Description
Technical field
The utility model relates to the evaporimeter in a kind of refrigeration air-conditioner heat-exchange system, especially a kind of vertical type evaporator with gas-liquid separating function.
Background technology
Generally in the refrigeration air-conditioner heat-exchange system, all need to comprise evaporimeter, condenser and compressor and pipe-line system etc., cold-producing medium circulates in pipe-line system, be condensed into liquid state by after the compressor compresses, and emit heat, in evaporimeter, absorb heat after the liquid cold-producing medium throttling and turn to gaseous state, the cold-producing medium of gaseous state enters into to be compressed once more behind the compressor and is condensed into liquid state, and so circulation is to realize the transfer and the exchange of heat.In this existing refrigeration air-conditioner heat-exchange system, the air conditioner compressed refrigeration system of ammonia refrigeration particularly, need avoid refrigerant liquid to enter described compressor and cause performance of refrigerant systems to reduce, even compressor is broken down, cisco unity malfunction by air entry.In the prior art, be to adopt independent gas-liquid separation device to carry out the gas-liquid separation of cold-producing medium.Existing gas-liquid separation device volume is big, not only can occupy bigger space, and the filling quantity of refrigerant of refrigeration system is improved, and has increased equipment cost simultaneously.
The utility model content
At above-mentioned the deficiencies in the prior art, technical problem to be solved in the utility model is, how to design a kind of vertical type evaporator, and then reduce filling quantity of refrigerant, occupation of land volume and the equipment cost of the refrigeration system of whole heat-exchange system with gas-liquid separating function.
In order to solve the problems of the technologies described above, adopted following technical scheme in the utility model:
A kind of vertical type evaporator with gas-liquid separating function comprises a housing, and its characteristics are that described housing center vertically is provided with central tube, and the central tube below passes housing and is set to the liquid refrigerant inlet; Correspondence is provided with the gaseous refrigerant outlet on the housing of top, central tube upper end open place; Described enclosure interior is divided into the cold-producing medium liquid zone of bottom, heat of evaporation exchange area and superposed gas-liquid separation zone between two baffle plates by horizontally disposed two baffle plates with the housing inner chamber, lower end, described cold-producing medium liquid zone is provided with oil export, and described gaseous refrigerant outlet is positioned at the gas-liquid separation zone top; Vertical sealing is provided with some evaporation heat transfer pipes that are communicated in gentle liquid Disengagement zone, cold-producing medium liquid zone between described two baffle plates, and the housing of described heat of evaporation exchange area sidewall is provided with heat exchange medium inlet and heat exchange medium exit.
When this vertical type evaporator uses, liquid cold-producing medium enters in the central tube and from the central tube upper end open from the liquid refrigerant inlet and enters into the housing inner chamber, flow to the cold-producing medium liquid zone of bottom under the down-comer of liquid refrigerant through being provided with, enter then in the evaporation heat transfer pipe of heat of evaporation exchange area.The evaporation heat transfer pipe outside of heat of evaporation exchange area has from the heat exchange medium (can be water) of heat exchange medium inlet and heat exchange medium exit circulation, heat exchange medium is with the liquid refrigerant in the heat transferred evaporation heat transfer pipe and make its evaporation, and the liquid refrigerant evaporation is also taken away the heat that heat exchange medium has; The gas-liquid cold-producing medium enters and carries out gas-liquid separation in the gas-liquid separation zone, gaseous state is sent housing from refrigerant outlet, simultaneously, in the process of heat exchange, fluid in the cold-producing medium liquid zone of bottom is because the proportion difference, lubricating oil can sink automatically and enter in the oil catcher of housing bottom, sends housing from the oil catcher outlet at last.
As further optimization, also be provided with the heat pipe evaporator section structure between described central tube upper end open place and the gaseous refrigerant outlet, the heat pipe evaporator section structure comprises some between the upper and lower every the fin that is provided with, fin integral body is arranged ringwise, heat pipe evaporator section structure below be fixedly connected with one extend down into along central tube inside the heat of evaporation exchange area heat pipe, described heat pipe lower end closed is provided with.Like this, gas-liquid cold-producing medium in the gas-liquid separation zone can pass through the heat pipe evaporator section structure before entering into the gaseous refrigerant outlet, so some droplets can stop attached on the fin of heat pipe evaporator section structure and absorb heat and be evaporated to gas, help improving the security of heat exchange efficiency and refrigeration system.Evaporator section comes from the heat pipe that is inserted into central tube inside for the heat that droplet absorbs, because the heat pipe lower end is positioned at the heat of evaporation exchange area, can absorb the preceding higher liquid refrigerant heat of temperature of throttling.
In sum, vertical type evaporator of the present utility model has the function of gas-liquid separation, adopts the heat-exchange system of this evaporimeter, need not additionally to be provided with gas-liquid separation device, so reduce occupation of land volume, filling quantity of refrigerant and the equipment cost of whole heat-exchange system.Simultaneously, vertical type evaporator of the present utility model also has the high advantage of heat exchange efficiency.
