His­pa­cold – to­tal ef­fi­ciency

ABC (Australia) - - SUPPLY LINES -

... the flex­i­bil­ity it needs for com­ply­ing with the re­quire­ments of ev­ery end user

IF THE NAME His­pa­cold sounds fa­mil­iar to you it might be its strong 40-odd year con­nec­tion to a lead­ing Span­ish brand of com­mer­cial ve­hi­cles, but you’ll be pleased to know its air-con­di­tion­ing prod­ucts are suit­able to a full range of other bus and coach brands in the Aus­tralasian mar­ket­place.

With more than 50 coun­tries around the world hav­ing ex­pe­ri­enced the ef­fi­ciency of His­pa­cold’s sys­tems and its adapt­abil­ity to the most ex­treme at­mo­spheric con­di­tions, the obli­ga­tions it has ac­quired due to the high vol­ume of ex­port of prod­ucts means His­pa­cold is obliged to ex­tend its ser­vice guar­an­tee to the same de­gree, the com­pany states.

His­pa­cold main­tains di­rect con­tact with ev­ery one of the points which make up its world­wide ser­vice net­work, it says. Through tech­ni­cal train­ing cour­ses, spe­cific man­u­als and a pre­cise un­der­stand­ing of each client’s needs, His­pa­cold guar­an­tees the to­tal ef­fi­ciency of any of its tech­ni­cal as­sis­tance ser­vice points.

The com­pany also en­sures that each client has the most con­ve­niently lo­cated ser­vice point, wher­ever they are on the planet, it’s claimed. Its ac­tual ex­tended ser­vice net­work in more than 100 coun­tries as­sures our cus­tomers the best after-sales ser­vice, says His­pa­cold. Some of the main points to con­sider are:

• It sup­plies elec­tric HVAC units and has been sup­ply­ing th­ese for sev­eral body­builders in Europe since 2010;

• It has de­vel­oped dif­fer­ent con­fig­u­ra­tions, so it can eas­ily sup­ply air- con prod­uct for most bus sizes and con­fig­u­ra­tions: rigid, ar­tic­u­lated, and dou­ble ar­tic­u­lated.

No­tably, His­pa­cold has sup­plied units for projects in sev­eral coun­tries in sev­eral ma­jor cities, such as Spain (Madrid, Barcelona, Va­len­cia), France (Mar­seille, Metz), UK (London), Italy (Parma), and Lux­em­bourg, prov­ing it has a great record with elec­tric projects, it states.

With some of th­ese cities, mainly in the south of Europe, hav­ing hot sum­mers, His­pa­cold says it has de­vel­oped more pow­er­ful units with dou­ble cool­ing cir­cuits.

Con­versely, for colder coun­tries it has de­vel­oped heat pump sys­tems, with ad­di­tional heat­ing sys­tems for very low tem­per­a­tures. If there is wa­ter avail­able from the chas­sis to be used for the heat­ing, His­pa­cold can use it. If there is no wa­ter avail­able, it has con­fig­u­ra­tions so that the HVAC sys­tems can still do the job, the com­pany says.

IN­TER­NAL KNOW-HOW

It is in­ter­est­ing to note that elec­tron­ics and soft­ware used on His­pa­cold air- con­di­tion­ing ap­pli­ca­tions are de­vel­oped in-house.

The rea­son for this, says the com­pany, is to give His­pa­cold the flex­i­bil­ity it needs for com­ply­ing with the re­quire­ments of ev­ery end user.

Some of its clients want the HVAC unit to man­age the tem­per­a­ture like a con­ven­tional unit. Some oth­ers pre­fer to work with a delta against out­side tem­per­a­ture. Ei­ther way, His­pa­cold

says it can adapt the per­for­mance of its units to any of th­ese re­quire­ments, in­clud­ing com­mu­ni­ca­tion with the pow­er­train for op­ti­mis­ing battery state of charge.

BTMS UNITS

His­pa­cold also de­vel­ops and sup­plies Battery Ther­mal Man­age­ment Sys­tem units. Th­ese in­clude a new range of rooftop units for con­ven­tional (diesel, CNG) buses, which is to be launched dur­ing the first half of 2019.

High­lights of th­ese in­clude: low­est weight in its class; low­est re­frig­er­ant charge in its class; and suit­able for ‘tran­si­tion re­frig­er­ants’.

In terms of the lat­ter, it should be noted that en­vi­ron­men­tal reg­u­la­tions are en­cour­ag­ing the in­dus­try to move to lower Global Warm­ing Po­ten­tial (GWP) re­frig­er­ants. That is, R134a is the most com­monly used gas for HVAC units. Avail­abil­ity of this gas is be­ing re­duced. This is the cur­rent sit­u­a­tion in Europe, although most of the coun­tries have sim­i­lar reg­u­la­tions.

It is ex­pectable that in some years it will be dif­fi­cult to get sources of R134a. Although maybe to­day this is not an im­por­tant is­sue yet, con­sid­er­ing the usual life­span of the city buses in Aus­tralia, most of the fleets will have to face this sit­u­a­tion in some years, says His­pa­cold.

Now while there is un­cer­tainty in the in­dus­try about fu­ture al­ter­na­tives for re­frig­er­ant gases, one pos­si­ble tran­si­tion re­frig­er­ant is R513A. His­pa­cold says it is de­vel­op­ing its prod­uct range for be­ing able to use this gas in fu­ture with mi­nor changes in the units.
