Mitsubishi P-Series Server

TRUST COMBINED COMFORT SYSTEMS AND MITSUBISHI ELECTRIC PRECISION COOLING EQUIPMENT TO PROVIDE UNPARALLELED RELIABILITY AND TEMPERATURE CONTROL FOR ONE OF YOUR MOST VALUABLE ASSETS

SERVER ROOM CLIMATES DEMAND COOLING MECHANISMS DESIGNED SPECIFICALLY TO MEET THEIR UNIQUE NEEDS. THAT IS WHY IT IS IMPERATIVE TO INSTALL A COMMERCIAL-GRADE SERVER ROOMS COOLING SYSTEM THAT IS DURABLE, EFFICIENT AND RELIABLE. THAT’S THE P-SERIES PRECISION COOLING SYSTEM FROM MITSUBISHI ELECTRIC.

COMMERCIAL VS. RESIDENTIAL GRADE TECHNOLOGY

Some modified residential units claim to be sufficient for server room applications. However, these units, designed for comfort cooling in residential applications, are not equipped to endure the strain placed on them by the continuous sensible heat load of server rooms.This could result in potentially reduced lifespan, higher servicing costs and, ultimately, expensive early system failure.
Mitsubishi Electric’s P-Series commercial grade precision cooling system is different: its durable design means it can withstand around the clock usage and extreme conditions. At the core of the system is a commercial grade variable speed compressor designed specifically for durability and to maintain consistent, reliable server room temperature.

PRECISION COOLING VS. COMFORT COOLING

The key advantage of the P-Series system is how it delivers cooling. Residential grade systems, though modified, are primarily designed to remove humidity in an environment to a level comfortable for humans, otherwise known as comfort cooling.
As a result, only 60 – 70% of their operation is dedicated to lowering temperature. But server rooms generate dry heat, meaning there is less need for humidity removal. The P-Series precision cooling system is designed for removal of sensible heat, first and foremost. As a result, it is capable of effectively removing the vast amount of sensible heat load in a server room, which is equivalent to 80 – 90% of the total cooling requirement.

SEASONAL VS. CONSTANT COOLING

The compressors in residential units are not designed to deliver cooling in Canadian winters. Running them continuously during extreme cold conditions can lead to excessively low condensing pressure, which can result in a series of malfunctions and potential compressor failure. The P-Series features proven Low and Ultra Low Ambient cooling operations that are specifically designed for the Canadian climate, so they continue to operate efficiently and effectively even when outside temperatures reach as low as -40°C.

THE BENEFITS OF A VARIABLE SPEED INVERTER SCROLL COMPRESSOR

Conventional compressors typically only run at one speed and can only cycle between on and off – not an effective method for delivering cooling in a server room. The P-Series is equipped with Mitsubishi Electric’s quality-made, durable variable speed inverter scroll compressor that can adjust its speed to provide precise cooling as needed.

This means:

  • a consistent, precise temperature is maintained at all times
  • increased energy efficiencies, resulting in cost savings
  • when a server room expands, the P-Series can adapt to the increasing heat load without requiring the installation of additional equipment.

DESIGN FLEXIBILITY

Unlike many ductless cooling systems with maximum pipe lengths of 65 feet, P-Series accommodates extra-long pipe lengths of up to 165 feet. This provides enough flexibility for the condenser and evaporator to be installed strategically to suit the overall design and functionality requirements of the commercial space. In addition, our Twin System can accommodate larger or odd shaped server rooms by allowing two indoor units to operate simultaneously with a single outdoor unit. As a result, temperatures remain consistent throughout the room with no corner left uncooled.

P-SERIES ADVANTAGES VS. RESIDENTIAL UNITS

P-SERIES RESIDENTIAL UNITS
  • Sensible Heat Ratio of 80 – 90%. (precision cooling)
  • Durability & Reliability 24/7 in commercial applications.(commercial-grade components)
  • Effective even when outdoor ambient temperature reaches -40°C. (proprietary ultra low ambient technology)
  • Sensible Heat Ratio of only 60 – 70%. (comfort cooling)
  • Prone to failure in commercial applications. (residential-grade components)
  • Loses effectiveness in low ambient outdoor conditions.(not built to deliver cooling in Canadian winters)
