4. Systems of cooling, heating
The heater block, the block of the fan and the conditioner, the bodies mounted under the forward panel
On the cars considered in the real Management, the compulsory termostatiruyemy system of cooling of an elevated pressure (see fig. is established. Device of system of cooling).
Liquid circulation in the engine is provided with the centrifugal pump mounted in a forward part of the block of cylinders. Liquid flows round cylinders and goes to a back part of the engine. Further liquid proceeds in the cast channels of soaking-up and final collectors, in cavities about spark plugs and directing plugs of final valves.
The thermostat with an extending (paraffin) working body is mounted near transmission and closed by a cover. At an engine warming up the thermostat is closed and cuts a liquid stream from a radiator. After engine warming up to normal working temperature the thermostat opens, therefore liquid arrives in a radiator in which liquid is cooled and again the engine arrives.
The system of cooling is connected with the atmosphere a radiator stopper in which there is a control valve. Such design provides increase of a boiling point of liquid and efficiency of cooling of liquid in a radiator. If pressure in system of cooling exceeds level at which works the podpruzhinenny control valve of a stopper of a radiator, under the influence of pressure the valve rises from a saddle and the part of liquid flows through a perepuskny pipe in an additional broad tank with cooling liquid. When cooling system excess of liquid flows down back in a radiator.
The tank thus, supports liquid level in system and at the same time is the tank for reception of peregrety liquid.
The system of cooling of this kind is called as closed as the liquid following through the valve of a stopper, remains for further use.
The system of heating 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 removal of cooling liquid from system of cooling of the engine and the control panel air heating/cooling in the salon, deduced on the forward panel of a body (see fig. The heater block, the block of the fan and the conditioner, the bodies mounted under the forward panel). The cooling liquid heated up from the engine proceeds through a heater radiator. The mode of heating is set by zaslonka opening therefore the case of a heater is reported with salon space. The switch on the control panel provides management of operation of the fan which blows in a radiator therefore there is an air heating.
Air central air
Central air consists of the condenser mounted before a radiator, the evaporator established near a radiator of a heater, the compressor mounted on the engine, a moisture separator with the reduktsionny valve of a high pressure, hoses and the pipelines connecting all specified units.
The fan directs an air stream from salon on an evaporator radiator on which there is heat return from air to a coolant. In a radiator of the evaporator there is a coolant boiling up to production of steam of low pressure and heat selection in process of steam removal from a radiator. The compressor provides circulation of a warm coolant, keeping its elevated pressure, from the evaporator in the condenser where there is a coolant cooling, and back in the evaporator.
