HemaCool®Operating Instruction

1-1 REV 2

CHAPTER 1. INTRODUCTION

Section I. System Familiarization

a. The HemaCool®is a conventional liquid/vapor-phase refrigerator with a number of special enhancements:

(1) HemaCool®employs vacuum insulation panels to decrease the power required to regulate temperature in a given

environment, to increase holdover time when energy sources are lost or disconnected, and to increase internal

temperature stability.

(2) In the COOL mode (4°C (39ºF) set point), the unit prevents payload freezing in sub-zero environments by

applying heat, rather than cooling.

(3) The unit's control system works with a number of different power sources without special adapters. This power

system includes internal batteries that allow the HemaCool®to operate for a time without external power (see

Operational Specifications, Paragraph 1-4).

(4) The HemaCool®includes integral monitoring and logging of payload compartment temperature and battery

charging state.

(5) The HemaCool's®internal design is arranged to accept baskets for holding blood bags (or fresh frozen plasma

bags when the unit is operating in freezer mode).

(6) Small internal fans help circulate cooling air, to maintain uniform temperature.

b. The HemaCool®is designed to preserve liquid or frozen blood products and medical supplies. HemaCool®provides

exceptional field storage through its combination of superior insulation technology and temperature controls, based

on microcontroller solid-state electronics.

c. The HemaCool®is portable and self-powered, utilizing internal batteries. The system will accept electrical power

from multiple sources, e.g., 12-28 VDC from batteries or other DC sources at the DC power input, or from a wide

range of grid power standards (any combination of 100-250 VAC and 50-60 Hz line frequencies) at the AC power

input.

d. If the unit is fully stocked with conditioned contents and no power is applied (unit off), it will take more than 2 hours

for the internal payload temperature to rise from 4°C (39°F) to 6°C (43°F) in an ambient temperature of 49°C

(120°F).

(1) The HemaCool®will perform in either the COOL or FREEZE mode.

(a) In the COOL mode (4°C (39°F)), the unit, provided its two internal 21-amp-hour batteries are properly

charged, will maintain a temperature range of 1°C (34°F) to 6°C (43°F) for more than 24 hours at 24°C

(75°F) ambient temperature.

(b) In FREEZE mode (-22°C (-7°F)), the unit, provided its two internal 21 amp-hour batteries are properly

charged, will keep blood products frozen for more than 8 hours, at an ambient temperature of 24°C (75°F).

Freeze mode operation does, however, reduce the battery-powered hold time. (See Operational

Specifications, Paragraph 1-4).

(2) For additional payload security, the HemaCool®is also equipped with an internal heater that will prevent a

refrigerated payload from freezing if the unit is in an environment that is below 1°C (34°F), but no lower than

-20°C (-4°F).

e. The standard default temperature scale setting for the HemaCool®is Celsius (°C).

NOTE

This manual assumes that when viewing the HemaCool®, the front is the side with the

internal lid latches. The display screen is on the left when viewed from the front. Viewed

from the front, the compressor and electronics compartment is on the left side of the

machine, while the batteries are under the cover panel on the right side.

The HemaCool®is ergonomically designed for quick response operation in the world’s harshest operating environments and

incorporates the following features. Figure 1-1 illustrates these features.

a. Tough Mil-Spec Case (1).

b. Six tie-down-rated carry handles for two- or four-person carry transportation (2).

c. Ten positive locking latches for secure storage and transport (3).

d. Power panel for control and connection to external power sources (4).

e. Display and control panel for operator interface (5).

f. Easy load/unload baskets that allow convection around packs for even cooling (6).

g. Vacuum panel insulated lid (7).

h. A cover panel to store all required cables and accessories (8).

i. The HemaCool®can be stored in temperatures from -30ºC (-22ºF) to 65ºC (149ºF).

1-3. PHYSICAL SPECIFICATIONS

1-4. OPERATIONAL SPECIFICATIONS

HemaCool®Operating Instruction

1-5 REV 2

a. Figure 1-2 is a functional block diagram of the HemaCool®as described below.

b. In normal operation, the evaporator temperature sensor (Figure 1-2) is monitored by the control board processor chip,

which compares its output to an internal look-up table. This table lists the evaporator temperatures that the

compressor should turn on and off to maintain the temperature selected on the power panel. The on/off function is

performed by an optically isolated MOSFET switch on the control board that is routed to the compressor through the

power board. This switch acts in place of the conventional thermostat switch to tell the compressor driver to run the

compressor and fans.

c. The compressor can operate in two speed settings: slow or fast. Each time the compressor is started, it runs in slow

speed. If the compressor runs continuously for 2 minutes, and the temperature has still not reached the desired target,

the compressor switches to fast speed. It continues to run in fast speed until it cycles, or is turned off.

d. When the control temperature selection is changed, it tells the control board processor to use a different look-up table.

e. Because thermal contact between the evaporator and the payload is made through air circulated by the internal fans, it

is imperfect. In above 0ºC (32ºF) ambient temperatures, this means the evaporator runs cooler than the payload

temperature. The only exception is when the heater operates to prevent payload freezing in outside ambient

temperatures of below 0ºC (32ºF).

f. Because of the temperature difference between the payload and the evaporator, as well as to have faster response, the

temperature sensor for the evaporator is separate from the payload compartment temperature sensor and mounted

directly on the evaporator.

g. The payload compartment temperature sensor is monitored by the microprocessor to alert it to any failure of the

temperature regulating system and to generate the temperature readout in the display. Temperature information

supplied to the data logger is provided by the payload, evaporator, and ambient sensors.

h. The processor takes a new reading of the temperature (and also of battery voltage) every 1.25 seconds. It averages

eight readings before updating the display. This means the display updates every 10 seconds.

i. When the unit is operating on DC from its batteries or DC auxiliary power, the internal and external fans operate only

when the control board operates the compressor.

j. When AC power is available, the AC to DC converter runs constantly to keep the batteries charged, and the

condenser coil blower runs constantly to exhaust heat from the converter. The internal fans are switched through a

magnetic reed switch operated by the payload compartment lid. If the lid is open, the internal fans are turned off to

prevent the mixing of outside air with the payload.

k. The control board determines which power source is used to operate the unit. This ensures the AC supply takes over

for the batteries and charges them during operation. A manual temperature or other change may not be displayed for

10 seconds.
