Cooling system термостатируемая, an elevated pressure

The pump of a cooling liquid centrifugal, the thermostat with extending working body. After warming up of the engine to normal working temperature the thermostat opens, therefore the liquid arrives in a radiator in which it is cooled and again the engine arrives. The cooling system is connected with atmosphere a radiator stopper in which there is a control valve. Such design provides increase of a boiling point of a liquid and efficiency of cooling of a liquid in a radiator. If pressure in cooling system exceeds level at which works подпружиненный the control valve of a stopper of a radiator under the influence of pressure the valve rises from a saddle and the liquid part flows through перепускную a pipe in an additional broad tank with a cooling liquid. At cooling of system surplus of a liquid flows down back in a radiator.

The tank, supports liquid level in system and simultaneously is the tank for reception перегретой liquids. The system of cooling of this kind is called as closed as the liquid following through the valve of a stopper, remains for the further use.

Heating system

The heating system includes the fan and a radiator mounted in the uniform case under the right part of the forward panel of a body, hoses of a supply and tap of a cooling liquid from system of cooling of the engine and the control panel heating / by air cooling in the salon, deduced on the forward panel of a body. Нагретая from the engine the cooling liquid proceeds through a heater radiator. The heating mode is set by opening заслонки therefore the heater case is informed with salon space. The switch on the control panel provides management of work of the fan which forces air stream through a radiator.

Air central air

The central air consists of the condenser mounted before a radiator, the evaporator established near to a radiator of a heater, the compressor mounted on the engine, влагоотделителя with редукционным the valve of a high pressure, hoses and the pipelines connecting all specified units.

The fan directs a stream of air from salon on an evaporator radiator on which there is a return of heat from air to a coolant. In a radiator of the evaporator of a coolant boils with a production of steam of low pressure, providing and heat selection. The compressor provides circulation нагретого a coolant, keeping its elevated pressure, from the evaporator in the condenser where there is a coolant cooling, and back in the evaporator.
