Soler & Palau not only ensured a technically excellent product, but also paid special attention to the product's casing. As it is a unit that will be installed in plain view, a very careful aesthetic was sought, in addition to an optimised aerodynamic design.

Plug-and-play reversible CO2 heat pump

Daikin responds to new energy challenges with the launch of its new Full Inverter range with Modular and High Temperature configuration: a solution that combines efficiency, reliability, and sustainability.

Committed to ecological transition, this series will be available with two refrigerants with low global warming potential (GWP):

R-454C – GWP: 145

R-290 (propane) – GWP: 1

Air conditioning installations are facing ever greater challenges, which are driving the shift from traditional systems to new solutions that meet these challenges.

In order to achieve the carbon neutrality targets set by both the European Union and national governments, it is essential to anticipate and launch the most advanced solutions that can achieve these goals. Daikin EWY(E)(K)-CZ air source heat pump units are an ideal solution to meet these challenges.

The new EWY(E)(K)-CZ units offer a versatile version for cooling, heating, and DHW production, reaching temperatures of up to 75°C with propane and 70°C with R-454C.

Thanks to their Full Inverter technology, present in both compressors and EC fans, these units guarantee optimal performance with reduced operating costs and optimized service life.

The power of each of the modules will be 100, 125, and up to 150 kW, with all three being combinable with each other, thus providing great versatility. This flexibility makes the series an ideal solution for both new projects and renovations, facilitating scalability and intelligent demand control.

Four units can be connected per row (up to 600 kW) and up to 16 units (4 rows) can be controlled.

Daikin Altherma X is a mixed air-to-air and air-to-water heat pump for the residential market, equipped with the new low environmental impact refrigerant R454c.

Thanks to the possibility of simultaneously connecting direct expansion air conditioning units and a classic hydrokit from a multifunction heat pump, this device allows us to provide the following services:

• Cold/hot air for air conditioning, using up to four direct expansion refrigerant units.

• Classic water heating, with underfloor heating or radiators (maximum flow 70ºC)

• Cooling via cooling floor.

• DHW production.

This product will thus add to traditional split or bibloc multifunction heat pumps the possibility of providing air conditioning through direct expansion, offering the following advantages:

• Easier installation: no inertia, secondary pumps, purge valves, switches, etc., just refrigerant piping to the indoor units.

• Faster cooling, with smaller consoles than water-based ones.

• Greater dehumidification of the environment, as lower temperatures are reached in the refrigerant coil.

• Can be used with medium/high temperature radiator systems, thanks to the use of R454c (maximum heat delivery temperature 70ºC). Excellent for boiler replacement.

• More options for outdoor unit location. Refrigerant connection, with the possibility of long distances and uneven surfaces, and without the restrictions of R290 systems, as R454 is an A2L type refrigerant (same safety classification as R32).

• Lower environmental impact than R32 systems, as R454c has a GWP of 148.

The ecoGEO+ LITE 1-6 PRO heat pump is suitable for geothermal, aerothermal, and hybrid (geothermal + aerothermal) collection systems, making it perfect for multi-family buildings that require heating, cooling, and domestic hot water (DHW). In addition, its compatibility with photovoltaic systems improves energy efficiency, contributing to self-consumption.

With very low noise levels and a design that makes installation extremely simple, this new heat pump from Ecoforest is an ideal choice for both developers and homeowners. Combining cutting-edge technology, sustainability, and efficiency, the ecoGEO+ LITE 1-6 PRO sets a new standard in the air conditioning market.

The H-Pack monobloc air-to-water heat pump is an advanced solution for residential air conditioning, designed to provide heating, cooling and domestic hot water (DHW) with high energy efficiency and very low environmental impact.

It is a compact unit for indoor installation, even in small spaces. Air flow is captured from the outside through small ducts. The entire refrigerant circuit is integrated into a ventilated enclosure that guarantees the safe operation of the equipment in the event of any risk of refrigerant leakage.

H-Pack has an advanced control system that allows the management of up to two circuits and is optimised for the integration of the heat pump into hybrid systems, managing both generators according to efficiency or economic savings criteria. It is designed to communicate with boilers using the Opentherm protocol, 0-10 volt signal and On-Off signal, allowing it to communicate with virtually any generator on the market.

Three variants of the equipment have been developed to adapt to the different use cases described below:

1 – H-Pack: Heat pump that integrates a basic hydraulic system.

2 – H-Pack for hybridisation: System that integrates the heat pump and a hydraulic assembly (Hydrobox) that facilitates the installation of the equipment in a hybrid system with a boiler. The control system and the additional Hydrobox optimise system performance and ensure proper operation of the assembly under variable demand conditions.

3 – All-electric H-Pack: System that integrates the heat pump and a Hydrobox that integrates an electric resistance to support the main heat pump generator for peak demand conditions.

The development carried out by KEYTER Technologies arose from the need in the residential sector to

integrate centralised air conditioning and DHW production into a single system, achieving levels of

efficiency that not only comply with the efficiency values set by the Technical Building Code (CTE) but

also exceed them.

The conceptual diagram of the product is shown in Figure 1, whose main distinguishing feature

from other simultaneous production systems is that it takes advantage of the heat generated in

the discharge of hot gases from the compressor, generating five possible modes of

operation:

I. Heating generation

II. Simultaneous heating and DHW generation

III. Cooling generation

IV. Simultaneous cooling and DHW generation

V. DHW generation

UNIT is an innovative refrigerated cabinet designed for the display and preservation of beverages at positive temperatures. Despite its compact dimensions, UNIT sets a new standard for sustainability and design in the refrigeration industry. As Epta's first product conceived under the principles of the circular economy, UNIT fully embraces the 4R philosophy: Reuse, Repair, Refurbish and Recycle. Its structure is designed to maximise resource efficiency, significantly reducing waste and environmental impact throughout its entire life cycle.

