Product information

It adopts an internationally-know↔☆÷ n brand full-closed scroll compressΩ∏or,and the evaporator copper tub¶™'♣e adopts internal and exter£☆®nal screw-type reinforcing ‌> tubes.The surface of the copper pipe is↕λ threaded,the outer surface of the co≤∏pper pipe is smooth,the cooling e±∏™ffect is good,no condensati↕α©$on occurs,and the loss o>←∞>f the cooling capacity is smal Th β$e condenser is process✘‍ ed into a trapezoidal low-ribbe"↕×d tube,which enhances the h×↕≥eat transfer capacity.The surface of♦™ the copper tube is smooth,s≈♦σo that the water pressure is r→™δ educed,andit is easy to clean and ✔£maintain.Protection syste↕Ωm devices include:compr'↓essor delay start protector,Ω©∏☆overload protector,h₹÷igh and low voltage pr↓←otector,temperature controlδ  switch,etc.to ensure the normal operat$×βion of the unit.

1、 Definition an≠®±d working principle of water-cooled ¥&©™Chiler

A water-cooled chiller is a α®≈type of refrigeration machine that di¶∏ssipates heat through a water-cool↔→®☆ed condenser, using a ref¥♥™rigerant circulation system (compre≠≤≥ssor, evaporator, cond↓ ♠↓enser, expansion valve) to tra™€nsfer heat to the cooling water, ther₹πeby providing low temperature c♠®₩hilled water for industrial or com≈$✔↔mercial systems. Its core advantage®♦•s are high energy ef•∑£✘ficiency and stable operation, w↑>¶₽hich is suitable for high-loa"& ∞d and continuous operation φ‌©σscenarios.

2、Core components and workflow

Compressor:

Type: Screw type, centrifugal &₩type, scroll type (select‌♦"π according to cooling demandΩ♥÷¥).

Function: Compress refriger≥σant (such as R134a, R410a) to dri®γ€ve the refrigeration cycleλ£φγ.

Evaporator:

Shell and tube heat exchanger>ε§ or plate heat exchanger, the '♠₩refrigerant absorbs thπΩσδe heat of frozen water an→©♣d evaporates.

Condenser:

Water-cooled design, through cooling ♠←∏ water (such as cooling tower circα±<≤ulating water) to taε ke away the refrigerant heat.γβ

Expansion valve:

Adjust refrigerant f≤≠low and control evaporator inlet press©≈ure.

Water pump and cooling ←σ¶©tower:

Drive the cooling water circulation, t✘ ±₩hrough the cooling tower €π×≈to dissipate heat to t> he atmosphere.

Working process：

The refrigerant absorbs the heat of t±®↔he frozen water in the ÷∏​evaporator and converts §↔> it into a low-temperature gasΩ÷.

Compressors compress low tempera㶮∏ture gas into high temperature ♥™↓and high pressure gas.

The high-temperature gas is÷ε dissipated by cooling water in the β↓condenser and condensed into a high-pre♦→₽→ssure liquid.

After the expansion valve depresses,←✔ the refrigerant re-enters γ‍Ωαthe evaporator circulation.

6、 Selection suggestions

Cooling capacity calcu₽♠lation:

According to the equip ♣ment heat (Q= power x efficie≠↔↔✔ncy) and ambient tem​≈​perature, choose a redundan"₽δ♣cy of 20%-30% models.

Cooling water system ¶×ε↕matching:

The cooling tower capacity shoulεσ≥<d match the cooling de​₽¥mand of the chillersα←≥ (cooling water flow ≥ the rating₹δ♣₽ of the chillers).

Function extension:

Frequency conversion co€'¥πntrol: Continuous opλ™eration scenarios wi γγ≠th high energy saving ÷↑"βrequirements.

Explosion-proof design¥≈≥: chemical industry, oil an∏ ✘δd gas industry.

7、 Maintenance and maintenance po ×ints

Daily maintenance:

Check the water quality ↔α‌(pH value, hardness) of the cooling wa★→ter every month to prev×♣÷×ent scale from blocking &‌≤the condenser.

Clean condenser lines (chemical cleaπ<≠ning or mechanical scrλ'ubbing).

Quarterly maintenancε≠e:

Check the refrigerant pressu"∑¥÷re and lubricating oil sta‍×λtus, and replace or rep≠±lace the refrigerant in ✔←time.

Calibrate temperature sensors and pre↔πσ™ssure switches.

Annual maintenance:

Comprehensive inspection of comp• ♥×ressor, pump and valve tightness.

8、 Summary
