Abstract
A vacuum cooling system (10) having a first fluid (21) and a second fluid (70) circulating through the system (10) in separate cycles, said system (10) including a vacuum chamber (1) containing a portion (14) of said first fluid and a volume of gas (42) evaporated from said first fluid portion (14), a first pump means (7) for removing the gas volume (42) from the vacuum chamber (1) to create a vacuum in said vacuum chamber (1), a means for moving (8) said first fluid (21) into said vacuum chamber (1) to replenish the first fluid portion (14) in said vacuum chamber (1), and heat exchanger means (2) for cooling said second fluid (70) over which air is blown in order to cool air in a space.
Claims26
A vacuum cooling system having a first fluid and a second fluid circulating through the system in separate cycles, said vacuum cooling system comprising:
- a vacuum chamber containing a portion of said first fluid and a volume of gas evaporated from said first fluid portion;
- first pump for removing the gas volume from the vacuum chamber to create a vacuum in said vacuum chamber;
- wherein said first fluid is moved into said vacuum chamber to replenish the first fluid portion in said vacuum chamber;
- a mixing chamber located between the first pump and the vacuum chamber for receiving said first fluid portion from the vacuum chamber and for receiving the gas volume from the first pump, said first fluid portion and said gas volume being mixed in said mixing chamber;
- a first heat exchanger for cooling said second fluid over which air is blown in order to cool the air in a space;
- wherein said first fluid has a different composition to said second fluid and said first fluid includes a volatile component.
A vacuum cooling method in a system having a vacuum chamber, a first heat exchanger, a first pump, a mixing chamber located between the first pump and the vacuum chamber, a first fluid and a second fluid circulating through the system, said second fluid moving in a cycle separate to that of the first fluid, said first fluid having a different composition to said second fluid and said first fluid including a volatile component, said method comprising the steps of:
- evaporating a portion of said first fluid in said vacuum chamber to produce a volume of gas inside said vacuum chamber;
- operating said first pump to remove said volume of gas from the vacuum chamber to create a vacuum in said vacuum chamber;
- moving said first fluid into the vacuum chamber to replenish the first fluid portion in said vacuum chamber;
- providing said mixing chamber to receive said first fluid portion from said vacuum chamber and to receive said volume of gas from said first pump and then mixing the first fluid portion and the volume of gas in the mixing chamber;
- and
- providing said first heat exchanger to cool said second fluid over which air is blown in order to cool the air in a space.
