This write-up and associated technical bid tabulation (Appendix 1) contain detailed technical review
for the bids of SLIC project refrigeration compressor package. Material requisition for refrigeration
compressor package (1975Z-1-MR-4150-0001-B2) was sent out to two refrigeration compressor
suppliers, namely GEA and York.
Technical bids from both refrigeration compressor suppliers were received and evaluated in detail.
To evaluate the design of refrigeration compression system offered by each supplier, it is crucial to
ensure the available heat duties of refrigerant meet the required process duties. Process duties are:-
a) Evaporator E-6660: 820 kW at -5 deg. C
b) Evaporator E-6580: 1320 kW at -18 deg. C
c) Evaporator E-6582: 550 kW at -50 deg. C
Note that additional margin of 20% (on top of the above mentioned figures) is required by SLIC
Project.
Refrigerant R410A is mandated by SLIC Project for SLIC Refrigeration Compressor Package.
R410A consists 50 weight percent of R32 and 50 weight percent of R125, with an overall molecular
weight 72.6 kg/kmol.
To fully understand the energy balance between the cooling medium and fluids to be cooled, it is
practical to map out the overall refrigeration cycle in Pressure vs. Enthalpy diagram (aka P-H
diagram).
P-H diagram used in this technical evaluation is in accordance with commercially available software,
REFPROP - a reference fluid thermodynamic and transport properties software developed by
National Institute of Standards & Technology (NIST).
Note that enthalpies used in suppliers’ sizing and selection program may not be identical with
REFPROP’s, as the basis for equation of state in REFPROP may be different from suppliers’ sizing
program. This (i.e. basis for equation of state) was discussed with suppliers, they advised that
additional margins are considered in their designs (in addition to 20% margin of heat duty required
by Purchaser) in term of main driver power rating and compressor suction throughput. The purpose
of energy balance check (i.e. enthalpy check) provided in this evaluation is to ensure the flow rates
(for -5 deg. C, -18 deg. C, -50 deg. C and economizing streams) of R410A proposed by suppliers
are within the ballpark figures based on REFPROP.

EVALUATION BASED ON GEA’S TECHNICAL PROPOSAL
P-H diagram below (refer to Appendix 2 for legible version in A4 size landscape mode) is mapped
according to pressure and temperature conditions of refrigeration compressor package offered by
GEA, while enthalpies are calculated from REFPROP.
High stage compressor discharges 80131 kg/hr of R410A at 77.5 deg. C at 24.78 barA (enthalpy =
475.96 kJ/kg), it then gets cooled down to 41 deg. C at full condensate state (according to P-H
diagram). Enthalpy value at this point is 267.98 kJ/kg, which is equivalent to a heat removal duty of
4629 kW. Preliminary calculation reveals that minimum cooling water supply of 803.35 m3/hr is
needed to condense R410A from superheat to full liquid state (assumptions for cooling water as
follow: density = 993 kg/m3, heat capacity at constant pressure = 4.178 kJ/(kg*deg. C), supply
temperature = 33 deg. C, return temperature = 38 deg. C).
23334 kg/hr of liquid R410A (41 deg. C & 24.78 barA) is pressure throttled down to 7.83 barA at
minus 0.6 deg. C (enthalpy = 413.61 kJ/kg) within tube-side of high stage economizer (subsequently
routed back to high stage compressor via high stage compressor side stream nozzle), the stream is
capable to remove 943.9 kW of heat from the shell side of high stage economizer.
Remaining 56797 kg/hr of R410A at 24.78 barA gets further cooling in high stage economizer, from
41 deg. C (enthalpy = 267.98 kJ/kg) down to 6.4 deg. C (enthalpy = 209.78 kJ/kg); equivalent heat
load is 918.2 kW.

