Abstract
The utility model discloses a special water cooled chiller unit at the tail end of a capillary network, which comprises a semi-closed screw compressor. An outlet of the semi-closed screw compressor is communicated with an inlet of a shell-tube condenser, an outlet of a shell-tube condenser is communicated with a flooded evaporator through a drying filter drum and an electronic expansion valve, an outlet of the flooded evaporator is communicated with an inlet of the compressor, the shell-tube condenser is provided with an internal oil separator, an outlet of the oil separator is communicated with an inlet of a powerless oil return device, an outlet of an unpowered oil return device is connected in series to a pipeline between the inlet of the compressor and the outlet of the flooded evaporator, an ejector is arranged in the unpowered oil return device, and an ejection port of the ejector is communicated with an oil outlet of an oil storage tank of the flooded evaporator through a ball valve. The special water cooled chiller unit has the advantages of simple structure of system pipelines, convenience in control, high evaporation temperature, evident energy saving effect, and capability of being adjusted according to practical load conditions so as to match operation capacity with practical load.
Description
Technical field
The utility model relates to source pump, especially relates to the cold water unit of the terminal dedicated water of a kind of capillary network.
Background technology
Raising along with China's rapid economic development and living standards of the people, people improve constantly the requirement of indoor comfort, but what bring is that energy-output ratio is increasing thereupon, causes the day of energy resource supply to be becoming tight the comfortable and energy-conservation hot issue that becomes social concerns.40%～50% of the whole energy consumptions of building energy consumption account China, wherein most of energy consumption from air-conditioning systems such as family and office spaces, updating and innovating of heating and refrigeration modes will be energy-conservation key point.On the other hand, traditional handpiece Water Chilling Units is used and surveyed the Inlet and outlet water temperature is 12/7 ℃, and evaporating temperature is 2 ~ 5 ℃, and evaporating temperature is low, and wasted work is bigger, develops more energy-conservation handpiece Water Chilling Units and arises at the historic moment.
Summary of the invention
The purpose of this utility model is to provide the terminal dedicated water of high energy-conservation capillary network in a kind of capillary network air-conditioning system cold water unit.
For achieving the above object, the utility model can be taked following technical proposals:
The cold water unit of the terminal dedicated water of capillary network described in the utility model, comprise the semi-closed screw type compressor, the outlet of described semi-closed screw type compressor is connected with the shell and tube condenser import, the outlet of described shell and tube condenser is connected with flooded evaporator by dry filter tube and electric expansion valve, and the outlet of described flooded evaporator is connected with the import of compressor; In described shell and tube condenser, be built-in with oil eliminator, the outlet of described oil eliminator is connected with the import of unpowered oil return apparatus, the outlet of described unpowered oil return apparatus is connected on the pipeline between the outlet of compressor inlet and flooded evaporator, be provided with injector in unpowered oil return apparatus, the ejecting port of described injector is connected by the oil-out of ball valve with the flooded evaporator oil storage tank.
Be the pipeline of two parallel connections in the described unpowered oil return apparatus, article one pipeline is in series with magnetic valve and flow controller by inlet to outlet; The second pipeline is in series with magnetic valve, injector and hand valve by inlet to outlet.
The utility model advantage is that system pipeline is simple in structure, control is convenient, evaporating temperature is high, energy-saving effect is remarkable, unit can be regulated according to the actual loading situation, makes working capacity and actual loading coupling.The Inlet and outlet water temperature of using the utility model to measure is 21/18 ℃, evaporating temperature is 16 ℃, and high energy-conservation because of its evaporating temperature, its coefficient of performance COP can reach 7.0, use the same model compressor refrigerating capacity can increase more than 80% than traditional handpiece Water Chilling Units, the coefficient of performance improves more than 65%.Produce same refrigerating capacity, the cold water unit operation of the terminal dedicated water of capillary network expense can reduce by 30% ~ 40%, thereby initial cost that can corresponding reduction unit equipment reduces the waste of the energy.
