Air mixing type air conditioner and control system thereof

Abstract

The invention discloses an air mixing type air conditioner, which comprises a cabinet (1), an air inlet valve (2), a return air valve (4) and an air blower (7); three lateral surfaces of the cabinet (1) are orderly provided with an air inlet (8) for introducing outdoor fresh air, a return air inlet (9) for introducing indoor recycled air and an air outlet (10) of the air blower (7); the air inletvalve (2), the return air valve (4) and the air blower (7) are respectively arranged on the inner sides of the air inlet (8), the return air inlet (9) and the air outlet (10); and an inner space of the cabinet (1) is an air mixing chamber (12). The air mixing type air conditioner is characterized in that: the air inlet valve (2) and the return air valve (4) are respectively equipped with a first steering engine (3) and a second steering engine (5); and the steering engines (3 and 5) transmit power to the air inlet valve (2) and the return air valve (4) through a steering engine transmission mechanism (11), so that the opening of the air inlet valve (2) and the return air valve (4) is adjusted according to control signals.

Description

Technical field [0001] The invention relates to a mixed air conditioner, in particular to a mixed air conditioner for adjusting the temperature of indoor air. The invention also relates to a control system for controlling the mixed-air air conditioner. Background technique [0002] The equipment in the telecommunications equipment room works in a relatively closed environment. A large number of equipment generates a lot of heat during operation. Since they cannot exchange heat with outdoor air, the heat can only be controlled by the air conditioning in the equipment room for temperature control. In different seasons, although the temperature difference between indoor and outdoor in the computer room is large, for example, the temperature difference between indoor and outdoor can reach more than 30℃ in winter. However, because the computer room is airtight and the indoor temperature is still high, the air conditioner is still in a cooling state, which will seriously consume electr...

AI Technical Summary

Problems solved by technology

However, this patent does not describe the specific structure of the electric regulating valve.

The usual electric control valve has large volume and low precision, which will affect the volume, control accuracy and operating cost of the whole system

In addition, the patent uses a PLC industrial computer for control, which increases the system cost and limits the upgrade of system functions.
