Abstract

The invention discloses a machine room air conditioner system and a control method thereof. The system comprises an outdoor unit and an indoor unit, and the outdoor unit is connected with the indoor unit. Temperature sensors and a pressure sensor are connected to an inlet pipeline and an outlet pipeline of a condenser of the outdoor unit. Temperature sensors are mounted on a water inlet pipeline and a water outlet pipeline. Temperature sensors and pressure sensors are connected to inlet pipelines and outlet pipelines of fluorine pumps. Bypass pipelines are connected to the outlet pipelines ofthe fluorine pumps. The other ends of the bypass pipelines are connected to the inlet pipeline of the condenser. Bypass electromagnetic valves are connected to the bypass pipelines. A temperature sensor and a pressure sensor are connected to an inlet pipeline of an electronic expansion valve of the indoor unit. A temperature sensor and a pressure sensor are connected to an outlet pipeline of an evaporator. An air return temperature and humidity sensor and an air outlet temperature and humidity sensor are further mounted on the evaporator. The control method comprises a control method of the indoor unit and a control method of the outdoor unit. The machine room air conditioner system is safe, reliable and good in stability, and the requirement of a machine room air conditioner can be met.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a machine room air conditioner and a control method thereof. Background technique [0002] With the rapid development of data centers, computer room air conditioners, as an important part of data center environmental control, are increasingly valued for their safety, reliability, and stability. [0003] The safety, reliability and stability of computer room air conditioners are mainly reflected in the following aspects: [0004] 1. The demand for constant temperature and humidity in the data center computer room requires the computer room air conditioner to be able to adjust the energy output in time to maintain a stable temperature and humidity in the data center computer room. [0005] 2. The computer room of the data center operates 24 hours a day without interruption, and the air conditioner in the computer room is required to achieve long-term uninterrupted operati...
