Museum display case with filtration system and climate control system

Abstract

A museum display case includes a display space, a filtration system and a climate control system to treat air in the display space. The display case also includes a first air circulation circuit and a second air circulation circuit, which are separate from each other and both originating and terminating in the display space. The filtration system is included in the first air circulation circuit and the climate control system is included in the second air circulation circuit. By providing two independent and separate circulation circuits it is possible to operate such circuits at different intervals, each according to its respective needs, thus avoiding, for example, unnecessary activation of filtration due to the need to intervene on climate control or vice versa.

1 . A museum display case comprising:
 a display space;   a filtration system;   a climate control system for treating air in the display space; and   a first air circulation circuit and a second air circulation circuit, separate from each other and both originating and terminating in the display space, wherein:   the filtration system is included in the first air circulation circuit, and   the climate control system is included in the second air circulation circuit.   
     
     
         2 . The museum display case according to  claim 1 ,
 wherein each said first air circulation circuit and second air circulation circuit comprises:
 a pumping system for moving the air within the air circulation circuit from an intake port facing into the display space to a delivery port facing into the display space. 
   
     
     
         3 . The museum display case according to  claim 2 , wherein the intake port is in a remote position with respect to the delivery port. 
     
     
         4 . The museum display case according to  claim 3 , further comprising at least one opaque vertical wall, wherein:
 each said first air circulation circuit and second air circulation circuit comprises a section extending in the opaque vertical wall, and   one of the intake port and the delivery port is located at a top of the display space, and the other of the intake port and the delivery port is located at a bottom of the display space.   
     
     
         5 . The museum display case according to  claim 4 , wherein:
 the delivery port of the first air circulation circuit and the delivery port of the second air circulation circuit are located at the top of the display space, and   the intake port of the first air circulation circuit and the intake port of the second air circulation circuit are located at the bottom of the display space.   
     
     
         6 . The museum display case according to  claim 2 , further comprising all-transparent vertical walls, wherein:
 the intake port and the delivery port of the first air circulation circuit and the second air circulation circuit are all located at a bottom of the display space.   
     
     
         7 . The museum display case according to  claim 1 , wherein the filtration system comprises at least one passive mechanical filter. 
     
     
         8 . The museum display case according to  claim 1 , wherein the climate control system comprises a compartment containing hygroscopic material and/or a thermal machine, for controlling humidity and/or air temperature.
