In the climate control (Fig. 9.46) is used as a refrigerant fluid R134a. Capacity of the system is (650 ?� 50), the units used for lubrication oil Nissan Model R (KLHOO-PAGPO). The amount of oil in the installation 200 cm3. When replacing individual aircon units must replenish the amount of oil; so the replacement compressor add 200 cm3, condensate-ra - 75 cm3 of the evaporator - 75 cm3, drier - 5 cm3 of the pipeline - 30 cm3. Characteristics of the air conditioning compressor are shown in Table. 9.2. Drive kompres-litter carried by a belt from the crankshaft pulley. On models with petrol engine drive belt ribbed on models with diesel engine - wedge. Tension belts made idler pulley. By clicking on the branch of a belt deflection force of 98 N shall be, mm: - Engine GA14DE - 5-7 for a new belt 6-8 for operating the belt; - Engine GA16DE - 5,5-6,5 for a new belt 6-7 for operating the belt; - The engine of CD20 - 9-11 for a new belt, a belt for working 11-13. Technical characteristics of the air conditioning compressor are in tabl.9.2.
