REMOTE SYSTEMS

The charge in the lines of communication it is important to have the right size line installation. Metering control of refrigerant in the system is carried out by the exact dimensions (diameter and length) liquid line. This line should be used as delivered. It cannot be reduced.

Lennox has refrigerant flow-control (RFC) system. This is a very accurate means of accounting refrigerant in the system. It should never be used during the installation process. The whole principle RFC system involves the comparison of the evaporator to the proper length and diameter of the liquid line. This, according to the manufacturer, exceeded the capillary tube systems. RFC aligns pressure almost immediately after stopping the compressor. So he starts unloaded, eliminating the need for any additional controls. In addition, the exact quantity of refrigerant in the system is added at the plant, resulting in its uninterrupted work.

The condensing unit comes with the full amount of the refrigerant. In the condenser and the evaporator have flared liquid and suction lines for quick communication. Compressor hermetically sealed. The unit can be built in from the weather and, as a tough part of the building structure. (See Fig. 5.10.) In the compressor can be free-standing on the roofs of houses or plate at zero.

Fig. 5.11 shows a condensing unit, intended for apartments the developer and the amount of builder. It comes in 1-and 1.5-and 2-ton sizes. Cooling capacities range from 17,000 through 28,000 BTUs. Aluminum grille protects the condenser, offering low air resistance. The fan is less noise. It also reduces the probability of recirculated air through the condenser, where it is closely banked for several installations. When installing on a zero, it will help the hot air from harmful grass and shrubs.
