Industry cold hydraulic engine system composition and principle of work:

The industry cold hydraulic engine is one kind of water cooling equipment, the industry cold hydraulic engine is one kind can provide the constant temperature, the constant flow, the constant pressure cooling water equipment. Cold water mechanic makes the principle is to within the aircraft the water tank pours into the ration the first water, through cold water machine refrigeration system the water cooling, then sends from the water pump the low temperature cooling water the equipment which must cool, after the cold water engine cooling frozen water carries off the quantity of heat, the temperature increment backflow arrives again the water tank, achieves cooling the function. The cooling water temperature may act according to the request automatic control, the long-term use may the economize on water. Therefore, the cold hydraulic engine is one kind of standard energy conservation equipment.

Industry cold hydraulic engine's cooling principle:

The cold hydraulic engine system's operation is through three incident cross-correlation systems: Refrigerant circulatory system, water circulating system, electric appliance autonomous system.

Industry cold hydraulic engine's cooling principle:

The cold hydraulic engine system's operation is through three incident cross-correlation systems: Refrigerant circulatory system, water circulating system, electric appliance autonomous system.

Industry cold water machine-made freezing mixture circulatory system:

In evaporator's liquid state refrigerant absorption water's quantity of heat and starts to evaporate, between the final refrigerant and the water forms certain temperature difference, after the liquid state refrigerant also completely evaporates becomes the gaseous state, by the compressor is inhaled and compresses (pressure and temperature increases), the gaseous state refrigerant (forced-air cooling/water cooling) absorbs the quantity of heat through the condenser, congeals the liquid, (or capillary vessel) reduces expenses after the thermal energy expansion valve turns the low temperature low pressure refrigerant to enter the evaporator, completes the refrigerant cyclic process.

The industry cold water mechanism cold system composes basically:

Compressor: The compressor is in the entire refrigeration system's core part, is also the refrigerant compression source of power. Its function is the electrical energy which inputs transforms as the mechanical energy, compresses the refrigerant.

Condenser: The condenser plays in the refrigeration process is outputting the heat energy and enables the refrigerant the condensation role. The high-pressured superheated vapour which discharges after the refrigeration compressor enters the condenser, it in work process absorption net quantity of heat, including from the evaporator and the refrigeration compressor as well as the quantity of heat which absorbs in the pipeline transmits for the environmental media (water or air) carries off; The refrigerant high pressure superheated vapour congeals the liquid. (according to the cooling medium and coolant conditions' difference, the condenser may divide into three kinds: Water-cooled condenser, forced-air cooling type condenser, evaporative condenser.

Liquid reservoir: The liquid reservoir installs after the condenser, with condenser's bleeder tube is the direct connection. Condenser's refrigerant liquid should open access flows in the liquid reservoir, like this may use condenser's cooling surface fully. On the other hand, when evaporator's heat load change, the refrigerant liquid's required quantity also along with it change, at that time, the liquid reservoir then played fills a prescription with the storing refrigerant role. Regarding the small cold water mechanism cold installment system, often does not install the liquid reservoir, but fills a prescription using the condenser with the storing refrigerant.

Dry filter: Must prevent the moisture content and the contamination in the cold water mechanism cold circulation (greasy dirt, iron filings, copper filings) and so on enters, the moisture content origin is mainly the micro moisture which the new increase's refrigerant and the lubricating oil contain, or, because time overhaul system the air enters the moisture content which brings. If in system's moisture content elimination has been unclean, when refrigerant through throttle valve (thermal energy expansion valve or capillary vessel), because sometimes the pressure and the temperature drop the moisture content can coagulate the ice, causes channel blocking, affects the refrigerating unit the normal operation. Therefore, must install the dry filter in the cold water mechanism cold system.

Thermal energy expansion valve: The thermal energy expansion valve in the cold water mechanism cold system is not only the current capacity regulating valve, is also in refrigeration plant's throttle valve, it installs in the refrigeration plant between the dry filter and the evaporator, its feeling temperature bulb is the wrap in evaporator's exit. Its leading role is causes the high-pressured normal temperature the refrigerant liquid when flows through the thermal energy expansion valve the throttle voltage dropping, becomes the low temperature low pressure refrigerant wet vapor (majority is liquid, small part is steam) enters the evaporator, vaporizes the heat absorption in the evaporator, but achieves the refrigeration temperature decrease the goal.

Evaporator: The evaporator is depends upon the refrigerant liquid the evaporation (in fact is ebullition) absorbs by the cooling medium quantity of heat heat exchange equipment. It is absorbs the quantity of heat in the refrigeration system's function (or name outputs cold quantity). In order to guarantee that the evaporation process can stabilize lasting advance, must unceasing the gas which will evaporate with the refrigeration compressor screen out, maintains certain evaporation pressure.

Refrigerant: The majority industry cold hydraulic engines which uses in the modern industry use R22 or R12 take the refrigerant. The refrigerant is in the refrigeration system's mobile working substance, its leading role carries the quantity of heat, and when change of state realizes the heat absorption and exothermic.

Industry cold hydraulic engine water circulating system:

The water circulating system is extracts the equipment which by the water pump the water from the water tank the user must cool, after the freezing water carries off the quantity of heat, temperature increment, returns to freeze in again the water tank.

Industry cold water mechanical and electrical autonomous system:

Electric appliance autonomous system including power unit and automatic control part.

The power unit is through the contact device, to the compressor, the ventilator, the water pump and so on supplies the power source.

The automatic control part including controls, the pressure protection, the delayer, the relay, the over-load protection and so on inter-combination to achieve the basis water temperature automatic start and the stop warm, protects and so on functions.

Generally the water used cools (i.e. natural water and water tank radiation way two kinds) the way cannot achieve the high accuracy, the high efficiency control temperature goal, because the natural water and the water tank radiate inevitably receive the natural temperature the influence, in the winter the water temperature bottom the water temperature is high in the summer. If temperature in 30℃ the situation, wants the water temperature to achieve 10℃, this is nearly impossible, therefore uses this mode control is extremely unstable.

The industry cold hydraulic engine and the common water used cooling equipment is completely different, because cold water machines and tools have the completely independent refrigeration system, will receive the temperature and the environment influence, the water temperature in 5℃ ~35℃ the scope the regulating control, thus may achieve the high accuracy, the high efficiency control temperature goal. The cold hydraulic engine is equipped with the independent water circulating system, in cold hydraulic engine's water cycle use, but massive economizes on water.
