Refrigeration Apparatus

Abstract

Refrigeration apparatus which includes: an evaporator ( 37 ), a compressor ( 33 ) and a condenser ( 38 ), connected by pipe work in a known manner, a fan ( 34 ) and a tray ( 35 ) arranged to collect water during defrost cycle of the apparatus; wherein: a) at least the compressor ( 33 ), condenser ( 38 ), fan ( 34 ) and tray ( 35 ) are contained with in a housing ( 36 ) which is substantially closed except for air vents ( 36 a, 36 b ); b) at least part of the pipe work between compressor ( 33 ) and the condenser ( 38 ) is arranged to pass through the tray ( 35 ); c) the fan ( 34 ), housing ( 36 ) and tray ( 35 ) are designed and arranged such that in use the fan ( 34 ) moves air through the housing ( 36 ) so that substantially all of the air is directed over the surface of the tray ( 35 ).

1 . Refrigeration apparatus which includes:
 an evaporator, a compressor and a condenser, connected by pipework in known manner, a fan, and a tray arranged to collect water during the defrost cycle of the apparatus;   wherein:   a) at least the compressor, condenser, fan and tray are contained within a housing which is substantially closed except for air vents;   b) at least part of the pipework between the compressor and the condenser is located within the tray;   c) the condenser is located in the tray:   d) the fan, housing and tray are designed and arranged such that in use the fan moves air through the housing so that substantially all of the air is directed over the surface of the tray.   
   
   
       2 . The refrigeration apparatus as claimed in  claim 1 , wherein the condenser is provided with cooling fins having a spacing not more than 60 fins/metre. 
   
   
       3 . The refrigeration apparatus as claimed in  claim 1  or  claim 2 , wherein the fan is located at the front of the housing and is designed to blow air through the housing. 
   
   
       4 . The refrigeration apparatus as claimed in  claim 1  or  claim 2 , wherein the fan is located at the rear of the housing and is designed to draw air through the housing. 
   
   
       5 . (canceled) 
   
   
       6 . (canceled) 
   
   
       7 . The refrigeration apparatus as claimed in  claim 1 , wherein the evaporator also is contained within the housing, and the housing and its contents are designed as a removable cassette which can be withdrawn from the remainder of the refrigeration apparatus without dismantling the apparatus. 
   
   
       8 . Refrigeration apparatus which includes:
 an evaporator, a compressor and a condenser connected by pipework in known manner, a fan, and a tray arranged to collect water during the defrost cycle of the apparatus;   wherein:   a) the evaporator, compressor, condenser, fan and tray are contained within a housing which is substantially closed except for air vents;   b) the condenser is located in the tray;   c) the fan is located at the front of the housing and is designed to blow air through the housing;   d) the fan, housing and tray are designed and arranged such that in use the fan blows air through the housing so that substantially all of the air is directed over the surface of the tray.   
   
   
       9 . Refrigeration apparatus which includes:
 an evaporator, a compressor and a condenser, connected by pipework in known manner, a fan, and a tray arranged to collect water during the defrost cycle of the apparatus;   wherein:   a) the evaporator, compressor, condenser, fan and tray are contained within a housing which is substantially closed except for air vents;   b) the fan is located at the rear of the housing and is designed to draw air through the housing;   c) the fan, housing and tray are designed and arranged such that in use the fan moves air through the housing so that substantially all of the air is directed over the surface of the tray;   d) at least part of the pipework between the compressor and the condenser is located within the tray;   e) the condenser is located in the tray.
