Condensation by a water circuit
Supermarket refrigeration system.
- Technical features
intarloop is a supermarket refrigeration system, consisting of: DX cooling units distributed, with indirect condensation by a water circuit; and one or more units in parallel air-cooler connected to the condensation heat disipation.
Distributed cooling production allows to reduce and fractionate the load of HFC refrigerant in the installation, so that the risk of leakage is reduced.
Decentralization of the cooling production contributes a greater operation secutiry of the installation, that guarantees a high availability of the system when faced with the isolated failure of a single unit.
The installation of a double air-cooler or dry-cooler in parallel, provides a greater operational security.
The condensation water loop contains only closed-circuit water working at low hydraulic pressure. .
- Simple intallations
Intarloop system is very easy to install, thanks to its condensed water units pre-charged with refrigerant, and air-coolers or dry-coolers with inbuilt hydraulic unit/circuit.
Distributed cooling production allows adaptation of working temperatures to the needs of each service, thus obtaining an adequate degree of humidity for the best preservation of each product, and optimizing the performance of the systems.
- Energy saving
Condensing units incorporate high-efficiency scroll compressors with R134a refrigerant for positive temperature, or R449A for negative temperature.
Air-coolers or dry-coolers incorporate hydraulic group with electronic pump of variable flow, that adapts its functioning speed to the demand of the installation. Motor fans are equipped with speed regulators to reduce their consumption in low ambient temperatures or low load.
Intarloop system is applicable both in new installations and in existing centralized direct expansion facilities, where the update of refrigeration plant is desired. In fact, existing refrigerating displays are usable and easily converted to new refrigerants.
Intarloop system easily adapts to changes in the demand of refrigeration services. Condensing water loop is normally on PVC or PPR piping allowing easy modification and expansion.
Unlike other systems on the market, intarloop system is designed to work properly even at extreme ambient temperatures up to 45 °C, with condensing water temperatures up to 55 °C, and without the need to incorporate additional cooling equipment.
- Heat recovery
By means of cycle inversion, condensing units work as a heat pump recovering the heat of the water loop to defrost the evaporating units, thus avoiding the electrical consumption of electric defrost heaters.
Condensation heat of the water loop can also be easily recovered for winter climate control for the sales rooms, requiring only a minimal investment.
