Energy-conserving cooling device for eliminating room residual heat and control method thereof

Abstract

The invention relates to an energy-saving cooling device for removing room waste heat and a control method thereof. The device comprises an outdoor unit, an indoor unit and a control device thereof. The indoor unit comprises an indoor heat exchanger. The outdoor unit comprises an outdoor heat exchanger, a compressor, a throttling mechanism, a first bypass channel and a second bypass channel. The first bypass channel is branched off between the outdoor heat exchanger and the throttling mechanism. A first control mechanism for controlling the direction of cycle working fluids is arranged at a branching part. The first bypass channel is connected with a pipeline intersection between the throttling mechanism and the indoor heat exchanger. A cycle working fluids pump is also arranged on the first bypass channel. The second bypass channel is branched off between the indoor heat exchanger and the compressor. A second control mechanism for controlling the direction of the cycle working fluids is arranged at a branching part. The second bypass channel is connected with a pipeline intersection between the compressor and the outdoor heat exchanger, and the indoor and the outdoor of the room are respectively provided with a temperature sensor. The temperature sensors, the first control mechanism and the second control mechanism are electrically connected with the control devices respectively. Under the premise of ensuring the indoor cooling of the room, the energy-saving cooling device for removing room .waste heat and the control method thereof realizes the grading running and grading energy saving functions of the energy-saving device. No ventilation wall holes are required to be made and the introduction of dusts from the outside is avoided. Simultaneously, the system control is simple, the installation is convenient, and the production cost and installation cost are lowered.

Description

technical field [0001] The invention is an energy-saving cooling device for eliminating room waste heat and its control method, which belongs to the transformation technology of the energy-saving cooling device for eliminating room waste heat and its control method. Background technique [0002] In industrial production, there are often rooms with cooling load all year round, and the equipment in the room cannot be directly ventilated and cooled, such as: telecommunication base stations, communication switch rooms, etc. Statistical analysis shows that the power consumption of air conditioners in these occasions accounts for more than 50% of the total power consumption. Due to the large heat generated by the equipment, it needs to be refrigerated throughout the year, and the operating environment is relatively demanding, so direct ventilation cannot be used to reduce the room temperature. Therefore, in winter and spring and autumn, when the outdoor temperature is low, it is s...

AI Technical Summary

Problems solved by technology

Although this system solves the problem of relatively large holes through the wall of ventilation pipes and damage to buildings caused by installation, but because the air conditioner and the device are two independent systems, the control between the two will be more complicated, which will bring difficulties in control , Moreover, the purchase and installation of two sets of equipment significantly increase the initial investment and installation costs