R410A stream split-up into two portions, downstream of high stage economizer discharge:-
a) 45735 kg/hr: This stream is further divided into three parts, as elaborated below:-
1) 16669 kg/hr of R410A is piped to customer evaporator E-6660 (-5 deg. C duty). With inlet
condition 6.4 deg. C & 24.78 barA (209.78 kJ/kg), R410A evaporates in tube-side of E-6660
and discharges at -5 deg. C & 6.78 barA (enthalpy = 419.72 kJ/kg); which yields a heat
removal duty of 972 kW. The stream cannot be directly sent back to compressor via
compressor casing side stream; as actual volumetric volume rate proves too much for high
stage compressor, on the other hand the pressure is higher than low stage compressor
discharge pressure. It is therefore commingled (at much lower pressure, 4.3 barA) with
another stream upstream of low stage compressor suction nozzle despite of energy loss
(from 6.78 barA to 4.3 barA), i.e. reduced thermal cycle efficiency.
2) 27641 kg/hr of R410A routes to customer evaporator E-6580 (-18 deg. C duty). With inlet
condition 6.4 deg. C & 24.78 barA (enthalpy = 209.78 kJ/kg), R410A is able to remove 1575
kW of heat from process fluid in E-6580 with discharge condition at -18 deg. C & 4.3 barA,
i.e. vapour dew point (enthalpy = 414.91 kJ/kg).
3) 1425 kg/hr of R410A is pressure throttled in tube-side of inter-cooler. Started-off at 6.4 deg.
C & 24.78 barA (enthalpy = 209.78 kJ/kg), pressure is reduced to 4.3 barA at the tube-side
discharge port; associated discharge temperature at vapour dew point is -18 deg. C
(enthalpy = 414.91 kJ/kg). Heat absorbing capacity for low pressure inter-cooling stream is
81.2 kW. As explained by GEA, the term “inter-cooler” is used (instead of “low stage
economizer”) simply because low pressure economizing stream doesn’t return to
compressor side stream nozzle; it enters compressor suction nozzle (via liquid knock-out
drum). Note that type of inter-cooler is not different from economizer, which is direct
expansion type.
b) 11061 kg/hr: This portion of R410A is further sub-cooled at inter-cooler (pressure profile remains
constant at 24.78 barA), from 6.4 deg. C (enthalpy = 209.78 kJ/kg) down to -11 deg. C (enthalpy
= 183.86 kJ/kg); which contains 81 kW of heat to be removed by inter-cooler. R410A at -11 deg.
C leaves the inter-cooler and enters evaporator E-6582 for final stage process cooling. With a
desired R410A temperature of -50 deg. C at tube-side of E-6582, the associated pressure at
vapour saturation curve is approximately 1.09 barA (enthalpy = 400.02 kJ/kg); it is able to remove
664.2 kW of heat from process fluid in E-6582. A manual inert gas purge unit is included in GEA’s
scope in order to purge out non-condensable fluid at condenser. Non-condensable fluid may
enter the refrigeration loop as a result of near-atmospheric condition at discharge tube-side of E-
6582.

EVALUATION BASED ON YORK’S TECHNICAL PROPOSAL
P-H diagram below (refer to Appendix 3 for legible version in A4 size landscape mode) is mapped
according to pressure and temperature conditions of refrigeration compressor package offered by
York, while enthalpies are calculated from REFPROP.
High stage compressor discharges 76980 kg/hr of R410A at 80.9 deg. C at 25.11 barA (enthalpy =
479.53 kJ/kg), it then gets cooled down to 41 deg. C at full condensate state (refer to P-H diagram,
enthalpy = 268.16 kJ/kg), equivalent heat removal duty is 4519.8 kW. Minimum cooling water supply
of 784.4 m3/hr is needed to condense R410A from superheat to full liquid state (assumptions for
cooling water as follow: density = 993 kg/m3, heat capacity at constant pressure = 4.178 kJ/(kg*deg.
C), supply temperature = 33 deg. C, return temperature = 38 deg. C).
17940 kg/hr of liquid R410A (41 deg. C & 25.11 barA) is pressure throttled down to 10.20 barA at 13
deg. C (enthalpy = 429.42 kJ/kg) within tube-side of high stage economizer (subsequently routed
back to high stage compressor via high stage compressor side stream nozzle), the stream is capable
to remove 803.61 kW of heat from the shell side of high stage economizer (803.61 kW according to
REFPROP). Enthalpy difference according to York’s e-mail explanation (refer to Appendix 4) is 164
kJ/kg, it turns out heat removing capacity is 817 kW.
Remaining 59040 kg/hr of R410A at 25.11 barA gets further cooling in high stage economizer, from
41 deg. C (enthalpy = 268.16 kJ/kg) down to 12 deg. C (enthalpy = 218.45 kJ/kg); equivalent heat

