In a system for air-conditioning interior spaces of a building which are connected via at least one exhaust air duct, one or more interior spaces are provided with an air-conditioning unit which has a inlet line of outdoor air, which supplies inlet air or circulating air to the interior space or spaces, and which is connected to a fluid circuit of a heat pump. The exhaust air duct and a further fluid circuit of the heat pump are connected to an energy store installed outside the building, wherein the energy store is connected to a heat exchanger in a liquid reservoir for energy transfer and for energy storage, which is connected via the heat exchanger to another fluid circuit of the heat pump, the exhaust air being directed into the liquid reservoir via a heat exchanger.

An apparatus and a method for detecting refrigerant leakage in an air source heat pump system. The method for detecting refrigerant leakage in an air source heat pump system includes the following steps in a cooling mode: S110: obtaining a running parameter of an air source heat pump system, wherein the running parameter at least includes a compressor rotational speed; S120: comparing the running parameter with a preset running parameter range; S130: updating a cumulative score when the running parameter falls within the preset running parameter range; and S140: when the cumulative score exceeds a predetermined cumulative score, determining that refrigerant leakage occurs, and when the cumulative score does not exceed the predetermined cumulative score, return to step S110.
