DIRECT EXPANSION AIR HANDLING UNIT HAVING APPARATUS FOR AUTOMATIC CONTROLLING AIR VOLUM OF BLOWER BY CHANGE OF REFRIGERANT FLOW

摘要

The present invention relates to a direct expansion type air conditioner having an automatic blower air flow control device according to a change in refrigerant flow rate, the purpose of which is to automatically adjust the air flow rate of the discharge and suction blower constituting the air conditioner according to the flow rate of the refrigerant supplied to the heat exchanger When the indoor temperature is stabilized and the operation amount of the outdoor unit decreases or the flow rate of the refrigerant decreases, the operating cost of the blower can be reduced by adjusting the blower volume by adjusting the output of the motor. The present invention provides a direct expansion type air conditioner having an air blower automatic control device capable of maintaining a high temperature. According to an aspect of the present invention, there is provided a direct expansion type large-capacity EHP (GHP) type air conditioner, comprising: a control controller for controlling an electronic expansion valve whose opening amount is controlled by opening and closing to adjust a flow rate of a refrigerant supplied to a heat exchanger of the air conditioner; One or more control controllers connected to the electronic expansion valves installed in each heat exchanger are connected to the circuit to collect and analyze the opening rate information according to the opening and closing of the electronic expansion valves, thereby controlling the air flow control means according to the flow rate of the total refrigerant supplied to the one or more heat exchangers. A wind volume control controller configured to be configured; Blower airflow automatic control device according to the refrigerant flow rate change further comprises a blower airflow automatic control device consisting of; air flow rate control means for adjusting the wind speed or the air flow rate of the suction blower and discharge blower according to the control of the airflow control controller A direct expansion type air conditioner having a feature of the invention.