load is 815.24 kW (according to REFPROP). Enthalpy difference according to York’s e-mail
explanation (refer to Appendix 4) is 49.9 kJ/kg, it turns out that 818 kW of heat needs to be removed.
R410A stream split-up into two portions, downstream of high stage economizer discharge:-
a) 48822 kg/hr: This stream is further divided into three parts, as elaborated below:-
1) 17406 kg/hr of R410A is piped to customer evaporator E-6660 (-5 deg. C duty). With inlet
condition 12 deg. C & 25.11 barA (218.45 kJ/kg), R410A evaporates in tube-side of E-6660
and discharges at -5 deg. C & 6.79 barA (enthalpy = 419.71 kJ/kg); which yields a heat
removal duty of 973.09 kW. This stream cannot be directly sent back to compressor via
compressor casing side stream; as actual volumetric volume rate proves too much for high
stage compressor, on the other hand the pressure is higher than low stage compressor
discharge pressure. It is therefore commingled (at much lower pressure, 4.29 barA) with
another stream upstream of low stage compressor suction nozzle despite of energy loss
(from 6.79 barA to 4.29 barA), i.e. reduced thermal cycle efficiency.
2) 28800 kg/hr of R410A routes to customer evaporator E-6580 (-18 deg. C duty). With inlet
condition 12 deg. C & 25.11 barA (enthalpy = 218.45 kJ/kg), R410A is able to remove
1572.4 kW of heat from process fluid in E-6580 with discharge condition at -18 deg. C &
4.34 barA (enthalpy = 415 kJ/kg).
3) 2616 kg/hr of R410A is pressure throttled in tube-side of inter-cooler. Started-off at 12 deg.
C & 25.11 barA (enthalpy = 218.45 kJ/kg), pressure is reduced to 2.53 barA at the tube-
side discharge port; associated discharge temperature at vapour dew point is -27.1 deg. C
(enthalpy = 413.01 kJ/kg). Heat absorbing capacity for low stage economizing stream is
141.38 kW. Enthalpy difference per York’s e-mail explanation (refer to Appendix 4) is 196.1
kJ/kg, it turns out heat removing capacity is 142.5 kW.
b) 10218 kg/hr: This portion of R410A is further sub-cooled at low stage economizer (pressure =
25.11 barA), from 12 deg. C (enthalpy = 218.45 kJ/kg) down to -27.1 deg. C (enthalpy = 160.87
kJ/kg); which contains 163.43 kW of heat to be removed by low stage economizer (Enthalpy
difference according to York’s e-mail explanation in Appendix 4 is 50.2 kJ/kg, it turns out that
142.5 kW of heat needs to be removed). R410A at -27.1 deg. C leaves the low stage economizer
and enters evaporator E-6582 for final stage process cooling. With a desired R410A temperature
of -50 deg. C at tube-side of E-6582, the associated pressure at vapour saturation curve is
approximately 1.09 barA (enthalpy = 400.02 kJ/kg); it is able to remove 678.79 kW of heat from
process fluid in E-6582.

Dear Mr. Xie,

I marked the enthalpy on the chart attached. These data are got from our software.

Following are the capacity we calculated:

It should be no problem for the chart and relative data. And after compared with your data, two data are different:
enthalpy at subcooled refrigerant of low stage economizer and at superheated refrigerant of high stage economizer.

Appendix 5: GEA reference list for R410A refrigeration compressor package

REQ NO.: 1975Z-1-MR-4150-001
PROJECT NAME: SLIC HCL Recycle Project
LOCATION: Shanghai
TITLE: JOB REFERENCE AND BRIEF DESCRIPTION
To: Shanghai Lianheng Isocyanate Co.,Ltd. and Technip Tianchen Chemical Engineering (Tianjin) Co., Ltd.
致：上海联恒异氰酸酯有限公司/ 德希尼布天辰化学工程（天津）有限公司
With reference to job reference list of R410a (-50℃), R410a as worldwide used R22 substitute, after R407c
as R22 substitute, is favoured gradually by A/C and industrial refrigeration in USA and Europe,
关于 R410A 制冷机组（-50℃）的业绩问题， R410A 作为世界上广泛应用的 R22 的替代制冷剂，在继上世纪
90 年代中期提出使用 R407C（HCF 类制冷剂）作替代品后，在美国、欧洲逐渐受到空调、工业制冷制造业的
青睐。
At middle and low temperature application in industrial refrigeration, R22 is employed as one of more popular
refrigerants because of outstanding thermodynamics performance and cheaper cost. Of course, R507 is
another option used at middle and low temperature application. R410a as new substitute, due to high cost
and high requirement for the design and manufacture of the system, is not preferred for domestic clients. It
can be approved by the GEA Freon Job Reference List that we had submitted during bidding.
在工业冷冻中、低温使用工况，具有热力性能优越、价格低等特点的 R22 仍然是国内最广泛选用的制冷剂之一，
同时 R507 也是很常用于中、低温工况，R410A 作为新型制冷剂，由于价格较高，同时高排气压力对压缩机及
其它系统设备设计压力提出较高的要求，很少被国内客户选用，这些可以从我们前期提供的氟利昂低温制冷设
备业绩表中可以被证实。
GEA, as one of the leaders of industrial refrigeration system/equipment supplier, we focus on customized
industrial refrigeration for high-end users. All of refrigerants can be used in our systems, such as R22,
R507,R744(CO2) , R717(Ammonia) etc. R410 as well. GEA pays more attention on optimizing engineering
and manufacturing for refrigeration equipment and system to meet industrial area application. Refrigerant can
be decided by end-users. At the same time, GEA always gives recommendation for our client on refrigerant
selection base on different applications.
对于基伊埃冷冻事业部而言，我们致力于为高端客户提供非标定制工业冷冻设备，我们的设备适用于市面上所
有的制冷剂，如：R410A、R22、R507、R744（CO2）、R717(氨)等等，GEA 更专注于提高我们的制冷设备、
系统的设计、制造能力，从而满足工业领域的应用。对于制冷剂可由业主任意选择，当然 GEA 也会对制冷剂
