Description

ventilatore di condensazione può provocare il danneggiamento di altri componenti dell apparecchio. condensing fan can damage other components of the appliance.

Inoltre, la presenza del ventilatore di condensazione provoca un maggior consumo energetico da parte dell'apparecchio ed un maggiore impatto ambientale complessivo, anche legato alla costruzione del ventilatore stesso^/^F Furthermore, the presence of the condensing fan causes greater energy consumption by the appliance and a greater overall environmental impact, also linked to the construction of the fan itself ^ / ^ F

Scopo quindi della presente invenzione à ̈ quello di risolvere i suddetti problemi della tecnica anteriore fornendo un apparecchio frigorifero a temperatura positiva di tipo commerciale ad alta efficienza caratterizzato da una elevata potenza frigorifera e dalla condensazione priva di ventilatori. Therefore, the object of the present invention is to solve the aforesaid problems of the prior art by providing a high efficiency commercial refrigeration appliance with positive temperature characterized by a high cooling capacity and by condensation without fans.

Un altro scopo della presente invenzione à ̈ quello di fornire un apparecchio frigorifero a temperatura positiva di tipo commerciale ad alta efficienza privo di ventilatore di condensazione e dotato di compressore a bassa pressione, pur mantenendo prestazioni frigorifere analoghe a quelle degli apparecchi della tecnica nota. Another object of the present invention is to provide a high efficiency commercial type positive temperature refrigerating appliance without a condensation fan and equipped with a low pressure compressor, while maintaining cooling performance similar to that of the prior art appliances.

Inoltre, uno scopo della presente invenzione à ̈ quello di fornire un apparecchio frigorifero a Furthermore, an object of the present invention is to provide a refrigerating appliance a
