When gasses are compressed they are at a high energy level.
When compressed gasses are expanded then energy is released and its temperature drops.

Einstein's refrigeration system uses Ammonia vapour to drive and compress Butane vapour from the evaporator to the absorber/condenser. Vapour temperature leaving evaporator (in my example) is 10'C saturation for R600a (390kPa.) and NH3 is superheated Vapour at 10'C and 650kPa.. 

Absorber/condenser condition R600a at 40'C condensing is 1030kPa. NH3 at 10kPa..

(see attachment)

If there is no heat gain or loss in the flow tube to ambient and the “Butane liquid flow feed pipe” between the condenser and evaporator is not attached. (no heat exchanger):

Does the NH3 give up energy to compress the R600a and does the R600a enter the condenser/absorber as a super heated vapour or as a saturated vapour or have I got the whole theory wrong?

My suspicion is that the Butane would remain saturated vapour even as its temperature rises due to the energy exchange between the NH3 and Butane.
