with 10.000 m2
Current yearly energy consumption:
• Heating: 2.100.000 kWh
• Domestic hot water: 700.000 kWh
• Total: 2.800.000 kWh
Utilising the energy from exhaust air with a heat pump
in combination with existing district energy:
• Heating: 1.500.000 kWh
• Domestic hot water: 200.000 kWh
• Total: 1.700.000 kWh
Realized savings vs. existing solution:
1,1 mio kWh ~ 730.000 SEK/year
Estimated cost to establish solution: 1,7 mSEK
Simple pay-back time: 2-3 years
