Conventional heat exchangers established that their design should be reviewed to become more suitable for HVACR system requirements and operating conditions. Challenges with the heat exchangers include their adaptability to the different refrigerants used in HVAC systems, acclimatizing to different air flow rates, and evading the issues related to the build-up of condensate. All these requirements call for significant design transformations to upscale the heat exchangers to meet its expectation.
Danfoss Micro-plate heat exchangers (MPHE) are drastically transforming the heat exchanger solutions. Danfoss MPHE offer excellent heat transfer technology with the least use of refrigerants. MPHE is aiding the development of highly advanced, efficient & low-impact products for HVAC systems.
Danfoss micro-plate heat exchangers are highly effective at transferring thermal energy for greater efficiency & compact design and have wide-ranging applications. Using Danfoss Micro-plate heat exchanger solutions, your refrigeration system requires 30% less refrigerant, reduces weight, uses less space and requires less energy to carry out its functions. Furthermore, by combining energy efficiency with the least use of resources (refrigerants, energy and space), Danfoss’ MPHEs are leading the greener HVAC solutions for present and future refrigeration systems. It is expected that in the coming five years, the MPHE’s market share is expected to upsurge to 40%.
Danfoss’ latest innovation in energy-efficient heat exchangers for sustainable cooling includes the Z-designed micro-plate heat exchangers, which provide higher efficiency evaporators. Their features include dimple-design plates, which function in an asymmetrical refrigerant circulation which is in a Z-shape pattern to augment the surface area and hence increase the heat transfer.
11 outstanding reasons for you to choose Danfoss’ MPHE
1) Smaller sizes & compact design
The highly compact design of MPHEs means smaller coils can be used in place of an F&T coil while having equivalent performance. The size of the cooling units can be reduced to almost 35% of the previous requirements, ultimately leading to competitive advantages like reduced carbon footprint and smarter logistics requirements. Depending on the different kinds of applications, these smaller sized micro-plate heat exchangers result in an extraordinary increase in performance and the energy efficiency of the HVAC system.
2) Low Weight
Danfoss’ MCHEs weigh 68% less than the prevalent F&T coils. These energy-efficient heat exchangers assist you in producing smaller, lightweight units having equivalent performance. These characteristics have a lot of utility, mainly in mobile cooling systems. These heat exchangers’ reduced size and weight result in lower handling and transportation costs and reduced labour costs.
3) Aluminium-based design
Danfoss’ micro-plate heat exchangers are manufactured using aluminium, a low-density metal that prevents galvanic corrosion, which is a common issue seen with F&T coils. The use of long-lasting aluminium alloys and non-corrosive fluxes in the micro-channel heat exchangers fabrication process provides high corrosion-resistant properties.
4) Lower hold-up volume
Danfoss’ advanced Micro-plate design provides a significantly improved heat transfer mechanism while using lesser refrigerants. Micro-plate heat exchanger solutions provided by Danfoss have a hold-up volume that is almost 77% lower when compared to an F&T coil.
5) Ease of cleaning
The robust design of Danfoss’ MCHEs makes it very easy to clean, unlike the F&T coils from which dust and dirt are tough to remove. The cleaning procedure is assisted by the low thickness of the micro-channel heat exchanger making it seamless and quick to clean. The core of Danfoss’ energy-efficient heat exchanger is extremely sturdy, due to which the fins are very well protected from bending and any other mechanical damages. Brazed fins provided in the heat exchangers are strong and simple to clean, ultimately reducing ownership costs throughout the product lifecycle.
6) Greater air-side heat transfer efficiency
Danfoss’ MCHEs effectively tackle one of the challenges related to the coil performance and provide higher air-side efficiency than the F&T coils. These smartly designed energy-efficient heat exchangers offer higher tube surfaces and better tube-to-fin joints and continuous contact between the ambient air and the metal surface. This increase the overall efficiency of the heat transfer system.
7) Lower pressure drop per unit heat transfer
Pressure drop is very low in Danfoss’ micro-plate heat exchangers, which permits you to use a smaller air side fan and reduce energy usage. These advanced microchannel heat exchanger establishes 60% less airside pressure drop and consequently reduces the power consumption of the fan, parallelly reducing the noise level which could be produced by the fans. To increase the capacity of the cooling system, the low resistance of Danfoss’ plate heat exchanger solutions makes it possible to enhance the airflow performance.
8) Brazed tube - Fin joint features
When air gaps are present between the different layers of the heat exchangers, they reduce heat transfer levels. But in Danfoss micro-plate heat exchangers, all the parts are brazed together; due to this, there are no air gaps in the joint; hence, the heat transfer efficiency is highly improved. Danfoss’ 30 years of constant development has ensured the outstanding performance and efficiency of the Brazed Plate Heat Exchanger (BPHE).
9) Design flexibility
Danfoss’s extensive product range gives you a lot of flexibility, both in terms of the coil size and the various mounting options. Based on the required performance and application, the heat exchanger for chillers are manufactured using micro-channel tubes of different widths, changing the number and sizes of the port. Danfoss MCHEs are available to a size of (1.5 x 4) metres. Along with these wide-ranging options, we offer a variety of mounting accessories to complement the type of installation.
10) Low noise levels
Danfoss’ micro-plate heat exchangers have an advanced un-obstructed airflow design that reduces the level of noise which is a notable advantage in the case of residential HVAC applications. Plate heat exchangers have a straight-through airflow which provides a lower pressure drop and needs less fan power to function.
11) Price stability
Danfoss’ heat exchangers incorporate their unique design, due to which these can be made highly compact in size. MCHE’s are fabricated with less metal as compared to F&T coils. This lesser metal content represents a smaller proportion of the total cost, consequently making these MCHEs least vulnerable to the price fluctuation of the raw materials.
