AI Technical Summary

Technical Problem

The heat exchanger of the traditional V-fin heat pump unit has uneven wind speed on the wind surface, resulting in a decrease in heat exchange performance and frost at the bottom, affecting operation.

Method used

The heat pump unit is designed to have a wide upper and narrow upper structure, increase the air inlet, optimize the angle and bottom spacing of the heat exchanger, and set a bevel and support at the upper end of the box to increase the wind barrier between adjacent units to improve the uniformity of the wind field and heat exchange.

Benefits of technology

The wind speed and wind field uniformity at the bottom of the heat exchanger are improved, wind noise is reduced, frost is avoided, maintenance space is increased, and the operation reliability and heat exchange efficiency of the heat pump unit are improved.

Abstract

The utility model relates to a heat pump unit and a heat pump system. The heat pump unit comprises a box body, a heat exchange mechanism, a supporting frame and a supporting piece. The heat exchange mechanism comprises a heat exchanger obliquely and symmetrically arranged above the box body, a water pan arranged below the heat exchanger and a fan arranged above the heat exchanger. The top width of the heat exchanger is larger than the width of the box body, and the included angle and the distance of the heat exchanger are specific values, so that the wind field uniformity of the heat exchanger is effectively improved, and the heat exchange efficiency of the heat pump unit is improved. Moreover, the utility model further provides a heat pump system, the heat pump system comprises a plurality of heat pump units and wind shields arranged between the adjacent heat pump units, independent air channels are isolated for the adjacent units through the wind shields, mutual interference is avoided, the uniformity of a wind field is effectively improved, and therefore the heat exchange efficiency of the heat pump system is further improved.
