Microchannel condensing coils on coolingonly units

Conquest chillers are equipped with microchannel condensing coils allowing excellent heat transfer and a dramatic improvement of corrosion resistance versus conventional tubes in ﬁ ns coils. Microchannel coils are 100% aluminum, therefore avoiding galvanic corrosion which can occur on conventional condensers made with copper tubes and aluminum ﬁ ns. Microchannel coils are also well adapted for dirty environment thanks to their small thickness and ﬁ ns proﬁ le.

Heat pump units coils

The condenser coil is made of aluminum ﬁ ns mechanically bonded to seamless copper tubing and includes integral subcooling circuit. The coils are factory leak tested at 5 Mpa. If the unit is to be installed in a corrosive environment, aluminum ﬁ ns can be pre-coated with epoxy (optional), with minimum thickness of 8µm, in order to withstand 1000 hours of salt spray test according to ISO 9227.

Electronic Expansion Valve

Electronic expansion valve enables tight chilled water temperature control and low superheat, resulting in more efﬁ cient full-load and part-load operation.

Application versatility

Application Considerations

Certain applications contraints should be considered when sizing, selecting and installing Conquest aircooled Scroll chillers. Unit and system reliability often depend on proper and complete compliance with those considerations.

Unit Size

Unit oversizing is often not recommended since erratic unit operation and excessive compressor cycling are often a direct result of an oversized chiller. If oversizing is desired, consider the alternative of multiple units, splitting the total capacity.

Water Treatment

The use of untreated or improperly treated water in chillers may result in scaling, erosion, corrosion, and algae or slime buildup. This will adversely affect heat transfer between the water and system components. Proper water treatment must be determined locally and depends on the type of system and local water characteristics.

Neither salty nor brackish water is recommend for use in Trane air-cooled Conquest chiller. Usage of either will lead to a shortened life. Trane encourages the employment of a qualiﬁ ed water treatment specialist, familiar with local water conditions, to assist in the establishment of a proper water treatment program.

Foreign matter in the chilled water system can also increase pressure drop and, consequently, reduce water ﬂ ow. For this reason it is important to thoroughly ﬂ ush all water piping to the unit before making the ﬁ nal piping connections to the unit.

Effect of the altitude on the cooling capacity

At elevations substantially above sea level, the decreased air density will decrease condenser capacity and, therefore, unit capacity and efﬁ ciency.

Water ﬂ ow limits

The minimum water ﬂ ow rates are given in the General Data section of this catalog. Evaporator ﬂ ow rates below the tabulated values will result in laminar ﬂ ow causing freeze-up problems,scaling, stratiﬁ cation and poor control. The maximum evaporator water ﬂ ow rate is also given. Flow rates exceeding those listed may result in very high pressure drop across the evaporator.

Flow Rates Out of Range

Many process cooling jobs require ﬂ ow rates that cannot be met with the minimum and maximum published values within the Conquest chiller evaporator. A simple piping change can alleviate this problem. For example: a plastic injection molding process requires 5.0 l/s of 10°C water and returns that water at 15.6°C. The selected chiller can operate at these temperatures, but has a minimum ﬂ ow rate of 6.6 l/s. The system layout in Figure 7 can satisfy the process.

L = Load P = Pump

Flow Proving

Trane provides a factory-installed water ﬂ ow switch monitored by chilller controller CH535 which protects the chiller from operating in loss of ﬂ ow conditions.

Leaving Water Temperature Limits

Trane air-cooled Conquest chillers have two distinct leaving water categories:

• standard, with a leaving solution range of 5.5 to 18°C

• low temperature process cooling, with leaving solution range of -12 to 18°C

Since the leaving solution temperature below 5.5°C results in suction temperature at or below the freezing point of water, a glycol solution is required for all low temperature.

Consult your local Trane sales engineer for applications or selections involving low temperature. The maximum water temperature that can be circulated through the CGAX evaporator when the unit is not operating is

51.7°C. For the model CXAX the water temperature

limit is 60°C. Evaporator damage may result above this temperature.

