Heating and cooling system

HEATING AND COOLING with a HYBRID SYSTEM


The solution to providing the highest and most up-to-date level of air conditioning in our buildings is realized with the employment of hybrid heating and cooling systems manufactured by "IMMERGAS". These hybrid systems are the ideal solu-tion for new homes with integrated heating, cooling and domestic hot water sys-tems and are in line with the European standards and regulations regarding the use of renewable energy sources.

Hybrid systems are characterized by a state-of-the-art technology which combines a highly efficient gas boiler with a heat pump unit for renewable energy. Each kilo-watt of electricity, used by a hybrid system, generates 3 to 4 times more rene-wable heat from the outside air thus generating exceptional energy efficiency: in the heating and domestic hot water production mode they can be up to 35% more efficient than the standard gas boilers and they also help save money on energy bills minimizing – at the same time - the total volume of pollutants into the atmosphere. The available automatic mode selection (ensured by the device`s software) of the more favorable source of heat during the winter periods makes these systems even more economical than the combination of a gas boiler and single unit air conditioner for each room in the residence.

The hybrid system consists of a combined gas boiler with an integrated freon/water heat exchanger installed in the room while the system`s heat pump is mounted outside - on the facade or on the roof of the building. Unlike the generally practiced solutions leading out the exhaust gases from the gas boilers, in our con-structions we have closely followed the respective European requirements. The installed collective coaxial fume systems guarantee the removal of the combus-tion products above the roof of the building with a simultaneous suction of guaran-teed clean air for the appliances thus prolonging their service life and making the service maintenance operations easier.

The provided indoor smart control system allows the users to remotely select the desired temperature and/or operation mode/values via a mobile application.

In the “Algara Luxor” and the “Espor Center” buildings, the “Immergas” hybrid solu-tions have been represented by:

The Magis Combo hybrid system - for the residential sector
A hybrid system combining an Audax Top ErP thermal pump with a Victrix Pro ErP or Victrix kW TT condenser gas boiler for the offices
The installation in both buildings is completed with a radiant water floor heating system and high-wall Hydro convector cooling units from “Immergas”.

For all hybrid systems the manufacturer has exclusively provided a 60 months wa-rranty period for all components of the appliances and the other air conditioning devices.

A DESCRIPTION OF MAGIS COMBO:

Magis Combo is a hybrid system which generates central heating, cools and he-ats domestic hot water with the integrated condensing unit, designed to cover even the highest load requirements. The outdoor heat pump module is offered in three single-phase versions: 5, 8 and 10 kW. The indoor unit is equipped with a condensing heat generator (27 kW for DHW heating and 24 kW for central hea-ting) and a built-in hydraulic module which controls the energy exchange between the cooling system and the water circuit.

Compared to the condensing boilers, Magis Combo is compact and offers signi-ficant energy savings due to its high energy efficiency. Especially suitable for new and renovated homes, built according to the highest insulation criteria Magis Combo is an excellent solution for replacing old gas boilers with medium and high temperature systems. Its heating temperature can reach 80° C.

What`s unique about the Magis Combo?

Unlike other hybrid systems which operate in parallel, Magis Combo runs sequen-tially. In the event that in the heating mode the heat pump in the hybrid system is running and the coolant temperature does not reach the desired value for the time period set by the thermostat the latter switches off and is replaced by the gas module which reaches the set temperature thus ensuring maximum heating effi-ciency.

Basic features of the indoor unit:

R410A /water heat exchanger with 48 plates/
Stainless steel gas condensing module
A 10 liter expansion tank
Flostat, which activates the heat pump only at a sufficient water flow rate

DESCRIPTION OF THE AUDAX TOP ErP:

The air-to-water thermal pumps from “Immergas” use air as a renewable energy source. The inverter's intelligent functions and the specific air distribution provide constant comfort indoors without noticeable temperature changes irrespective of whether it is hot or cold outside.

The Audax Top ErP is a single body air-to-water heat pump, suitable for all system solutions and it can be combined with a gas boiler or with a separate volume boiler for domestic hot water production. Thanks to the inverter technology low electricity consumption and high heat and cold productivity are combined, especially during the transitional seasons, when the heating requirements of the building are low and no operation of the heat pump at nominal power is required. The adopted special technical solutions have greatly reduced the noise levels during operation.

 The product range includes:

- 4 single-phase versions for residential applications - 6, 8, 12 and 16;

- 3 triple phase versions suitable for public and office buildings - 16, 18 and 21.

Optimal operation of systems with fan convectors and radiant floor hea-ting/cooling systems with a maximum supply line temperature of up to 60℃. Audax Top ErP can function in low or medium temperature systems. For cooling, heat pumps are the ideal solution when combined with fan convectors and an air dryers.
