Description
Technical Field
The invention belongs to the technical field of air conditioner evaporators, and particularly relates to a liquid type evaporator for an air conditioner.
Background
Reliability and stability are basic prerequisites for designing large commercial water chilling units. Screw-type water chilling units are no exception. Generally, the screw machine set allows partial suction and liquid carrying, and has the advantage that the sucked partial liquid refrigerant cools a motor at the suction end of the compressor, absorbs heat to become saturated vapor, and is sucked into a compression chamber by the screw compressor for compression and recycling. However, if there is an excessive amount of liquid refrigerant that has not been in time to become saturated vapor, it enters the compression chamber, because of the incompressibility of the liquid, the screw and the bearing will be subjected to very large force if compressed forcibly, which is generally called "hydraulic compression", and if compressed for a long time, it will cause damage to the screw compressor, and will seriously cause the compressor to be scrapped. Therefore, how to avoid or reduce the amount of suction liquid becomes an important part of the design of the flooded evaporator. Generally, a suction baffle and a liquid baffle are arranged in a flooded evaporator, but most of the existing liquid baffles and the existing suction baffles only consider the problem of blocking liquid from flowing to a suction port, and do not consider the problem of resistance when gas flows.
Chinese patent 2015203641568 discloses a flooded evaporator and an air conditioning unit, the flooded evaporator comprises a shell and a heat exchange tube arranged in the shell, the top wall of the shell is provided with an air suction port, the bottom wall of the shell is provided with a liquid inlet, a shielding component for blocking gas containing liquid is arranged above the heat exchange tube, the shell is also internally provided with a supporting component, the shielding component and the heat exchange tube are connected with the supporting component, and a gap for the gas containing liquid to pass through is reserved between the two ends of the shielding component along the length direction of the shell and the inner wall of the shell respectively; the shielding component is connected with the inner side wall of the shell in a sealing mode along the two sides of the width direction of the shell. By adopting the flooded evaporator, the resistance loss of the air suction side of the evaporator can be reduced under the condition that the compressor of the air conditioner cannot generate liquid compression, so that the energy is saved, the service life of equipment is prolonged, and the flooded evaporator is more reliable in use.
The above patent only carries out gas-liquid separation through a shielding part and the baffle of breathing in that sets up in suction opening department, and the effect of separation is poor, still can appear that excessive liquid refrigerant too late to become saturated steam, just gets into the compression chamber, causes the condition of "liquid compression".
