Can the air conditioning system be coupled with the photovoltaic installation?

Yes. If the heat pump runs preferentially when there is sun, the PV electricity is used directly instead of being sourced expensively from the grid. The building then acts as a thermal storage — pre-warmed or pre-cooled during low-cost hours.

What is a digital twin of a hotel's air conditioning technology?

A live image from actual sensors (flow temperature, outdoor temperature, flow rate, power, COP), which checks against learned target ranges, detects issues like COP drop early, and explains in plain language what needs to be done.

Air conditioning, heating & ventilation in the hotel (HVAC) — explained with full transparency

Q: What does HVAC mean in the hotel?

HVAC stands for heating, ventilation and air conditioning (Heating, Ventilation, Air Conditioning). In the hotel, this includes the heat pumps or boilers, the room air technology (RLT) with heat recovery as well as cooling — together the largest energy block of the building.

Q: Why are climate control and ventilation the largest consumers of energy in the hotel?

Climate, heating, and ventilation run around the clock for all rooms, corridors, meeting areas, and wellness zones. As a rough guide, often around one-third of a hotel's energy consumption is attributed to HVAC — varying greatly depending on the building and climate.

Q: What is the COP of a heat pump?

The COP (Coefficient of Performance) indicates how much heat a heat pump delivers per kilowatt-hour of electricity used. A COP of 5 means five kilowatt-hours of heat from one kilowatt-hour of electricity — approximately 80 percent less electricity consumption than an electric direct heater. Realistically, the COP range lies between 4 and 7 depending on the temperature.

Q: What does heat recovery in ventilation provide?

Heat recovery (WRG) transfers heat from the exhaust air to the fresh supply air. Modern systems achieve high recovery rates — around 63 percent at a reference system — so that significantly less supplementary heating or cooling is required.

Q: What does an AI detect in climate technology that building management systems do not see?

Building management systems only report when a limit is exceeded. The AI detects a slowly decreasing COP (icing, refrigerant shortage, contamination), unnecessary simultaneity of heating and cooling, as well as load peaks from the interaction of outdoor temperature, flow temperature, flow rate, and electrical power.

Q: How does AI reduce peak loads in air conditioning technology?

It shifts pre-cooling and pre-heating to times with a PV surplus or cheap electricity and prevents heat pumps, ventilation, and cooling from ramping up simultaneously. Thus, the highest 15-minute power output, which determines the power price, decreases.

What is the COP of a heat pump?

The COP states how much heat a heat pump delivers per kilowatt-hour of electricity used.COP 5= five kWh of heat from one kWh of electricity — approximately80 % less electricitythan an electric direct heater. Realistically, the range lies between depending on temperature 4 et 7 .

What does heat recovery in ventilation provide?

La Heat recovery (WRG)transfers heat from the exhaust air to the fresh supply air. Modern systems achieve high recovery rates — at a reference system around63 %— so that much less additional heating or cooling is necessary.

What does an AI detect that building management doesn't see?

Building management only signals in case of exceeding the limit. The AI detects adecreasing COP(icing, refrigerant, contamination), unnecessary simultaneity of heating and cooling as well as load peaks from the interaction of outdoor temperature, flow temperature, flow rate, and power.

How does AI reduce peak loads in air conditioning technology?

It shifts pre-cooling and pre-warming to times with a PV surplus or cheap electricity and prevents heat pumps, ventilation, and cooling from ramping up simultaneously. Thus, the highest 15-minute power output, which determines the Prix de puissance défini.

Le système de climatisation peut-il être couplé à l’installation photovoltaïque ?

Ja. Läuft die Wärmepumpe bevorzugt bei Sonne, wird der PV-Strom selbst genutzt statt teuer aus dem Netz bezogen. Das Gebäude wirkt als stockage thermique — préchauffé ou pré-refroidi pendant les heures favorables.

Qu’est-ce qu’un jumeau numérique de la technologie de climatisation d’un hôtel ?

Ein Live-Abbild aus den echten Sensoren (Vorlauf, Außentemperatur, Volumenstrom, Leistung, COP), das gegen gelernte Sollbänder prüft, Störungen wie COP-Abfall früh erkennt und in Klartext erklärt, was zu tun ist.