Application Considerations

Supply Water Temperature Drop

Full load chilled water temperature drops from 3.3 °C to 10°C may be used as long as minimum and maximum water temperature and minimum and maximum ﬂ ow rates are not violated.

Temperature drops outside this range at full load conditions are beyond the optimum range for control and may adversely affect the microcomputer’s ability to maintain an acceptable supply water temperature range. Furthermore, full load temperature drops of less than

3.3°C may result in inadequate refrigerant superheat which is critical to long term efﬁ cient and reliable operation.

Sufﬁ cient superheat is always a primary concern in any refrigerant system and is especially important in a packaged chiller where the evaporator is closely coupled to the compressor.

Parameters which inﬂ uence the water temperature stability:

• Ambient temperature and water temperature (modify cooling capacity)

• Number of capacity steps

• Minimum time between starts of a compressor

• Control dead band

• Water loop volume

• Load ﬂ uctuations

• Fluid type or percentage of glycol

Typical Water Piping

All building water piping must be ﬂ ushed prior to making ﬁ nal connections to the chiller. To reduce heat loss and prevent condensation, insulation should be applied. Expansion tanks are also usually required so that chilled water volume changes can be accommodated.

Avoidance of Short Water Loops

Adequate chilled water system water volume is an important system design parameter because it provides for stable chilled water temperature control and helps limit unacceptable short cycling of chiller compressors.

The Conquest Air Cooled chiller’s temperature control sensor is located in the supply (outlet) water connection or pipe. This location allows the building to act as a buffer to slow the rate of change of the system water temperature. If there is not a sufﬁ cient volume of water in the system to provide an adequate buffer, temperature control can suffer, resulting in erratic system operation and excessive compressor cycling.

Typically, a two-minute water loop circulation time is sufﬁ cient to prevent short water loop issues. Therefore, as a guideline, ensure the volume of water in the chilled water loop equals or exceeds two times the evaporator ﬂ ow rate. For systems with a rapidly changing load proﬁ le the amount of volume should be increased.

If the installed system volume does not meet the above recommendations, the following items should be given careful consideration to increase the volume of water in the system and, therefore, reduce the rate of change of the return water temperature.

• A volume buffer tank located in the return water piping.

• Larger system supply and return header piping (which also reduces system pressure drop and pump energy use).

An optional factory-installed buffer tank is designed to meet the minimum two minute loop time without additional job site piping. The buffer tank can also be used on jobs that already meet or exceed the minimum loop time to further reduce the potential for compressor cycling, increasing the compressor life span, and reducing system temperature ﬂ uctuations.

CG-PRC026C-GB

Application Considerations

Minimum water volume for a process application

If a chiller is attached to an on/off load such as a process load, it may be difﬁ cult for the controller to respond quickly enough to the very rapid change in return solution temperature if the system has only the minimum water volume recommended. Such systems may cause chiller low temperature safety trips or in the extreme case evaporator freezing. In this case, it may be necessary to add or increase the size of the mixing tank in the return line or consider the optional factoryinstalled buffer tank with the chiller. Some guidance on calculating the minimum volume necessary for proper Scroll Compressors Chillers operation are given here, through a simpliﬁ ed formula, which does not take in account variations on chiller efﬁ ciency, compressor sequencing, evaporator inlet/outlet temperature.

Multiple Unit Operation

Whenever two or more units are used on one chilled water loop, Trane recommends that their operation be coordinated with a higher level system controller for best system efﬁ ciency and reliability. The Trane Tracer system has advanced chilled plant control capabilities designed to provide such operation.

CG-PRC026C-GB

Unit Placement

Setting The Unit

A base or foundation is not required if the selected unit location is level and strong enough to support the unit’s operating weight (see “Weights” section of this catalog).

For a detailed discussion of base and foundation construction, refer to the sound engineering bulletin or the unit IOM. Manuals are available through the local Trane ofﬁ ce.

