2AdaptaPAK® Parallel Refrigeration System
Thank You!
The Hillphoenix AdaptaPAK® refrigeration system provides customers with a compact refrigeration
package designed to remove heat from both medium- and low-temperature loads. Such a system,
as selected by the customer, is built to closely match the necessary heat removal capacity. It is a
DX system with a refrigerant charge matched to the needs of the facility where it is installed. Each
The fans and condensing units are sized to provide for sufficient heat rejection under the most
demanding ambient conditions.
Each Unit utilizes a comprehensive controls system which monitors the refrigeration system to
minimize energy and optimize performance.
The controls system allows field networking to the store’s Building Management System. In
addition, local networks may be installed to create coordinated case defrosts on a common
schedule, similar to traditional refrigeration circuits of traditional remote systems.

AdaptaPAK® Parallel Refrigeration System
Section 1:
AdaptaPAK®Product Information
Hillphoenix offers the AdaptaPAK® range of parallel refrigeration systems to
provide customers with an effective alternative to centralized parallel systems.
The various versions of AdaptaPAK® are designed to meet a wide range of
requirements.
AdaptaPAK® Features and Benets
The Hillphoenix AdaptaPAK® parallel system works like any conventional DX refrigeration system, with the main
difference being that there may be one or more individual systems required to serve the full range of refrigeration
loads in a store. The arrangement is different than the installation of one, single, large centralized refrigeration
system, the multiple condensers are an integral part of the unit.
It is also designed specically to improve on the
performance of low and/or medium temperature
refrigeration installations in drug stores, convenience
stores, and other smaller-footprint retail establishments.
An AdaptaPAK® parallel system shares suction,
discharge, and an integrated condenser across several
compressors. As a result, compressor capacity may
be varied to match the required loads—a much more
efcient design.
Multiple, single units with compressors running
constantly at maximum output waste energy and reduce
component life. Parallel installations, on the other hand,
do just the opposite. Because compressor capacities are allowed to vary to match refrigeration loads, there is a
marked savings of energy utilized—20% or more compared to single compressor unit—as well as positive benets on
the live of all system components.
There is also a savings in initial capital outlay with a parallel system. Shared suction, discharge, and an integrated
condenser among compressors virtually guarantees cost savings versus the expense inherent in purchasing
several, self-contained single units. Plus, the single point electrical connection along with a single roof curb and roof
penetration add up to additional savings in installation costs.
Hillphoenix AdaptaPAK® parallel systems are available in a 2 fan unit, a 3 fan unit, and a 4 fan conguration. The
compressors would be arranged in up to two suction groups, with one loop per suction group.

6AdaptaPAK® Parallel Refrigeration System
Whether a 2 fan unit or a 3 fan unit, the AdaptaPAK® system will arrive fully designed for your load conguration,
and ready for placement at the site in your designated pad or roof location. Placement would most commonly be
performed with a cable/rope with proper rigging (refer to drawings for details).The remaining tasks would include
charging with refrigerant, making electrical connections, and completing the connection of the AdaptaPAK® unit up
to your refrigeration loads.
Dimensions of AdaptaPAK® Units
The 2 fan unit is 139 1/4 inches long by 50 1/2 inches wide by 51 1/4 inches high.

DX Refrigeration Systems
Direct expansion (DX) refrigeration is one of the most common methods
used for the removal of heat. Such a system takes heat from a place where
it is unwanted and removes it to a place where it is unobjectionable. The
Hillphoenix® AdaptaPAK® units utilize DX refrigeration to remove heat from
store display cases and walk-in coolers/freezers, and transfer it to an outdoor location where it can be rejected.
Refrigeration Through Vapor Compression
Refrigeration is accomplished through application of various mechanical principles that occur as part of a
continuous cycle, commonly known as the Vapor Compression Refrigeration Cycle.
In the vapor compression cycle, heat is absorbed as the liquid refrigerant in the evaporator changes to a vapor. The
refrigerant boils at the new saturation point in the evaporator (located in the display case or cooler) where it changes
to a superheated vapor. From the evaporator, the superheated refrigerant vapor enters the compressor and the
refrigerant is compressed and changed from a low pressure superheated vapor to a high pressure superheated
vapor (more on this later), It then ows to the condenser. In a simple refrigeration system, the ambient air outside of
the condenser ows through the coils of the condenser where it absorbs heat from the vapor refrigerant causing it to
change back to its liquid state before moving through the metering device where it crosses from the high pressure
side of the system to the low pressure side. On the low pressure side, the refrigerant returns to the evaporator and
the process (refrigeration cycle) is then repeated.
Refrigeration System Components
Knowing how the refrigeration process works helps in understanding where in the sequence of operation the major
components of the mechanical system are, and the functions they perform. Almost any refrigeration system is built
around four main components.
The four main components are:
• Compressor
• Condenser
• Metering Device (also known as an expansion valve)
• Evaporator
Beginning on the next page, these main components are individually presented and discussed.