What really sets UNIT apart is its pioneering use of cork as an insulating material. This natural and renewable resource not only offers exceptional thermal performance, but also drastically reduces the product's carbon footprint (85% less compared to standard cabinets), making it a sustainable alternative to conventional materials. The innovative “cassette” system ensures easy maintenance and quick replacement of components, increasing durability and reducing service times. Its design, inspired by the technology sector, incorporates smart connectors, ergonomic handles, a dual-function lid and base, and an elegant gradient perforated grille that optimises ventilation and provides a refined aesthetic.

By combining functionality, eco-innovation and premium quality, UNIT redefines the concept of sustainable refrigeration solutions, responding to the demands of a market that is increasingly focused on environmental and design excellence.

DAIKIN's Sky Air asymmetric combinations represent an advanced solution for the technical cooling of sensitive infrastructures, such as server rooms, data centres, laboratories, and technological spaces. Unlike conventional systems, these combinations allow indoor units with greater capacity than the outdoor unit to be connected, optimising heat transfer in conditions of low relative humidity.

The system is based on DAIKIN's Inverter technology, which dynamically adjusts cooling power, and on a design logic that prioritises operational continuity and thermal efficiency. This allows it to operate at higher evaporation temperatures (Te), avoiding the downtime typical of traditional systems and ensuring constant operation, which are fundamental requirements in such critical environments.

Water-water chillers are air conditioning units that use water as a medium to absorb and dissipate heat. Instead of exchanging heat directly with the outside air (as in air-water chillers), they do so through a water circuit connected to a cooling tower or other hydraulic system.

When this type of chiller incorporates a magnetic levitation compressor, it becomes a highly efficient, low-maintenance and highly reliable solution. This compressor does not use oil or mechanical bearings, but rather the compressor shaft ‘levitates’ thanks to electronically controlled magnetic fields.

Midea's Mars Large range represents a technological evolution in air-water air conditioning systems, designed to meet the demands of large residential, commercial and industrial installations. With power ratings ranging from 50 to 70 kW, this series is positioned as a robust, efficient and sustainable solution, ideal for decarbonisation projects, boiler replacement and electrification of thermal systems.

ZeLoop™ distributed cooling system (in its application with the Clima LP plant). The ZeLoop™ system is based on a range of autonomous Distributed Condensing Units (DCUs) that use CO₂ (R744) as a refrigerant in an ultra-high efficiency subcritical cycle. The fundamental innovation lies in the condensation method.1 Each ZeLoop™ unit condenses the CO₂ locally through a cascade heat exchanger, which is fed by a primary loop of a secondary fluid pumped at low pressure. Although the ZeLoop™ system can operate with various cold sources, its maximum performance is achieved when integrated with a Clima LP plant, which supplies it with liquid R-1234ze(E) refrigerant, oil-free and at low pressure (< 3 bar).

This distributed cascade architecture addresses the shortcomings of conventional systems, such as the low efficiency of optimised transcritical CO₂ systems in hot climates and the complexity and operational risks of water-glycol circuits.

INTARCON's new range of intarCUBE A2L units is presented as the best low greenhouse effect solution for supermarkets and convenience stores. Due to the characteristics and properties of the refrigerant, they are a long-term solution for refrigeration installations of up to 40 kW.

Refrigerants classified as A2L combine low toxicity (class A) with low flammability (2L), characterised by a reduced flame speed. These refrigerants have been developed as a low environmental impact solution, with a GWP typically below 150, in line with the restrictions imposed by environmental regulations such as the F-Gas Regulation.

Among their technical properties, they have working pressures similar to traditional HFCs, which facilitates their application in new systems or retrofit processes. Due to their slight flammability, the use of A2L requires compliance with safety measures such as leak detection, adequate ventilation and a hermetic system design.

A2L refrigerants therefore represent an appropriate technical and regulatory solution for small and medium-sized installations, especially in commercial applications, where a transition to low GWP gases is required without compromising safety or performance.

Daikin, as a complement to the most efficient air conditioning equipment and in response to the regulatory framework, has developed an energy control and monitoring system that can be adapted and customised to any installation.

DAIKIN's customised BEMS solution is designed to optimise the management and control of a building, adapting specifically to the customer's needs. This platform integrates air conditioning, ventilation, energy, lighting and other technical services from any manufacturer or supplier into a single control and monitoring system. Thanks to its adaptability and scalability, it can be adjusted to any type of environment, from small offices to large industrial facilities.

The BEMS system focuses on maximising the performance of facilities and air conditioning units through intelligent and automated management.

Based on field controllers running on Niagara, it allows any type of signal or protocol to be integrated and controlled, thus providing a global solution for all systems in the facility, regardless of the manufacturer. In its user environment, it allows parameters such as temperature, humidity and air flow to be adjusted according to occupancy and environmental conditions, reducing energy consumption and improving comfort.

It also facilitates equipment maintenance by detecting anomalies and generating alerts based on predictive logic, which can sometimes be configured by users, all backed by continuous energy monitoring, both supplied (through the installation of energy meters) and consumed (with direct integrations from energy suppliers via APIs), which ultimately enables the creation of detailed energy reports that allow managers and/or owners to analyse system behaviour and make informed decisions.

Daikin's customised BEMS solution is presented as a comprehensive proposal for the need for a centralised control and monitoring system, offering not only system programming and configuration, but also real-time monitoring and identification of areas for improvement in the installation based on the data recorded.