HVAC equipment must be located to minimize sound and vibration transmission to the occupied spaces of the building structure it serves. If the equipment must be located in close proximity to a building, it should be placed next to an unoccupied space such as a storage room, mechanical room, etc. It is not recommended to locate the equipment near occupied, sound sensitive areas of the building or near windows. Locating the equipment away from structures will also prevent sound reﬂ ection, which can increase sound levels at property lines or other sensitive points.

Isolation and Sound Emission

Structurally transmitted sound can be reduced by elastomeric vibration eliminators. Elastomeric isolators are generally effective in reducing vibratory noise generated by compressors, and therefore, are recommended for sound sensitive installations. An acoustical engineer should always be consulted in critical situations.

Figure 9 - Installation example

For maximum isolation effect, water lines and electrical conduit should also be isolated. Wall sleeves and rubber isolated piping hangers can be used to reduce the sound transmitted through water piping. To reduce the sound transmitted through electrical conduit, use ﬂ exible electrical conduit.

Local codes on sound emissions should always be considered. Since the environment in which a sound source is located affects sound pressure, unit placement must be carefully evaluated. Sound power levels for chillers are available on request.

Servicing

Adequate clearance for evaporator and compressor servicing should be provided. Recommended minimum space envelopes for servicing are located in the dimensional data section and can serve as a guideline for providing adequate clearance. The minimum space envelopes also allow for control panel door swing and routine maintenance requirements. Local code requirements may take precedence.

Unit Location

General

Unobstructed ﬂ ow of condenser air is essential to maintain chiller capacity and operating efﬁ ciency. When determining unit placement, careful consideration must be given to assure a sufﬁ cient ﬂ ow of air across the condenser heat transfer surface. Two detrimental conditions are possible and must be avoided: warm air recirculation and coil starvation. Air recirculation occurs when discharge air from the condenser fans is recycled back to the condenser coil inlet. Coil starvation occurs when free airﬂ ow to the condenser is restricted.

Condenser coils and fan discharge must be kept free of snow or other obstructions to permit adequate airﬂ ow for satisfactory unit operation. Debris, trash, supplies, etc., should not be allowed to accumulate in the vicinity of the air-cooled chiller. Supply air movement may draw debris into the condenser coil, blocking spaces between coil ﬁ ns and causing coil starvation.

Both warm air recirculation and coil starvation cause reductions in unit efﬁ ciency and capacity because of the higher head pressures associated with them. The air-cooled Conquest chiller offers an advantage over competitive equipment in these situations. Operation is minimally affected in many restricted air ﬂ ow situations due to its advanced chiller controller.

Microprocessor which has the ability to understand the operating environment of the chiller and adapt to it by ﬁ rst optimizing its performance and then staying on line through abnormal conditions. For example, high ambient temperatures combined with a restricted air ﬂ ow situation will generally not cause the air-cooled model CGAX chiller to shut down. Other chillers would typically shut down on a high pressure nuisance cut-out in these conditions.

Cross winds, those perpendicular to the condenser, tend to aid efﬁ cient operation in warmer ambient conditions. However, they tend to be detrimental to operation in lower ambients due to the accompanying loss of adequate head pressure. Special consideration should be given to low ambient units. As a result, it is advisable to protect air-cooled chillers from continuous direct winds exceeding 4.5 m/s in low ambient conditions.

Chiled water piping should be supported.

Unit Placement

Provide Sufﬁ cient Unit-to-Unit Clearance

Units should be separated from each other by sufﬁ cient distance to prevent warm air recirculation or coil starvation. Doubling the recommended single unit air-cooled chiller clearances will generally prove to be adequate.

Walled Enclosure Installations

When the unit is placed in an enclosure or small depression, the top of the surrounding walls should be no higher than the top of the fans. The chiller should be completely open above the fandeck. There should be no roof or structure covering the top of the chiller. Ducting individual fans is not recommended.
