Abstract
The utility model relates to a water source heat pump unit with a drip type evaporator. The problem to be solved is the problem existed in the background technology, more specifically, the evaporator in the water source heat pump unit is the dry type or the flooded type evaporator, the refrigerant in the dry type evaporator flows in the tube side and the secondary refrigerant (water) flows in the shell side. Although the refrigerant charge is relatively little, the consumption of the atmospheric ozone layer is little, but the heat transfer efficiency is low and the energy consumption is high. For the flooded type evaporator, the refrigerant flows in the shell side, although the heat transfer efficiency is high, but the refrigerant charge is more, the refrigerant is Freon which can consume the atmospheric ozone layer and have the global warming effect. The key point of the technical proposal to solve the technical problem is that the cylinder of the evaporator is equipped with a refrigerant dripping device evenly distributed with the small holes. The utility model can be applied in the fabrication and the application of the water source heat pump unit and has the remarkable advantages of the energy conservation and the environmental protection.
Description
Technical field:
The utility model belongs to a kind of water source heat pump units, particularly a kind of water source heat pump units that adopts the dripping type evaporimeter.
Background technology:
The basic structure of existing water source heat pump units is: be formed by connecting by pipeline by compressor, condenser, filter, choke valve, evaporimeter, jet pump; In the cylindrical shell of evaporimeter heat exchanger tube is set, heat exchanger tube is arranged on the tube sheet, and the cylindrical shell two ends are provided with end socket, and muffler and feed tube also are set on the cylindrical shell.Wherein evaporimeter is dry type or flooded evaporator, and the dry evaporator cold-producing medium flows at tube side, refrigerating medium (water) flows at shell side, though refrigerant charge is less relatively, it is also less to consume atmospheric ozone layer, and its heat transfer efficiency is low, increases energy consumption.And the flooded evaporator cold-producing medium flows at shell side, though the heat transfer efficiency height, refrigerant charge is big, and this cold-producing medium is fluorine Lyons working medium, and it consumes atmospheric ozone layer and the effect that makes global warming is arranged.
Summary of the invention:
The purpose of this utility model is exactly to propose a kind of technical scheme that adopts the water source heat pump units of dripping type evaporimeter, exist with the solution background technology: in the water source heat pump units, the dry evaporator cold-producing medium flows at tube side, refrigerating medium (water) flows at shell side, though refrigerant charge is less relatively, it is also less to consume atmospheric ozone layer, but its heat transfer efficiency is low, increases energy consumption; And the flooded evaporator cold-producing medium flows at shell side, though the heat transfer efficiency height, refrigerant charge is big, and this cold-producing medium is fluorine Lyons working medium, and it consumes atmospheric ozone layer and the effect that makes global warming is arranged.Solving this technical problem the technical scheme that is adopted is: a kind of water source heat pump units that adopts the dripping type evaporimeter is formed by connecting by pipeline by compressor, condenser, filter, choke valve, evaporimeter, jet pump; In the cylindrical shell of evaporimeter heat exchanger tube is set, heat exchanger tube is arranged on the tube sheet, and the cylindrical shell two ends are provided with end socket, and muffler and feed tube also are set on the cylindrical shell, it is characterized in that the cold-producing medium that uniform aperture is set in the evaporator tube drips shower device.
The beneficial effect that the utility model is had compared with the prior art is: owing to adopt technique scheme, tube side is for planting cryogen (water), shell side is a cold-producing medium, cold-producing medium is set in the cylindrical shell to drip shower device and drips the cold-producing medium that drenches, evenly the cold-producing medium drop of supply vertically drips and drenches to the heat exchanger tube surface, most of liquid refrigerant explosive evaporation is a saturated gas, gas is taken pipe battle array outside out of along gas flow, be collected to the suction side that sucks back compressor behind the cylinder top, the liquid refrigerant that small part is not evaporated, with regard to productive set in cylindrical shell bottom, form and the similar fluidized state of flooded evaporator.Therefore, the utility model is compared with flooded evaporator, and most of liquid refrigerant drips and drenches in the evaporation of evaporimeter heat exchanger tube surface boiling, and the unevaporated liquid refrigerant of fraction comes together in the cylindrical shell bottom, forms and the similar fluidized state of flooded evaporator.The high heat transfer efficiency that had both had flooded evaporator reduces charging amount, the reduction initial cost of cold-producing medium again, and reduces the consumption of atmospheric ozone layer and avoid global warming; Compare with dry evaporator again; owing to have the fluidized state of full liquid evaporimeter; its heat transfer efficiency is higher than dry evaporator, the problem that the heat transfer efficiency that has solved dry evaporator so well is low, the flooded evaporator refrigerant charge is big, and help environmental protection.
