Because of the constant heat load, cooling is required throughout the year. Both the ComPac I and ComPac II air conditioners have the necessary controls and safeties for operation in hot or cold weather.

The primary difference in the two units is the factory installed economizer in the ComPacThe economizer cycle uses outside air, when cool and dry, to cool theThe economizer cycle can reduce run time on the compressor and the condenser fan motor by up to 75% thereby extending the compressor's and fan motor's life, reducing downtime and energy costs.window ac unit filling with water Three model lines of ComPac wall mount air conditioners are built - the HVEA line, the AVPAcover window ac unit in winter line and the AVPC line. split unit ac unitsThe HVEA line is our most efficient units with EER's (Energy Efficiency Ratio) up to 11.70 and feature an electronically commutated outdoor fan motor. The 3, 3.5, 4 & 5 ton HVEA models are available with a 2-stage compressor.

cooling is approximately 65% of the total cooling capacity. The 2-stage compressor provides lower start-up amps which can be critical when operating with a generator. compressor also reduces energy costs and is able to more precisely match the cooling capacity of the air conditioner with the heat load in the shelter. The AVPA units are our most popular units and have EER's that range from 9.00 to 10.20. The ComPac I and ComPac II are built in cooling capacities of 1, 2, 2.5, 3, 3.5, 4, 5 and 6 tons and for operation on a variety of power supplies. Units are tested to Underwriters Laboratories and CAN/CSA standards, listed by ETL, and rated for performance and efficiency according to the ANSI/Air Conditioning and Refrigeration Institute Efficiency Standard 390. Our newest line of air conditioners are the ASDCA/HSDCA models. These models feature a "full flow economizer", a 48 VDC indoor air mover and the CoolLinks controller. The full flow economizer provides the same quantity of outside air as the unit

does in mechanical cooling. The 48 VDC air mover allows the shelter to be ventilated/cooled in the event of a loss ofThe CoolLinks controller sequences the operation of two air conditioners to ensure the most efficient conditioning of the space and the most balanced use of HVAC units. The CoolLinks controller has eight HVAC alarms andAn Ethernet connection is also provided for a SNMP interface through which the Network Operations Center can receive traps (alarms), monitor/change cooling and heating set points, and monitor HVAC unit and system Marvair offers a variety of thermostat/controllers specifically designed to control two or more air conditioners in a telecommunications shelter. Go to our Telecom Controllers page for an overview of our various thermostats/controllers. Numerous options are available to meet special requirements. (Please see the Product Data Sheets for a complete listing and description of the options). Dehumidification Field or factory installed controls allow humidity to be maintained at or below a specified humidity set point.

These units do not have the ability to add humidity to the building. Coastal Environmental Package - recommended for units installed near the ocean. External Low Noise Blower - used to reduce the sound of the unit in urban installations. Cabinet color and material. The units are available in several colors and can be constructed of aluminum or stainless steel. Hot Gas Bypass - Factory installed refrigeration controls permit near continuous operation of the compressor. Used in specialty structures, e.g. magnetic resonance imaging (MRI) and television broadcast buildings to eliminate voltage spikes caused by the compressor starting and stopping. ASK THE EXPERTS: Cooling & InsulationNow that summer is in full swing, air conditioners are a necessity — and one YouTuber is showing the world how to build one that operates using solar energy for under $50. A video from YouTuber desertsun02, a DIY solar power projects channel, is making the rounds on Facebook this morning and has been viewed nearly 3

million times, first spotted on In the video, desertsun02 shows viewers how to make a home-made AC Air Cooling unit that can get the air as cold as 42 degrees Fahrenheit using only a PVC pipe, small fan, cooler, and The entire project would easily cost less than $50 according to our own estimates — not including the power tools that to cut holes in the top of the cooler — and would take roughly 15 First, desertsun02 made two holes in the top of the cooler with aHe measured the holes to fit the PVC pipe as well as a He then filled the cooler with ice — he recommended using two big jugs of frozen water so when they melt, there’s no clean up involved — and positioned the fan facing down towards the ice. Here's the final result: The fan was connected to a battery pack that desertsun02 said would last seven hours with the ice melting after roughly fiveIt could also be solar-powered. Though it may not look pretty, the entire project would
