Description

TECHNICAL FIELD

[0002] The single cold -air machine for refrigeration engineering is an important component of a cold storage refrigeration system, and its main function is to provide fresh air for public places such as enterprise workshops and commercial entertainment venues and reduce the temperature. The floor type cold -air machine is one of the common types, and has the characteristics of energy saving and environmental protection.

[0003] The working principle of the cold -air machine is to absorb the heat in the air through the heat exchanger, thereby reducing the air temperature. In the refrigeration process, because the surface temperature of the heat exchanger is low, the water vapor in the air is easy to condense into water droplets on the surface of the heat exchanger. When the cold -air machine continues to work, these water droplets will be wrapped up by the airflow generated by the fan and blown out with the cold air. If the humidity of the environment where the cold -air machine is located is high, the water vapor content in the air will also increase accordingly. The number of water droplets condensed on the surface of the heat exchanger will also increase, thereby exacerbating the problem of water vapor content in the air blown out by the cold -air machine. This problem not only affects the refrigeration effect of the cold -air machine and reduces its working efficiency, but also may cause adverse effects on the indoor environment, such as increasing the indoor humidity and causing equipment corrosion. Therefore, a single cold -air machine for refrigeration engineering is needed to solve the above problems. UTILITY MODEL CONTENTS

The air inlet fan 3 starts to work and inhales air from the external environment. The air passes through the finned heat exchanger 2, and the refrigerant in the cooling circulation pipe absorbs the heat in the air, so that the temperature of the air is reduced. In this process, the water vapor in the air will condense into water drops due to the low temperature of the surface of the finned heat exchanger 2. The cooled air enters the air outlet shell 1. The air is guided by the top air deflector 12 and the bottom air deflector 11 in the air outlet shell 1, and a certain air flow path is formed. The condensed water drops flow down along the inner wall of the air outlet shell 1 and the top air deflector 12 and the bottom air deflector 11.
