Air-conditioning apparatus for indoor environments

Abstract

An air-conditioning apparatus for air conditioning indoor environments has a containment structure having a casing delimiting a first compartment and a second compartment. A pellet stove configured to operate in heating mode and provided with a first duct for movement of combustion air in input to the pellet stove is housed inside the first compartment. A monoblock portable heat pump configured to operate in heating and/or cooling mode and provided with a second duct for movement of heated air in output from the monoblock portable heat pump is housed inside the second compartment.

What is claimed is: 
     
         1 . An air-conditioning apparatus for air conditioning indoor environments, comprising a containment structure having a casing delimiting a first compartment and a second compartment,
 wherein a pellet stove is housed inside the first compartment, configured to operate in heating mode and provided with a first duct for movement of combustion air in input to the pellet stove, and   wherein a monoblock portable heat pump is housed inside the second compartment, configured to operate in heating and/or cooling mode and provided with a second duct for movement of heated air in output from the monoblock portable heat pump.   
     
     
         2 . The air-conditioning apparatus of  claim 1 , wherein the pellet stove and the monoblock portable heat pump operate independently and have no mechanical parts in common. 
     
     
         3 . The air-conditioning apparatus of  claim 1 , wherein the first compartment and the second compartment are airtight. 
     
     
         4 . The air conditioning apparatus of  claim 1 , wherein the first duct and the second duct are mechanically and fluidically separated from each other. 
     
     
         5 . The air-conditioning apparatus of  claim 1 , wherein the first duct and the second duct are connected to a junction box, which is connected to an outlet hole of the air-conditioning apparatus connected to an outdoor environment. 
     
     
         6 . The air-conditioning apparatus of  claim 5 , wherein the outlet hole is fluid-dynamically connected with a corresponding hole arranged on a wall of an indoor environment by an outlet duct. 
     
     
         7 . The air conditioning apparatus of  claim 5 , wherein in the junction box a valve is found for alternately opening and closing the first duct and the second duct. 
     
     
         8 . The air-conditioning apparatus of  claim 7 , wherein in a heating operating mode with the pellet stove, the valve closes the second duct, while in a cooling operating mode with the monoblock portable heat pump, the valve closes the first duct. 
     
     
         9 . The air-conditioning apparatus of  claim 7 , wherein the first duct and the second duct are not connected to each other and are in communication only and exclusively with the outdoor environment by the valve, which allows an airtight operation and installation. 
     
     
         10 . The air-conditioning apparatus of  claim 7 , wherein the valve is configured so that, when using the air-conditioning apparatus in the heating operating mode with the pellet stove, the valve closes the outlet duct towards an outside of the monoblock portable heat pump. 
     
     
         11 . The air-conditioning apparatus of  claim 1 , wherein the first duct and the second duct are connected to each other with a “Y” fitting or with a “T” fitting. 
     
     
         12 . The air-conditioning apparatus of  claim 1 , wherein the first duct and the second duct are connected by a concentric fitting, where a coaxial pipe is connected, to put the air-conditioning apparatus in communication with an outdoor environment. 
     
     
         13 . The air-conditioning apparatus of  claim 1 , wherein the first compartment houses a storage tank for solid biomass fuel, an auger for movement of the solid biomass fuel, a combustion chamber, a brazier, an electric igniter, a first fan or fume extractor for the movement of combustion air in suction and subsequent evacuation of combustion fumes, and a second fan for movement of indoor air drawn from an indoor environment which is heated before being reintroduced in the indoor environment. 
     
     
         14 . The air-conditioning apparatus of  claim 1 , wherein the second compartment houses a condenser, a third fan for movement of air drawn from an indoor environment which absorbs heat released by the condenser before exiting towards an outdoor environment by a pipe, an evaporator, and a fourth ventilator for movement of air drawn from the indoor environment which is cooled and dehumidified, yielding heat to the evaporator before being reintroduced in the indoor environment.
