Water Loop System
Supplier:
Environmentally friendly with
maximum performance
Sustainability and energy efficiency are the basis for developing, manufacturing and operating AHT systems. As an environmental pioneer, AHT have been leading the industry with their innovations for more than 15 years – and that as standard.
How the AHT Semi Plug-in Water Loop System works?
The operation and components of AHT Semi Plug-in (SPI) System explained
With the SPI system form AHT, you receive a complete system for your food cooling and freezing needs, offering the option to couple the waste heat with heating or hot water processing. With this one-stop solution, AHT provides an efficient and compatible system for your market - it doesn't get any simpler than this. Step by step, we guide you through the modeules, components, and functions of our innovative system, which is based on the natural refrigerant R290. We start with the plug-in cooling and freezing cabinets as well as ice cream units from AHT. These devices can be individually placed in the market and only need to be connected to the power supply. The diverse placement options ensure maximum flexibility and can be changed at any time as needed. AHT offers a comprehensive selection of cooling and freezing chests- exactly to your specifications.

Waste heat unit & pump station
AHT offers two options for the waste heat unit and pump station:
1) Split-Version: The patented modular AHT pump station does not require its own machine room and can be placed, for example, in storage areas. The condenser is typically installed on the roof or outside of the building and is available in various types such as tabletop condenser, wall-mounted condenser, or V-shaped condenser.
2) Compact-Version: The pump station and waste heat unit are housed in a compact device that is typically installed on the roof or outdoor areas. The waste heat unit circulates the water-propylene glycol mixture to the units in the Semi Plug-in System and releases the waste heat to the ambient air. One or more waste heat units are sized and installed depending on the size of the system. AHT uses a dual pump approach for increase operational reliability- if one pump fails, the second pump automatically takes over. The pump station contains all components of the waste heat circuit as well as the corresponding electrical and control system.

Cooling & freezing units
In the next step, the AHT cooling and freezing devices are integrated and connected to the waste heat unit. AHT offers an extensive selection of cooling and freezing shelves, service counters, and other compatible devices, The waste heat generated during the cooling process is released into the ambient air.
All AHT cooling and freezing devices use the natural refrigerant R290. Within the circuit of the SPI system, a water-propylene glycol mixture is used.

Cold room aggregates
AHT offers a wide range of cold room units for your storage rooms. These are also integrated into the SPI system and operate in the same circuit as the cooling and freezing devices on your sales floor.
In the cooling cells, both compact and split units for cooling or freezing can be installed. The number of refrigeration units can be expanded as needed.

Hydraulic station & OSSM
With AHT, there is the possibility to use the waste heat from the cooling process wisely. For this purpose, a hydraulic station is installed, and the AHT OSSM (One Stop Solution Manager) is integrated. The OSSM acts as a control unit between the hydraulic station and the existing heating system and its components (fan coils, AHU, underfloor heating, backup heating systems) in your market. In addition to heating, hot water processing can also be integrated into the system.
When installing a split waste heat unit with an external pump station, the hydraulic station is usually installed next to the pump station, eliminating the need for a separate machine room. For compact waste heat units with an integrated pump station, the hydraulic station can be placed anywhere indoors. Optionally, there is also the possibility to mount the hydraulic station on a wall.

Heat Recovery
The heat generated by the cooling system is now supplied to the premises through the heating system. If the heating demand is higher than the supplied recovered heat, the brine temperature can be increased to cover a greater heat demand. This functionality comes into play during the colder seasons, reducing the heating load of the heating system and your costs.
Heat Pump
If raising the brine temperature is not sufficient to meet the heating demand, heat pumps can be integrated into the system. AHT offers air-to-water heat pumps as a backup system, which can also be used for cooling the commercial areas during the summer.
Alternatively, a water-to-water heat pump can be integrated into the ventilation system or the Air Handling Units to cover the additional heating demand.
The heat pump is integrated into the SPI system and is started only when needed. This reduces the heat pump's utilization and effectively lowers your costs.

Operation mode summer
During the summer months, the reversible air-to-water heat pump functions for space cooling. In this process, the cooled air is directly fed into the heating system to cool the premises. The heat generated by the cooling and freezing system is discharged into the surroundings via the waste heat unit.
Active Monitoring System
With the Active Monitoring Ticketing System various data (Alarms, Data, Functionality, etc) is reported to AHT to ensure the best possible operation of the units. The AMS can be setup or connected to an existing system if an interface is provided. With this essential add-on you are on the safe side and AHT supports you in its best possible way.
Summary
As you have now learned, our SPI system represents an energy-efficient solution that is designed with foresight. Our SPI system already meets all current and future FGAS regulations of the EU. AHT offers you individual consultation and professional project management to make your future-proof as well.
