As a result, many new air-conditioning solutions have emerged, and inter-row air-conditioning is one of the effective solutions. Under the wave of building green data centers advocated by the state, water-cooled inter-row air conditioners have obvious advantages, but ordinary water-cooled inter-row air conditioners mostly use tube-fin heat exchangers, which have low heat transfer efficiency and large thermal resistance, resulting in increased fan power consumption , poor energy saving; in recent years, microchannel heat exchangers have been applied and developed in the field of refrigeration and air conditioning due to their high-efficiency heat transfer, compact structure, and small size. For energy saving, a new type of water-cooled micro-channel inter-column air conditioner has been developed.

如图1所示，本实用新型的一种高效微通道水冷列间空调，其结构由风机、电加器、加湿器、放气阀、换热器盘管、空气过滤器和电动调节阀构成，滤管与水阀连接，水阀的另一端与换热器盘管连接，换热器盘管的另一端与电动调节阀连接，电动调节阀与水阀连接； As shown in Figure 1, a high-efficiency micro-channel water-cooled inter-row air conditioner of the present utility model is composed of a fan, an electric heater, a humidifier, an air release valve, a heat exchanger coil, an air filter and an electric control valve. , the filter tube is connected to the water valve, the other end of the water valve is connected to the heat exchanger coil, the other end of the heat exchanger coil is connected to the electric regulating valve, and the electric regulating valve is connected to the water valve;
换热器盘管的一侧设置有空气过滤器； One side of the heat exchanger coil is provided with an air filter;
换热器盘管的另一侧设置有加湿器，加湿器的另一侧设置有电加热，电加热的外侧设置有风机。 The other side of the heat exchanger coil is provided with a humidifier, the other side of the humidifier is provided with electric heating, and the outside of the electric heating is provided with a fan.
冷冻水进入水冷列间空调，在微通道换热器集流管中分流进入多束扁平管，经过4个流程后，经冷冻水电动调节阀流出列间空调；在此过程中，微通道换热器与EC风机吸入的回风进行高效换热，系统根据机房设定温度及回风温度，计算制冷需求,水流量调节阀采集制冷需求信号来调节阀的开度，控制流过换热器盘管的水流量。当制冷需求大时，阀门的开度变大，水流量增加。当制冷需求小时，阀门的开度减小，水流量减少。另外，列间空调系统根据室内温度及回风温度来判定EC风机运行的数目及风机转速。室内温度高于设定值，EC风机升高转速；室内温度低设定值，EC风机降低转速；系统会根据通道内的温湿度情况，控制加湿器和电加热器的运行。 Chilled water enters the water-cooled inter-row air conditioner, and is divided into multi-bundle flat tubes in the micro-channel heat exchanger header. The heater and the return air sucked by the EC fan perform efficient heat exchange. The system calculates the cooling demand according to the set temperature of the machine room and the return air temperature. The water flow regulating valve collects the cooling demand signal to adjust the opening of the valve and control the flow through the heat exchanger. Coil water flow. When the cooling demand is large, the opening of the valve becomes larger and the water flow increases. When the cooling demand is small, the opening of the valve is reduced and the water flow is reduced. In addition, the inter-row air-conditioning system determines the number of running EC fans and the fan speed according to the indoor temperature and the return air temperature. When the indoor temperature is higher than the set value, the speed of the EC fan is increased; when the indoor temperature is lower than the set value, the speed of the EC fan is reduced; the system will control the operation of the humidifier and electric heater according to the temperature and humidity in the channel.
