Mitsubishi Electric energy-saving heat exchangers

New energy-saving, AA-rated M Series models from Mitsubishi Electric offer combination of cutting-edge inverter technologies with highly efficient heat exchangers.

This means highly efficient heat exchangers deliver remarkable energy efficiency at the quietest operation possible.

Mitsubishi Electric heat pump systems have always been among the quietest on the market and with its super-quiet 'Silent Mode' of operation at just 19dB, the MSZ- GE Series is now the quietest heat pump available.

The inverter-driven heat pump air conditioning units in the MSZ-GE range deliver exceptionally efficient heating or cooling.

With a choice of 4 new indoor units that can be used in a single split system or as part of an MXZ Multi system, the line-up offers complete flexibility for smaller multi-room applications.

The heat exchanger capacities of both the indoor and outdoor units have been increased to enhance overall heat exchange efficiency levels, yet the new 'Silent mode' setting added to the fan speed settings ensures a super-quiet operation below 20dB for the smaller models making it ideal for bedrooms.

Added to this is a new, compact wall-mounted unit design of just 798mm which fits neatly above a standard 800mm-wide door.

The MSZ-GE indoor units are engineered so that multiple indoor units can also be connected to a single MXZ Multi outdoor unit, reducing outdoor installation space considerably.

This includes the Power Multi MXZ-8A140VA outdoor model which can run up to eight indoor units simultaneously.

Rittal IP54 Air-Air Heat Exchangers offer low energy

Rittal Air-Air Heat Exchangers can lead to attractive cost savings over refrigerant based air conditioners due to their simple design, low energy consumption and minimum maintenance.

Air-air heat exchangers utilise the ambient air to cool the air within the enclosure interior using only two working parts. Extracting heat from within the enclosure and releasing it into the surrounding environment, the exchangers operation is based on the counterflow principle.

Completely separate airflows are routed through the heat exchanger module by powerful fans which control the internal and external airflows. (Thermal winding protection on the fan motors is provided as an added safety feature). The exchanger matrix, which is made of aluminium, make the unit light and offers maximum durability.

Units can be mounted internally or externally on the wall or roof of an enclosure. Spanning between 12 and 90W/K the range follows a similar platform design including appropriation to UL and are available ready for connection along with wiring and cutout drawings. Sizes and cut-out dimensions match the TopTherm cooling unit generation which gives the exchangers the added adaptability of being interchangeable with TopTherm cooling units.

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.
