Embodiment Construction

[0013] The present invention provides a spiral evaporator of a flooded central air-conditioning system. In order to make the purpose, technical solution and effect of the present invention clearer and clearer, the present invention will be further described in detail below. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0014] like figure 1 The spiral evaporator of a flooded central air-conditioning system shown includes an input pipe 110 provided with a refrigerant inlet and an output pipe 120 provided with a refrigerant outlet, and a spiral evaporator is arranged side by side between the input pipe and the output pipe. The row pipe 130, the two ends of the helical row pipe are respectively connected with the input pipe and the output pipe, wherein, a separation plate 111 for separating refrigerant and oil is arranged in the input pipe, and the separation plate is distr...

Abstract

The invention provides a spiral evaporator for a hydraulic filling type central air conditioning system. The spiral evaporator comprises an input pipe provided with a refrigerating agent inlet and an output pipe provided with a refrigerating agent outlet. Spiral pipe banks are arranged between the input pipe and the output pipe side by side. The two ends of each spiral pipe bank are communicated with the input pipe and the output pipe respectively. A separation board used for separating a refrigerating agent and engine oil is arranged in the input pipe. The separation board is distributed in the pipe diameter direction of the input pipe, so that the interior of the input pipe is divided into an upper space and a lower space which are communicated. By the adoption of the spiral evaporator for the hydraulic filling type central air conditioning system, engine oil backflow efficiency can be improved through the evaporator, the problems that refrigerating efficiency and operation reliability are lowered due to engine oil sedimentation of a refrigerating system can be effectively solved, the refrigerating efficiency of the air conditioning system adopting the spiral evaporator can be improved, operation reliability is improved to a great extent, and operation cost is reduced.

Description

technical field [0001] The invention relates to the technical field of central air-conditioning, in particular to a spiral evaporator for a flooded central air-conditioning system. Background technique [0002] Refrigeration systems are widely used in production, life, refrigeration and other fields. Freon refrigeration system is currently the most widely used and most mature refrigeration system. Because of the good mutual solubility between Freon refrigerant and compressor lubricating oil, it will cause compressor The lubricating oil in the machine is discharged into the evaporator in gaseous form with the operation of the machine and the freon refrigerant. If the oil separator does not have a good oil separation effect or the system does not return oil smoothly, a large amount of lubricating oil will remain in the evaporator pipe. On the one hand, it will directly affect the cooling of the system. On the other hand, the machine cannot run due to oil shortage and needs to ...
