AquaForce 30XA Carrier: It is a series of chillers with a screw compressor, which works with R-134a refrigerant, for a range of capacities between 80 and 500 tons of refrigeration.
It works with a screw compressor.
The screw compressor is semi-hermetic with a double rotor.
All models have two screw compressors.
Operates with refrigerant r134a.
The standard chiller regulates capacity in 15% steps.
Larger models regulate capacity in steps averaging 12%.
The ComfortLink microprocessor controls the operation of the overall unit and several processes simultaneously.
The processes ComfortLink controls include internal timers, readout inputs, analog-to-digital conversions, fan control, display, diagnostic control, output relay control, demand limit, capacity control, main pressure control, and temperature reset.
Performs control of individual external pumps (when configured).
The first compressor starts 1 to 3 minutes after the cooling call.
The ComfortLink microprocessor controls chiller capacity by varying the number of compressors and each load capacity to meet actual dynamic load conditions.

R1224yd is a refrigerant designed for use in centrifugal chillers, binary cycle generators and waste heat recovery heat pumps, blowing agent, spray solvent and cleaning solvent, with low impact on the environment. R1224yd Is ideal replacement for equipment working with R245fa.
What should you know about the R1224yd (Z) in chillers?
In October 2017, the American Society of Heating, Refrigeration and Air Conditioning Engineers (ASHRAE) granted the AGC company the certification for AMOLEA R1224yd.
ASHRAE certification of R1224yd is expected to accelerate its adoption in a wide range of equipment around the world.
It has a very short atmospheric lifetime and therefore a very low GWP value.
Its ODP is almost zero and it possesses the excellent stability required for refrigerants.
R1224yd (Z) refrigerant is a unique substance, which allows partial refrigerant recharge even if refrigerant leaks.
R1224yd (Z) refrigerant has high stability, therefore there is no change in performance and it does not cause problems such as corrosion after prolonged use.
The R1224yd (Z) refrigerant has high efficiency, provides high cycle efficiency, and indirectly contributes to a lower environmental impact through the reduction of electricity consumption.
Companies such as EBARA Refrigeration Equipment & Systems have adopted R1224yd (Z) refrigerant for their RTBA model centrifugal chillers.
Through a retrofit service, R1224yd (Z) refrigerant can be used in existing centrifugal chillers that are installed.
When retrofitting chillers using R245fa refrigerant is required, R1224yd (Z) refrigerant requires some minor parts of the chiller to be replaced.
Since R1224yd (Z) refrigerant is non-flammable and has low toxicity, good safety and reliability can be maintained.
R1224yd (Z) refrigerant is exempt from the Fluorocarbon Emissions Control Act.
R1224yd (Z) refrigerant is easy to handle and has low pressure. R1224yd (Z) refrigerant has the same performance (COP) and cooling capacity as R245fa.
Since R1224yd (Z) refrigerant is non-flammable and low in toxicity, the same safety and reliability as before can be maintained.
Although the effects of R1224yd on elastomers are equivalent to or less than those of R123 and equivalent to those of R245fa, degradation due to elution may occur in some materials..
Remember that plastics and elastomers can exhibit different properties depending on the mix ratio, types and amounts of additives used, and processing conditions.
Can be adapted for the equipment used for HFC-245fa and HCFO-1233zd(E) without changing the design.
The Tokyo National Stadium, the main venue for the last Olympic Games, uses R1224yd for air conditioning with an RTBA turbocooler, manufactured by Ebara Refrigeration.

The Chiller R-32 offer approximately 5 to 8% greater capacity, compared to systems that work with R410a.
What should be known about the use of R-32 as a replacement for R-410A in Chillers?
R32 has better efficiency and around 10% more capacity than R410A, depending on the application and system design.
In a new application, R32 stands out as the most efficient and best performing alternative to R410A.
The charge of R32 is about 20% less, compared to R410A. R32 is a relatively inexpensive single component refrigerant, which means it is easier to recycle.
Due to the high discharge temperatures of R-32, the operating range of Chillers with R32 is limited.
For operation in ambient temperature conditions greater than 45 ° C the best options are R452b or R454b.
Manufacturers have selected R-32 for their scroll-type chillers, due to its lower impact on the environment.
Compared to R410A, the Seasonal Energy Efficiency Ratio (SEER) is said to improve by 10%.
Thanks to its lower A2L flammability rating, the R32 can be safely used in chilled water systems.
Although R454B is preferred by many as its direct replacement for R410A, R32 has the advantage of being a non-proprietary one-component gas, has no slip, and has price and availability advantages over its rival.
R-32 refrigerant is made up of a single component, it is easier to handle and recover than other alternatives such as R454B or R452B.
Also, since the R32 is slip-free, it is not necessary to vacuum the system before each charge.
With the R454B and R452B there is the possibility that a disproportionate amount of a component could escape in the event of a leak.
R32 is likely to remain cheaper than R454B and R452B.
As there is no patent on R32, access and availability is guaranteed through many refrigerant suppliers.
Regarding efficiency, calculations and compressor manufacturers show higher efficiency ratings for R32 than for R454B.
R32 with its GWP of 675 has a significantly higher GWP than R454B (GWP 466), however the lower amount of R32 refrigerant used should be considered.
The process of changing from R410A to R32 in a chiller requires various components and configurations to be adjusted, including the expansion valve, liquid line tubing, suction line, and discharge line.
In the process of changing from R410A to R32 in a chiller, it may present an oversized compressor and it may be necessary to change it.
Currently, R32, R452B, R454B is considered in Chillers with scroll compressor as short-term replacement, and in the longer term to R1234ze, R515B, R516A.

Chillers that work as heat pumps, they offer higher heating temperatures of more than 150 ° C, and greater energy efficiency than traditional fluids.
R-1336mzz (Z) has high chemical stability, despite the unsaturated chemical bond in its molecular structure.
R1336mzz-Z is characterized by its non-flammability and a favorable toxicity profile.
HFO-1336mzz (E) is a non-flammable, low global warming potential (GWP) working fluid that does not deplete the ozone layer.
