HEAT PU MP WATER HEATER COMPRESSOR CRITER I A
PAGE : 5/ 30
COMPRESSOR CR ITERIA
1 St rictl y observe the speci ficati on
Th e compressor should be used in specifications written in this "compressor specification" and
not be used in specifications outside it..
Th e ma in circuit must link up with fuse or breaker.
2 Source voltage
Spec ified in verte r is li nked up with compressor terminals . Applied vo l tage of this in ver te r
should be
vo l tage specified in this "comp re ssor speci f ication" . Al ternating vo l tage sho uld never
be applied on terminals (fo r examp l e: commercial alternating vol tage of l<j>lOOV, 200V, 3<j>200V) . This
i s because
that if app li ed al te rnating current the d irect current motor wi ll demagnetize.
3
Operating vo lta ge ran ge
The compressor
should be operated in the ran ge of rate d vol tage ±10%, under standa rd condition
and overload condition of rate d frequency (app li ed voltage to inverte r ) . It must be satisfied
with item 5 ,6, 7.
4
Operating temperatures and pressures
The operating temperatu r es and pr essures of a compressor sho uld be with in the range shown in
the tab le 2 and g raph 1.
5 Oil Back and height of the oi l level
Oil shoul d be returned continuously to the compressor and not kept in the refrigeration system .
Oil le vel of compressor sho uld be hi gher than 7. 5 mm fr om the lub r icating piece fixed on
the end of the cranksha ft .
Compresso r must not be started ope ra te d under a dual-la yer separate status.
However, in case of foaming si tuation, the height of this foam doe s not mean the height of the oi l le ve l.
If you do not keep the oi l level, the oi l shortage will occur, and influence the r eliability of compressor .
( Plea se check the oil level in the compressor with the sight glass we supply.)

HEAT PU MP WATER HEATER COMPRESSOR CRITERIA
PAGE: 6/ 30
The refrigerating 11E1Chine oil shoold be contirn:JUSly returned to the crnpressor and can not ram.in in the
refrigeratioo systan
Compressor oil surface height should be higher than the fuel supply po1 t 7.5mm or more. Compressor operation, not
allowed to separate the two layers
of oil and refrigeran t. However, when the foam occurs, the liquid becomes foam,
this
pa1 t does no t belong to the oil level.
If you can not meet the oil level, will cause the sliding part of the lack of oil, seriously affecting the reliability.
(Canbe
used to observe the oil witha rniirnr compressor to confum)
There should be supe1heated gas returned to th ecompr essor under all normal operating conditions.

8 Discharge pipe temper at ure
Discharge pipe temper at ure is measured at a di stance 300mm fr om the su rf ace of comp re ssor
and shou ld be less than llo ·c . The tip of the the rm ocouple is fixed by solde ri ng when
measuring di scha rge p ipe temper atu re .Furthermore, solde ri ng point is covered wi th u re thane
foam to p re vent the effect of wi nd .
9 Dust
of compressor hermetic termi nals
Comp re ssor hermet ic te rminals should be mounted wi th spec ifie d cover in ri ght way to prevent
du st entering, and should be used in d irecti on wh ic h dust is hard to enter in.
10 Lead w ire of compressor hermetic termi nals
Measuring the temperature of hermetic te rminal s , lead w ire sho ul d be resist to the temperature
and be clamped so as not in touch wi th the s urfa ce of comp re sso r and pipe .
11 Sta r t - stop fre quency
The
frequency sho uld be less than 6 times per hour. Operating time from start to stop should
be more
than 3 minutes. Stopp in g time should be more than 3minutes.
12 Rate
of r otat ional speed change
The
rate of compressor r otat iona l speed (accele r at ion ) should be less than 133min-'/ s, But if
The var i ab le range is bel ow 120min-', rate can al so be less than 600min-' when r otat ional
speed is reduced to avoid tempor ary over - current .
13 A ir and moisture in refri ger at in g system
The degree of vacuum in refri ge ratin g system sho uld be le ss than 20Pa (1 50X10 -3 mmHg) at
r oom temper atu re j ust befo re cha r ging refri ger ant . The qu ant it y of water shou ld be le ss
than 0. 15ml.
