42 Liber 13 “W x 19” H x 13 “D so that the ground pressure meets the limits of aircraft production.

• • Voltage: V12 / V24
  • Output: CFM200 – spins about 4 times all the air in the cabin every 60 seconds for a 4-seater aircraft.
  • Cooling output: 5000 – 7000 BTU
  • Current consumption: 19 – 27 amps

 

The air conditioning unit is designed for work with varying output depending on the power consumption that the alternator will provide
If the aircraft provides a current of about 19 amps, the unit will provide a minimum output of about 5000 BTU
If the aircraft provides a current of about 27 amps, the unit will provide an output of about 7000BTU
The air conditioner starts working at low output to prevent a relatively high starting current.

• • General weight meets the limits of the aircraft trunk and will be taken into account in weighing the aircraft and calculating the torque C.G.

 

• Rom will fix the air conditioner to the floor of the trunk to the original mooring points of the aircraft, in addition to drainage to condensed water and a side opening for condensing air emission by flexible air roll provided by the manufacturer

The air conditioning outside the plane to the atmosphere.

Screw compressors

A compressor is basically a type of pump that pumps gas, and when it does – compresses it. The purpose of the compressor is to increase the pressure of different gases by reducing and reducing their volume. Compressors are used for various medical, domestic and industrial needs. Buying an air compressor is not a common or everyday occurrence. This is an important purchase and usually relatively high cost, so it is advisable to check the relevant tests and turn to an experienced and reputable company that specializes in the production of compressors – also called compressors.

& nbsp;

How does it actually work? First it should be noted that during the operation of the compressor a high pressure is created which causes it to overheat. It is necessary to cool the compressor as otherwise it will be damaged. Therefore about a third of the volume of the compressors contains the masking oil and cools the body of the compressor and its motor. In compressors designed for home cooling, the gas moves in a closed-circuit piping system. From the compressor – the gas comes out in compression at a high temperature (above 120 degrees), passes through an evaporator where the temperature drops (about 50 degrees) and is returned to the compressor by suction in pipes. The result is that the gas cools and from there it is returned to the evaporator.

& nbsp;

The different types of compressors of course have different and varied uses, so the first step before buying a compressor is its uniqueness and delineation of its purpose – what tasks and what purposes is the compressor intended to fulfill? Compressors have different and varied volumes. There are industrial compressors as opposed to compressors designed for a person’s private use. Therefore, the questions that the professional should ask are first and foremost for what use is the compressor intended and for what scope of activity – private or industrial?

& nbsp;

For example, a piston compressor – intended for industrial use. Piston compressors are not intended for pharmaceutical or food industries. On the other hand, a dry compressor does not contain lubrication which is actually intended for bodies such as laboratories, dental clinics, food industries and more. In this compressor – the oil does not pass to the air line or to the container, so the air remains dry. Screw compressors are compressors that handle large amounts of air. These are small compressors relative to their air supply, and these are designed for industrial needs. They have an electronic monitor and even a controller that indicates the hours of work of the compressor and the elements that need to be replaced during treatment.

Energy saving

Dunham Bush, a leader in industrial refrigeration for over 100 years, has developed an advanced method of cold storage. This method is an ancient method that has revolutionized the world of green energy today. Today, the method is considered one of the most effective methods for significant savings in electricity consumption.

 

The cells in the system toil in freezing the ice cells during the night, while the cost of electricity is low. In this way, a large refrigeration unit works throughout the day – only one unit. Chiller units are excellent units for working at night because they do not consume particularly high energy. The refrigeration units operate more easily at night and cool much more efficiently than during load and heat.

 

 

Consumption at night = one-sixth of consumption during the day! This is a significant saving from the many in which the facility is operated!

 

The cooling water is cooled to a temperature of about 5 degrees inside insulated cells in order to prevent waste and loss of water. The water stays at the same temperature even during the day. During the day, the peeling water is used for the main ‘air conditioning and cooling’ cave.

 

Chillers

In a hot country like the State of Israel – one must always think of measures that will help in merging and cooling spaces. However, in light of global warming which is a major problem, as well as the ever-increasing financial outlay on air conditioners of various types – there is today more than ever a need to think about installing alternative cooling systems that will achieve the same result, but with lower environmental impact and maximum energy savings. . We at Dunham Bush offer you a selection of special chillers – quality chiller for cooling and maintaining a reasonable temperature of the water in the air conditioning systems, as well as a chiller for immediate sale to all our customers.

& nbsp;

A chiller system is a closed system that cools the water to a low temperature. This water is transported and circulated through a system of pipes and pumps to all parts of the building and thus they reach every space and room that need air conditioning. There are several types of compressors for chillers and the most common are piston compressors and centrifugal compressors with variable blades. The large tank that occupies most of the area of ​​the chillers is a heat exchanger in whose space the water intended for cooling flows. Inside this large tank are cold gas pipes that cool the water without touching or mixing with it (just as the cold gas does not mix with the air in the home air conditioner). Smaller spaces have a blower unit, and large spaces have air handling units. They can be used to turn the system on or off or even to regulate the temperature (in the case of a hotel, for example). Chiller cooling system is especially designed for hotels, offices, hospitals, clinics and buildings with a high number of spaces that require air conditioning. This is the great advantage of chillers – the fit for buildings with many rooms.

& nbsp;

Advantages of cooling using a chiller system:

& nbsp;

First, it is a compact and space-efficient facility: it is installed internally and does not detract from the aesthetics of the space. The chiller system is known to have a maximum level of reliability and has a very long lifespan – about 15-20 years. In addition, the installation of a chiller system helps maintain the value of the property and is a significant factor in property valuation among realtors and realtors. The system requires almost no maintenance and therefore post-installation expenses are significantly lower than any other air conditioning system. Split or mini central air conditioner.
