Kaori R744 heat exchanger reaches 140bar

Kaori, a Taiwan-based brazed plate heat exchanger technology company, has announced that its patented heat exchanger has reached a critical high-pressure 140bar for CO2 application.

Development of the company's first R744 brazed plate heat exchanger for heat pumps was completed last year.

Kaori develops its own brand-name products, such as Sendzimir mill rolls, brazed plate heat exchangers, high-strength-steel elevated floors and air dryers.

It exports brazed plate heat exchangers to more than 60 countries and holds certifications for ISO, CE, UL and ASME.

The four main components for heating, ventilation and air conditioning (HVAC) machines include the compressor, the condenser, the expander and the evaporator.

Of the four main components, the compressor and the evaporator consume the most space.

In the future, Kaori intends to provide all types of brazed plate heat exchangers for R410A, R717 (ammonia) and R744 (CO2) refrigerants in order to meet stricter regulations and an ever-evolving and increasingly challenging market.

According to the company, it also obtained CG6004 certification in December to show its sound management structure and system.

Kaori products are used in HVAC equipment, industrial equipment and refrigeration systems.

Should home inspectors inspect heat exchangers?

Q. We purchased our home about six months ago. It is only 4 years old, but the heater just failed. The heating contractor found a crack in the heat exchanger. The cost to us for parts not covered by the warranty will be more than $1,000. Our home inspector says the heat exchanger is not covered in a home inspection. But the heating contractor showed us the crack. It is plainly visible and could have been seen by our inspector if he had taken the time to look. Is it fair that he should not be liable for this omission?

A. Home inspection contracts typically list heat exchangers as outside the scope of a home inspection. Likewise, industry standards, as defined by state and national associations, define heat exchangers as outside the scope. The reason for this disclaimer is that most heat exchangers are partially or totally inaccessible and cannot be inspected without dismantling the furnace.

This escape clause has led many home inspectors to overlook visible defects that could have been reported to buyers, if the inspector had simply looked into the burner chambers. The purpose of the disclaimer is to protect home inspectors from frivolous claims for cracks that could not have been seen. But many damaged heat exchangers have been identified by concerned home inspectors. Cracks in the lower portions of a firebox can sometimes be seen by shining a flashlight into the burner orifice. Rust flakes, black soot, or faulty flame patterns can also alert a home inspector to possible defects, if only the inspector will try to look.

The job of a home inspector is to report conditions that are "visible" and "accessible." If the crack in your heat exchanger is visible and accessible, that fact should override the disclaimer for inspection of heat exchangers. You should arrange for the home inspector to reinspect your furnace. Point out to him that the crack is visible and insist that he take responsibility for not having reported it. If he doesn't agree, ask him to submit the matter to arbitration or mediation.

Q. My new house has a major drainage problem in the basement. The builder installed a sump pump that operates constantly because of excessive groundwater. It stopped working during a power failure, which caused flooding and mold. According to my builder, there is no code requirement to drain water away from my house. Is this true?

A. Depending on which version of the building code is used in your area, the code definitely contains standards for site drainage around buildings.

According to section 1804.7 of the Uniform Building Code, "Provisions shall be made for the control and drainage of surface water around buildings."

If the International Residential Code (IRC) applies in your area, Section R405 states, "Drains shall be provided around all concrete or masonry foundations that retain earth and enclose habitable or usable spaces located below grade." Obviously, that would include basements. Furthermore, Section R406 of the IRC contains detailed specifications for the waterproofing of concrete and masonry basement walls.

Teralba Industries develops heat exchanger temperature control system

TERALBA Industries says an integrated Electronic Temperature Control System can be installed at the time of construction on the entire range of its Dimpleflo Modular Heat Exchangers.

This factory-fitted control system can be installed on the range of Dimpleflo Monotube and Multitube heat exchangers, from the 25mm unit right through to the largest 203mm flowpath unit.

The Electronic Temperature Control System uses advanced temperature sensors which constantly monitor the temperature of the product as it discharges from the heat exchanger.

Teralba Industries says this information is transmitted to a PLC control which, in turn, regulates the flow of the service fluid entering the heat exchanger with an electric or pneumatic modulating control valve.

The Electronic Temperature Control System incorporates a digital temperature display, which provides an adjustable temperature set point for the heat exchanger. Housed in an IP-55 weatherproof enclosure, the system can also provide a signal to allow it to be integrated into a central control system.

Focus: Heat exchangers

Heat exchangers sit at the core of every petrochemical facility, and represent a market segment projected to cross US$12.7 billion by 2012. Petrochemicals Middle East investigates the systems available, and how to find the model best suited to your budget.

Heat exchangers are devices specifically designed for the efficient transfer of heat from one fluid to another over a solid surface. This transfer of heat can either take the form of absorption or dissipation of heat. Heat exchangers can be found in everyday equipment from boilers, furnaces, refrigerators to air conditioning systems.

The exchangers used transfer heat from one liquid to another, without allowing them to mix. The exchange can be to alter the temperature, or state of liquids, either condensing or boiling as required.

Regardless of the function the heat exchanger fulfills, in order to transfer heat the fluids involved must be at different temperatures and they must come into thermal contact, as heat can flow only from the hot to cold, thus the heat is transferred via a metal plate isolating the two fluids.

Heat exchangers are found in most chemical, electrical or mechanical systems and they serve as the system’s means of gaining or rejecting heat. Some of the more common applications are found in heating, electronic equipment, ventilation and air conditioning (HVAC) systems, radiators or internal combustion engines, boilers, condensers and gas preheaters.

Giant plate heat exchangers enlarge the range

Alfa Laval reports that the new T50 model is the largest plate heat exchanger it has ever built, standing 4.5 metres high, weighing 30 tonnes and with a flow rate capacity of up to 975kg/second

Alfa Laval says its new T50 model is the largest Plate Heat Exchanger it has ever built.

Standing 4.5 metres high, weighing 30 tonnes and with a flow rate capacity of up to 975kg/second, the monster unit is ideal for central cooling systems in petrochemical refineries, chemical plants and off-shore oil and gas platforms.

In common with all Alfa Laval Plate Heat Exchangers, the T50 consists of a pack of plates stamped with a special pattern which, once assembled, form channels through which two fluids flow in counter-current to each other, exchanging heat in the process.

The corrugations reinforce the plate structure against differential pressures and also promote turbulence in the fluids.

This, in turn, increases heat transfer efficiency and also serves to inhibit scaling and fouling on the channel walls.

The T50 has a new plate system that improves heat exchanger performance for large cooling requirements.

The system enables three basic plates (low-theta, medium-theta and high-theta) to be combined in five different channel arrangements for specific temperature programmes.

The T50 can be supplied with plates in stainless steel or titanium, nitrile or EPDM gaskets and with connections to DIN or ASME standards.

Each plate provides 3.5 m2 of heat transfer surface meaning a complete unit can provide a massive 2880 square metres of heat transfer surface.

In addition, the exchanger portholes are 500 mm diameter, making it ideal for the cooling of large industrial processes.
