Product Description
Shell tube type water cooled evaporator is suitable for water
cooled unit, water source heat pump, air cooled pump and air cooled
heat pump unit. The product is applying for refrigerants of R22,
R134a, R407C and R410A etc. The referigerating medium is for tap
water, underground water, river water and sea water or brine, water
and glycol solution, sulfate solution, etc. For heat exchange tube,
copper pipe, copper nickel alloy tube, aluminum brass tube,
stainless steel tube, etc. The shell raw material mainly are
seamless steel tube, stainless steel pipe.
1, Heat exchange tube: four main tube type.
(1) ∅ within 3/8 "thread copper coil, it is mainly used for" U
"type tube evaporator.
(2) ∅ within 1/2 "threaded straight copper tube, straight tube is
mainly used for dry-type evaporator.
(3) ∅ 1/2 "corrugated straight stainless steel tube, straight tube
is mainly used in food industry of dry evaporator.
(4) ∅ 5/8 "inside outside screw wing efficient copper tube, it is
mainly used for air precooling industry dry evaporator.
2, shell raw material:
There are two of the major materials:
(1) # 20 seamless steel tube, mainly used for all kinds of load -
more than 20 ℃ cold agent.
(2) 304/316 l stainless steel tube, it is mainly used for food and
low temperature (below 25 ℃, higher than 40 ℃) of the refrigerant,
316 l can also be used for cooling load of the sulfate for
industry.
3, interface:
(1) load cooling interface main type of flange, thread and clamp
type, as shown in figure. According to the demand of users.
(2) the refrigerant interface are mainly brass brazing type, loose
flange connection type and tenon surface flange connection type,
etc. As shown in figure. Can meet the requirements of users and
habits to the greatest extent.
(3) the upper shell put empty set, lower set drainage outlet.
Nozzle temperature is set on the mouth. Also can according to user
requirements including water flow switch interface, antifreeze
switch interface. Temperature measurement are mainly female mouth
mouth and various rules of blind brass like ∅ 5/16, "3/8", 1/2 "∅
∅, ∅ 5/8" brass or stainless steel tube, etc.

4, refrigerant gateway layout:
In and out of the refrigerant from the evaporator end, also can
from both in and out of, convenient customer cloth tube.
5, refrigerant flow design.
Refrigerant can be designed into two processes, three processes and
four processes. Can effectively guarantee the length of
evaporation.
6, the length of the evaporator design.
Adjustments can be made according to the length of the condenser,
evaporator length to ensure two configuration after the appearance
is beautiful and satisfies the customer the installation space.
7, "U" type oil return pipe evaporator effect is good
The holes are gathering technology after make so the heat exchange
efficiency is improved greatly. Under the condition of same
refrigerating capacity, compared with the straight tube can greatly
reduce the size of our evaporator, reduce the purchasing cost.
8, "U" type tube evaporator core body can be pulled out, convenient
cleaning and maintenance.
9, the structure of the double "U" evaporator and the compressor
straight tube can be symmetric arrangement
The advantages of convenient take over and appearance is beautiful,
but the purchase cost increase.
In addition
The ordinary evaporator has rich experience in design and
manufacture, for special evaporator, such as the food industry,
industrial sulfuric acid, corrosion, acid and alkali resistance,
salt tolerance) and low temperature series can also be designed and
manufactured according to customer requirement. The normal
operation of the above several evaporator were successful in all
parts of the country.
Please pay special attention to customers:
1, biggest water flow and water flow is not greater than 1,
otherwise it will affect the service life.
2, according to the annotation contributes presents installed
correctly in and out of the gate, otherwise it will affect the
effect and service life.
The shell side of the pressure design: normally design pressure is
1.0MPa, tube side design pressure is 1.5MPa. Heat pump tube side
design pressure is 2.4 MPa. If you have special request, please
contact technical department.
