Embodiment Construction

[0044] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0045] The refrigerant direct refrigeration system and control method of the present invention directly use the refrigerant to cool down the cooled equipment, which reduces the third-party medium, saves the relevant pipeline space, reduces the volume, and has a wider application range. Next, the refrigerant direct refrigeration system and the control method of the system will be described in detail.

[0046] The refrigerant direct refrigeration system of this embodiment mainly includes a control panel, a cooling plate 11, and two sub-refrigeration systems: a first sub-refrigeration system and a second sub-refrigeration system. The cooling plate 11 has a refrigerant inlet and a refrigerant outlet, and is placed by the cooling equipment. On the cooli...

Abstract

The invention discloses a refrigerant direct cooling system and a control method thereof. The system comprises a control board, a cooling plate and two sub-cooling systems, wherein the cooling plate has a refrigerant inlet and a refrigerant outlet. Each sub-cooling system all comprises a compressor, a condenser, wherein the refrigerant output from the compressor is delivered to the condenser, after cooled by the condenser to be conveyed to the refrigerant inlet of the cooling plate and delivered to the compressor through the refrigerant outlet. A temperature sensor is arranged on the cooling plate to collect the temperature signal and send the collected signal to the control board, which controls the operation of two sub-cooling systems.The refrigerant direct cooling system and the control method thereof reduces the system volume, the refrigerant cools the cooling plate directly with rapid cooling speed and high security; due to the adoption of two sub-cooling systems, the cooling system can be a mutual backup; due to the large cooling interval, the minimum capacity of the cooling system is extended downward; high control accuracy has been realized due to the adoption of PID frequency control.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to a refrigeration system and a control method. Background technique [0002] The equipment generates a lot of heat during operation, and the refrigeration system is required to cool down the equipment to ensure the normal operation of the equipment. [0003] At present, the cooling systems on the market are relatively large in size, such as water coolers (cooling the water first and then cooling the equipment), and radar chassis, laser equipment and other equipment require small cooling systems. Therefore, the large-volume cooling systems on the market cannot meet the requirements need. Contents of the invention [0004] The invention provides a refrigerant direct refrigeration system, which solves the problem of large volume of the existing refrigeration system. [0005] In order to solve the problems of the technologies described above, the present invent...
