Steam hot water type surface air cooler cold water copper tube radiator stainless steel air heater dry coil

As a manufacturer, we have been engaged in the production and supply of air radiators and other related products for many years. We know that no matter what products are used before, they need to be installed first. For the application of air radiators, there is no exception. In order to further promote users 'understanding of them, our company's staff members need to install their air radiators as follows:

 1. First, open the packaging of the air radiator, install the vent valve and the movable joint;

 2. Secondly, put the expansion pipe in and lay it flat;

 3. Use percussion drill to drill hole 12, its depth is calculated after the expansion pipe is put in, and then its outside is flush with the wall.

 4, then install the bottom hook, to meet certain requirements, tighten the screws;

 5, and then put the inverter air radiator on the bottom has been installed on the hook, in the upper installation hook to adjust the position of the hook, to be tightened, you can tighten the expansion screw, in the placement of the radiator when the vent valve should be placed in the upper position;

 6. Install the pipe joint again. Install the pipe according to the requirements of the drawing and connect it with the inlet and outlet. Tighten all parts. The rear side is 87.5px away from the wall and should be about 125px away from the kick line.

 7, * After the input of hot water, open the vent valve, vent until the water. Air radiator in operation remember not to exceed the operating pressure listed in the manual.

Product Name: Surface cooler

Details:

The fins of the cooler are double-folded louvers, which ensure the interference of air heat exchange and make it in a flowing state, greatly improving the cooling and heating efficiency. There are three strict cleaning procedures at the factory for the aluminum fins of the surfacer. Metal cleaning agent, ultrasonic cleaning agent, clean with water, ensure that there is no residue on the fins, so that the air flow is more smooth, fundamentally ensure the reliability of heat transfer.

The surface cooler radiates heat to the refrigerant and outdoors. The compressor compresses and discharges the gas inside the body into a low temperature and high pressure liquid. Refrigerant is used to absorb heat from surface coolers, steam hot water type surface coolers cold water copper pipe radiators stainless steel air heaters dry coils gradually reduce the temperature of the cooling space. The surface cooler cools the air outside the fins by the flow of internal refrigerant water, and then transports it to the place of use. The unit surface cooler refrigerant water absorbs heat and brings it back to the main engine, releases cooling water and heat, and then flows into the surface cooler to absorb heat for cooling. Air, continuous circulation.

TL type high efficiency heat exchanger copper tube through aluminum sheet, mechanical expansion tube so that copper tube and aluminum sheet close contact. Arc ripple can increase fluid velocity, destroy boundary layer and raise heat transfer coefficient. Excellent structure, reasonable design of plate and tube spacing combined with water stroke, make the heat exchanger have good heat transfer, small air resistance, compact structure and light weight. In air conditioning, refrigeration, dehumidification, heating and other steam hot water surface cooler cold water copper pipe radiator stainless steel air heater dry coil engineering widely used. Surface coolers can also be connected to air ducts as a cooling or heating unit. Copper tube brazing, to ensure that the pressure is greater than 1.2Mpa. Surface coolers are available in a variety of blade pitches (2.2-3.5 mm).

I: Main specifications are:

II: TL type numbering method is:

Example TL× 4× 24× 1500(Z)2.7
TL———— model
4———— rows N
24———— Number of surface tubes n
1500———— Surface pipe length A
(Z)——Air flow direction left (Y is right)
2.7 sheet———— spacing t=2.7
Related technical parameters:
Windward area: Fy=A× B(m2) Heat transfer area: F=Fd· A· n· N(m2)
Heat dissipation area per meter: Fd=0.84m2(sheet pitch 2.7) Total water area: f=1.767× 0.0001· n(m2)
Ventilation net area ratio: =Ff/Fy=0.532(calculated by sheet spacing 2.7).

III: Selection of surface cooler materials and types

1: Copper tube series aluminum foil surface cooler

2: Stainless steel tube series aluminum foil surface cooler

3: Copper tube series copper foil surface cooler

4: stainless steel tube series stainless steel fin surface cooler

5: Serpentine coil type: fan coil type, flat-plate type air conditioning unit, flowing medium can be cold water, hot water.

6: type of air cooler: air-cooled heat pump unit, constant temperature and humidity unit, air cooler, l type, u type, v type, w type, flowing medium is mostly fluorine or 407 environmental refrigerant.

The difference between evaporator and surface cooler

The medium entering the surface cooler is usually hot water and cold or brine.

The medium entering the evaporator is refrigerant refrigerant such as R22, 410, 407.
