Preferably, the compressor frequency-changeable compressor or the compressor unit parallel with one another for more than two, from
And realize that the capacity of compressor can be adjusted.
Below to the embodiment of the present invention in the operation principle of Teat pump boiler be described in detail：
(1) as one or less people's hot water or water consumption less (low discharge water inlet i.e. caused by low discharge water outlet),
Half gallbladder pattern is may be selected, and now a compressor list is only opened in frequency-changeable compressor low-frequency operation or two compressor units
Unit, as the capacity of compressor is little, the aerofluxuss of compressor are flow through from the first condenser 220 automatically, and due to second cold
The circulation area of condenser 230 is little, self resistance is big, adds the reason that bending pipe 231 has lubricating oil, therefore the second condenser 230
Flow through without coolant, which achieves the top half gallbladder heating of a feed-tank 210, in the case where guaranteeing that hot water meets use,
Many remaining hot waters thermal loss in water tank 210 is reduced as far as possible.
(2) as many people or when needing Large Copacity hot water, full gallbladder pattern may be selected, i.e., now whole box water is carried out plus
Heat, now frequency converter sets high frequency operation or two compressor units are opened simultaneously, as the capacity of compressor is big, are compressed
Device is flow through from the first condenser 220 and the second condenser 230 automatically, which achieves the FCL heating of water tank 210, it is ensured that heat
Water meets use.
As can be seen here, by Teat pump boiler provided by the present invention, the demand of difference water number is met, reduces heat
Can waste, energy-conserving and environment-protective, and shorten the waiting time again with hot water.
