we know that pump is used to deliver to a much higher energy level, and it needs to increase pressure to evaporator pressure. Doesn't mean it boils to higher pressure and temperature in the evaporator. i'm confused with the process of AHT. how can it absorb heat from a space? please help! thank you
Why do pump are placed between evaporator and condenser instead of expansion device in AHT?

It's a typical single stage absorption heat transformer where the process begins at the waste heat that is added at intermediate temperature to the generator to vaporize the refrigerant from the weak solution. The vaporized refrigerant goes to the condenser where it is condensed delivering an amount of heat at low ambient temperature. and then refrigerant leaving the condenser is "pumped" to the evaporator where it is evaporated by means of a quantity of waste heat at intermediate temperature. After this, the refrigerant vapor goes to the absorber where it is absorbed by the solution with high concentration of absorbent coming from the generator, delivering an amount of heat at higher temperature. how can it absorb heat from a space if waste heat delivered to evaporator causes the vaporization? Thank you

AHT Cooling Systems is an Austrian company, active in both branches of industrial refrigeration and deep freezing, while its main areas of business are fridges and deep freezers for supermarkets, ice cream freezers and bottle coolers.

You might have meant something different by those letters. You need to remember that nobody knows what you are talking about until you explain. If we have to look things up, we report back with whatever we find, and that Is what I found.
You should post a link to a picture of the system you are asking about because names of parts sometimes vary.