Compressor
The compressor in a mechanical, vapor compression refrigeration system performs a basic function. It generates the
pressure differential to move the refrigerant through the complete refrigeration cycle. It accomplishes its function in
several simple steps. These steps are:
• The compressor draws in the low pressure refrigerant vapor from the evaporator (compressor suction side).
• Through mechanical means, the compressor compresses the refrigerant vapor to a high pressure.
• The high pressure refrigerant vapor is forced to exit the compressor through a discharge line.
The compressor performs work on the refrigerant by compressing it and raising its pressure and temperature. It thus
adds energy to the refrigerant vapor.
Different types of compressors are used in different systems for various reasons. Some, called reciprocating
compressors, draw the refrigerant into a cylinder, compress it, and then discharge it at a higher pressure. Other types
compress the vapor between mating pairs of off-center scrolls (scroll compressors). Regardless of the method used, all
types of compressors are designed to compress the refrigerant vapor, and thereby increase its pressure and move it
through the refrigeration system.
Condenser
The condenser in a refrigeration system is designed to reject the heat energy that was picked up in the evaporator
and the compressor, and reject it to the cooler outside ambient air. This process causes the high pressure
refrigerant vapor to condense and become a high pressure liquid. The condenser operates as follows:
• The high pressure/temperature refrigerant vapor enters the condenser via the compressor discharge line.
• As the hot vapor enters the condenser and begins to ow through tubes of the condenser coil, lower temperature
ambient air is drawn across the outside of the condenser’s tubes/ns. An operating fan is often used as the
motive force to move the air through the condenser coil.
• Due to the temperature difference, heat is transferred from the hot refrigerant to the cooler ambient air.
• As the hot refrigerant vapor gives up its heat, it changes state (condenses) and becomes a liquid.
• This liquid refrigerant then leaves the condenser via the “liquid line,” and travels to the metering device.
All refrigeration systems utilize a condenser, with one of the most common types being air-cooled. The tubes of the
condenser have copper or aluminum ns attached to them which act to dissipate the heat more effectively (other
materials are used, but copper and aluminum are the most common).
Pressure is controlled in the condenser by a variety of means. On air-cooled condensers, a valve in the condenser’s
return line closes at a preset pressure in order to maintain pressure in the coil. As the pressure increases, the valve
modulates so that a consistent pressure is maintained. The fans that force ambient air through the condenser are
also cycled on and off to assist in the heat transfer process as needed.

Metering Device (Expansion Valve)
After the condenser, the high pressure liquid refrigerant reaches the metering device (expansion valve). The metering
device meters, or controls, the ow of refrigerant from the high pressure, high temperature side of the system to the
low pressure, low temperature evaporator. Important functions include:
• The metering device (expansion valve) regulates how much liquid refrigerant ows and enters the evaporator.
• The small opening for liquid refrigerant ow takes different forms. In some systems the metering device is a
small thin copper tube known as a capillary tube; in others it is a small orice that regulates ow; and in other
refrigeration systems it is a thermostatic expansion valve (TEV or TXV).
• Control of the size of the opening for ow is crucial. It determines how much liquid refrigerant is allowed to
pass. The size of this opening determines the temperature difference that exists between the saturated suction
temperature (SST) and the temperature at the outlet of the evaporator. This temperature difference is so
important that it has its own specic name—superheat.
One of the most common types of metering device is the thermostatic expansion valve (often referred to as a
TXV or TEV). The opening/closing of these valves is controlled by the pressure and temperature at the exit of the
evaporator.
Evaporator
Liquid refrigerant enters the evaporator from the metering device. The evaporator is located in the space that is being
refrigerated. Several things happen in the evaporator:
• The liquid refrigerant entering the evaporator from the metering device (expansion valve) undergoes an
instantaneous large pressure decrease (per the P-T chart, this is also a large temperature decrease).
• As it enters the evaporator, the liquid refrigerant immediately begins to absorb heat from the warm air owing
over the tubes and ns of the evaporator coil.
• With the absorption of heat, the liquid refrigerant also begins to change state (boil) to become a vapor.
• As the refrigerant continues to ow through the tubes of the evaporator, the continued absorption of heat results
in more and more of the liquid refrigerant changing state to become a vapor.
• Prior to its exit from the evaporator, the refrigerant will have completely changed over to the superheated vapor
state, and will then enter the suction line and head back to the compressor.
Inside the evaporator is where the refrigerant absorbs heat to carry it away from the refrigerated space. This could be
the refrigerated space of a display case, a reach-in cooler. or walk-in freezer in which frozen foods are kept.
The basic principle at work here is that heat always moves from areas of higher temperature to areas of lower
temperature. The refrigerant absorbs heat in the evaporator because it is at a lower temperature than the air moving
across the evaporator. This temperature difference (TD) between the refrigerant and the air is approximately 8 to 10 °F.
Other components of refrigeration systems besides these basic ones are mainly just combinations of accessories
and options that expand the capabilities of the system. Several of these are discussed later in this manual.
