| Sanitary Hot Water SHW 30 |
|
|
|
The CARBOROBOT boilers capable to heat sanitary hot
water(SHW) with separate hot exchanger. The hot exchanger placed
direct on the side of the boiler. This hot exchanger work only close
of the boiler body, with distance from the boiler it is not work.
The hot exchanger have input for the cold pipe water and output
for the hot water, what we can use direct or for the buffer of hot
water. If we open the hot water tap the cold pipe water will flow
in the hot exchanger and the sensor will start the pump of hot exchanger.
This pump will run until the tap is open. When the tap we close,
the sensor will switch off the pump after some minutes(when the
input tube will grow hot from the boiler).
The special feature of this equipment when the boiler body is cold
the sensor will switch on the pump at that time also when the tap
of hot water is closed. The pump will run until the boiler temperature
will higher then switch off temperature of hot exchanger sensor.
This temperature adjustable in the box of hot exchanger. It is expedient
to regulate around 40°C to avoid the unwanted work of the pump.
If we use this type of hot exchanger than the regulation of the
boiler need to make depend to the water temperature of the boiler.
It's mean the regulation of the boiler not with the room thermostat,
(in this case the boiler can be regulary cool down bellow than 40°C).
The hot water reserve in the boiler is big. One Farmer 40kW boiler
with the heating water inside more than 1000kg. This hot mass can
serve several hundred litre 50-60°C DHW in a short time. The boiler
after falling of temperature of the heating water app. 10°C will
start automatically and the SHW source. In the practice one powerful
shower and one SHW tap in one time can operate. The hot exchanger
module can be dismounted for the cleaning. The cleaning period depend
to application time and the water hardness. We recommend to use
lime prevention systems. This hot exchanger unit separate can be
buy and possible to use for any CARBOROBOT boiler.
Heat capacity app. 30kW/h
Delta t. 40°C (60°C boiler temperature and 10°C pipe water temperature)
Flow through 12litre/min if water pipe pressure is 3 bar

Buffer accumlator
|
|
|
If we using firewood chamber frequently(more
hours every day )than for the CARBOROBOT Farmer need the
buffer accumlator.
If we usning firewood chamber only infrequent(1-2 hour
time on the week) than not necessary to use buffer accumulator.
For the CARBOROBOT types not necessary
install buffer accumlator, but if we build compose system with
solar than it is important part..

Brazed plate heat exchanger
|
 |
|
The Brazed Plate heat exchanger consists of either
25 or 50 multiple, thin, slightly-separated corrugated plates
that together form a very large relative surface area given the
volume of these heat exchangers.
The Outstanding Features:
Compact structure and easy installation
Light in weight
Small consumption of water
Outstanding Overall Heat Transfer Coefficient
Wide Variety of plate sizes and Patterns
Durability and
Stainless Steel
Low scaling coefficient

Plate heat exchanger
|
 |
|
|
Another type of heat exchanger is the plate heat exchanger. One
is composed of multiple, thin, slightly-separated plates that have
very large surface areas and fluid flow passages for heat transfer.
This stacked-plate arrangement can be more effective, in a given
space, than the shell and tube heat exchanger. Advances in gasket
and brazing technology have made the plate-type heat exchanger increasingly
practical. In HVAC applications, large heat exchangers of this type
are called plate-and-frame; when used in open loops, these heat
exchangers are normally of the gasketed type to allow periodic disassembly,
cleaning, and inspection. There are many types of permanently-bonded
plate heat exchangers, such as dip-brazed and vacuum-brazed plate
varieties, and they are often specified for closed-loop applications
such as refrigeration. Plate heat exchangers also differ in the
types of plates that are used, and in the configurations of those
plates. Some plates may be stamped with "chevron" or other
patterns, where others may have machined fins and/or grooves.
