Abstract
Novel sorption cooling devices capable of providing cooling over an extended period of time are disclosed. The sorption cooling devices are particularly useful for temperature-controlled shipping containers that are required to maintain a temperature below ambient for a time sufficient to complete delivery of the container and its contents. The shipping containers can be utilized to cost-effectively transport temperature-sensitive products.
Claims15
A sorption cooling device, comprising:
- a) an evaporator for providing cooling;
- b) an absorber adapted to absorb vapor from said evaporator;
- c) a first reservoir adapted to contain a first refrigerant liquid;
- d) a second reservoir adapted to contain a second refrigerant liquid;
- e) means for supplying liquid from said first reservoir to said evaporator at a first liquid flow rate;
- and
- f) means for supplying liquid from said second reservoir to said evaporator at a second liquid flow rate, wherein the first liquid flow rate is faster than said second liquid flow rate.
A method for operating a sorption cooling device having an evaporator for providing cooling and an absorber for absorbing vapor formed in the evaporator, comprising the steps of providing a first portion of liquid to said evaporator at a first liquid supply rate and providing a second portion of liquid to said evaporator at a second liquid supply rate that is lower than said first liquid supply rate.
