This text describes the data presented in the paper: Investigation of equilibrium and dynamic performance of SrCl2-expanded graphite composite in chemisorption refrigeration system 

========================
Introductory information
========================
Files included in the data deposit (include a short description of what data are contained): 

1) the experimental data of SrCl2/NH3 adsorption/desorption when the heat source temperature was 90, 100 and 110 °C, respectively and the ambient temperature was at 20 °C, evaporation temperature at 0 °C.
2) fitting the experimental data for the kinetic equations of SrCl2/NH3 adsorption/desorption 
3) fitting the experimental data using the linear form of the van't Hoff equation, acquiring the equilibrium constant 


Explain the relationship between multiple data sets, if required:



Key words used to describe the data: 
kinetic equations, equilibrium constant, clapeyron equation, desorption, adsorption, SrCl2/NH3,

Methodological information
==========================
A brief method description � what the data is, how and why it was collected or created, and how it was processed:
This work tested the extreme adsorption/desorption processes with different degree of conversion by carrying out desorption and adsorption separately but individually as thoroughly as possible under three different conditions of heat 
source temperature (90 °C, 100 °C, 110 °C) while the ambient temperature at 20 °C and evaporation temeprature at 0 °C. Each process proceeds until it reaches equilibrium rather than a continuous complete cycle.


Instruments, hardware and software used: 
The test rig is a typical single effect chemisorption unit that consists of a cylindrical reactor with a volume of 0.7 L, a 1m high condenser/evaporator with a volume of 0.53 L, a heat source (a heater circulates oil for heat exchange)
and a heat sink (a cryostat uses glycol water as heat exchange fluid). One RTD temperature sensor (Omega PT100, with the Class A tolerance of±(0.15+0.002×T) °C) embedded in the consolidated adsorbent close to the gas channel. 
One thermocouple (K-type with a measurement error of±0.75%) was used to record the temperature of the heat source fluid (oil). Each container was instrumented with one pressure transducer (0–50 bar, Omega PX409-500a, with an 
accuracy of 0.08% BSL), and one differential pressure sensor (Rosemount, with the accuracy of ±0.075%) was mounted at the bottom of the condenser/evaporator and registered the real-time variation of the mass amount of ammonia
in the condenser. To ensure the accuracy of differential pressure sensor, a heat rope was used to wrap on a bypass pipe between the condenser/evaporator and the differential pressure sensor to prevent the formation of liquid ammonia, 
which could significantly influence the measurement accuracy of the differential pressure sensor. A relief valve (up to 30 bar) was located on the test bench for safety concern. The whole test bench was well insulated to minimize heat loss 
during the experiment. All the measured data by various sensors was collected by datataker (DT 85) every 5 seconds.
Matlab was used to fit the data for kinetic equation and van't Hoff equation.
