Cooling and heating systems
The general informationSystem of cooling of the engine
All models of cars considered in the present Management are equipped by system of cooling of the engine working at superfluous pressure with thermostatic management of circulation of a working liquid. The water pump роторного type is fixed on the block of the engine and provides prorolling of a cooling liquid through охладительный a path of the last (details of installation of the water pump see in Section Removal and installation of the water pump). The liquid stream washes areas of an arrangement of each of cylinders in the block then goes to a back part of the engine. Laid in moulding of the block and a head of cylinders охладительные channels provide intensive cooling of inlet and final ports, areas of installation of spark plugs and directing plugs of final valves.
Воскозаполненный the thermostat supervises working temperature of the engine in the course of its warming up. First minutes after start of the cold engine the thermostat remains closed, preventing thereby circulation of a cooling liquid through a radiator. In process of approach of temperature of the engine to normal working value, the thermostat valve gradually opens, connecting to a contour of cooling a radiator providing the maximum intensity of a heat-conducting path from a working body (a cooling liquid).
The cooling system has a tight design and is densely closed by a cover of the radiator, capable to maintain certain superfluous pressure that provides increase of a boiling point of a cooling liquid and, accordingly, efficiency of a heat-conducting path through a radiator. At excess by internal pressure in system of some certain value, подпружиненная the plate of the radiator of a safety valve built in in a cover rises over the saddle, providing an overflowing of surplus of a cooling liquid on connecting (переливной) to a tube in a broad tank. In process of cooling of system the liquid automatically comes back from a tank in a radiator.
Доливание a cooling liquid in system it is made through a mouth of a broad tank (see the Head of Adjustment and routine maintenance) which simultaneously acts also in a role of the receiver accumulating in superseded from radiator surplus of a liquid.
In view of the listed features of a design, such system of cooling has received the name closed as in it any functional losses of a working body are excluded.
The basic components of system of heating of salon are the electric fan and the heat exchanger placed in a box-shaped casing of a heater, fixed under the panel of devices of the car. The heat exchanger by means of rubber hoses is connected to system of cooling of the engine. The block of management is built in by functioning of a heater/conditioner of air in the panel of devices of the car. Разогретая in the engine the cooling liquid circulates through the heater heat exchanger, giving the to air warmly filling a casing. At inclusion of heating of salon there is an opening lamellar заслонки therefore the internal volume of a casing of a heater incorporates to salon volume. At fan inclusion крыльчатка air submitted to salon through the heat exchanger starts to banish the last, providing its intensive warming up.
Air central air
The central air structure includes the condenser established ahead of a radiator close to the heat exchanger of a heater the evaporator, fixed on the block of the engine the compressor, and the filtering receiver-dehumidifier (accumulator) equipped редукционным with the valve of a high pressure. All components are connected among themselves by refrigerator lines.
The fan banishes air arriving in salon through the heat exchanger of the evaporator working in a mode, the return to a mode of functioning of a radiator. The coolant pumped over through the heat exchanger begins to boil and, evaporating, selects at air surplus of heat. The temperature in salon thus decreases to demanded comfortable value (for choice the operator). The compressor supports coolant circulation in system, pumping over разогретую the liquid through the condenser where it is cooled and arrives back in the evaporator.
