Abstract
A heat exchanger assembly for cooling of air includes a blower, an air duct and a heat exchanger integrated in a coolant circuit designed to allow coolant to flow therethrough and air to be applied to it. Heat from the air is transferred to the vaporizing coolant. The blower is arranged upstream of the heat exchanger in the airflow direction so that waste from the blower heats the air before reaching the heat exchanger. The heat exchanger is designed as tubular heat exchanger with tubes arranged in rows having a double-row design. A method for operating a climate control system for a combined refrigeration system and heat pump operation for cooling and for heating, and a method for identifying and prevention of icing of the evaporator of the climate control system are also disclosed.
