The Liebert GLYCOOL free-cooling system is inte- grated with a glycol cooled Challenger 3000.

At outdoor temperatures below 35°F (1.6°C), the GLYCOOL coil is capable of providing total system capacity. At outdoor temperatures between 35° and 65°F (1.6° and 18.3°C), the unique modulating valve permits partial cooling of the space by the GLY- COOL coil with the DX system picking up the rest of the load. Above 65°F (18.3°C) the unit functions as a glycol unit and all the cooling is accomplished by the DX system. When cooling is required, the three-way modulating valve and water regulating valve direct glycol (from the heat rejection loop) to the Econ-O-Coil located upstream of the evaporator coil, to the condenser, or to both.

The GLYCOOL system contains all the standard fea- tures of a glycol cooled system plus the following.

A solid-state temperature monitor compares the room air temperature and entering glycol temperature. When air temperature is higher than glycol tempera- ture, the monitor communicates to the microproces- sor control that “free-cooling” is available.

The GLYCOOL coil is strategically located in the return air stream of the environmental control system. This coil is designed for closed-loop applications using properly treated glycol solutions.

The air is first filtered before entering the coil and then is either precooled or totally cooled before enter- ing the refrigeration coil. The glycol flow to the coil is controlled by a pre-piped modulating three-way valve. When supplied with a 45°F (7.2°C) glycol solu- tion, the coil is sufficiently sized to offer the identical cooling capacity as is obtained during the refrigera- tion cycle of the compressor.

The GLYCOOL Three-Way Control Valve opens full anytime the temperature of the glycol solution is below room temperature, to take full advantage of all possi- ble free cooling. As the outdoor ambient drops, the three-way control valve modulates the flow to the GLYCOOL coil. It maintains constant temperature in the room and includes operating linkage and electronic motor. Unlike other valves of this nature, there is no over travel linkage or end switches to be adjusted.

A head pressure operated glycol regulating valve accurately controls the condensing temperature and system capacity for various entering glycol tempera- tures. The valve has three-way action.

The Liebert manufactured drycooler is constructed of aluminum with a copper tube aluminum fin coil. The low profile design features multiple direct drive pro- peller type fans, balanced to the heat rejection load. An integral, factory wired and tested control panel reduces installation time.

The dual pump package features two full size glycol pumps, each capable of providing sufficient flow for system operation. A flow switch will sense the loss of flow, should the lead pump fail, and automatically command the standby pump to start. The complete system includes dual pump housing, pumps, lead-lag switch and flow switch (for field installation). The dual pump package provides redundancy, protecting against costly downtime in the computer room.
