Description
Technical field
The utility model relates to air conditioner refrigerating technical field, is particularly suitable for water-cooled cold water/source pump that riverboat is used.
Background technology
In the various ships of inland waterway navigation, air-conditioning and refrigerating plant have obtained extensive application as a part for marine auxiliary, and it is mainly used in providing comfortable human settlement and the needs of food product refrigeration.Because boats and ships are subject to the impact of stormy waves when the surface navigation of inland river, there will be the situations such as periodically rolling, pitching, long-term heel, trim.Compressor in unit there will be the oily phenomenon of mistake when boats and ships rock, and affects unit and normally moves.In order to guarantee that air-conditioning and refrigerating plant normally move, what the marine air conditioner of prior art and refrigerating plant evaporimeter used adopted is all air cooling fin cast, dry pipe shell type evaporimeter, but uses and increased energy consumption like this, sacrifice be the efficiency of unit.In recent years, due to the requirement of energy prices rise and energy-saving and emission-reduction, reduce boats and ships energy consumption and become a urgent job, air-conditioning equipment energy consumption accounts for a big chunk ratio of the whole energy consumption of boats and ships, therefore improves air-conditioning unit efficiency and is significant.
Summary of the invention
For above-mentioned problems of the prior art, the purpose of this utility model is to provide a kind of water-cooled cold water/source pump that riverboat is used that is suitable for.It adopts flooded evaporator to reduce units consumption, improves unit operation efficiency, and guarantees that unit each several part can normal stable operation.
In order to reach foregoing invention object, the technical solution of the utility model realizes as follows:
Be suitable for water-cooled cold water/source pump that riverboat is used, it comprises helical-lobe compressor, condenser, device for drying and filtering, liquid-sighting glass, expansion valve and the evaporimeter connecting successively.Its design feature is, described evaporimeter adopts flooded evaporator, and the oil return opening of flooded evaporator is placed in its 10 degree positions on the lower side, tank body center, and the oil return pipe of flooded evaporator is connected to the inlet ductwork of helical-lobe compressor.Between helical-lobe compressor and condenser, connect high-efficiency oil separator, the oil return pipe of high-efficiency oil separator is connected to the inlet ductwork of helical-lobe compressor.Helical-lobe compressor below is equipped with external fuel reserve tank and is connected with the oil feeding line of helical-lobe compressor.Condensator outlet adopts two-way feed pipe fluid.
The utility model, owing to having adopted said structure, has been used the flooded evaporator of high energy efficiency, effectively reduces units consumption, improves unit operation efficiency.During due to the work of hydraulic filling type water-cooling cold water/source pump, can reach higher evaporating temperature; in the situation that condensation temperature is identical; compare and adopt the water-cooled cold water/source pump of dry evaporator can reach higher coefficient of performance; and then relatively saved the operating cost of unit; reduced the operating cost of boats and ships; also reduce boats and ships to the pollutant discharge amount of atmosphere on the way simultaneously, protected environment.The utility model also, by compressor fuel reserve tank being set, selecting high-efficiency oil separator and optimize flooded evaporator oil return opening and condenser fluid pipeline, has guaranteed water-cooled cold water/source pump whenever can normally work in ship's navigation.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the oil return opening position view of the utility model flooded evaporator.
The specific embodiment
Referring to Fig. 1 and Fig. 2, the utility model comprises helical-lobe compressor 1, high-efficiency oil separator 2 condensers 3, device for drying and filtering 4, liquid-sighting glass 5, expansion valve 6 and the evaporimeter connecting successively.Evaporimeter adopts flooded evaporator 7, and the oil return opening of flooded evaporator 7 is placed in its 10 degree positions on the lower side, tank body center, and the oil return pipe of flooded evaporator 7 is connected to the inlet ductwork of helical-lobe compressor 1.The oil return pipe of high-efficiency oil separator 2 is connected to the inlet ductwork of helical-lobe compressor 1.Helical-lobe compressor 1 below is equipped with external fuel reserve tank 2 and is connected with the oil feeding line of helical-lobe compressor 1, and condenser 3 outlets adopt two-way feed pipe fluid.
During the utility model work, the oil feeding line of helical-lobe compressor 1 first accesses the oil circuit import of helical-lobe compressor 1 from the oil circuit outlet of helical-lobe compressor 1 bottom is drawn again through fuel reserve tank 8, thereby guarantee that helical-lobe compressor 1 there will not be the oily phenomenon of mistake when boats and ships rock, and guarantees that unit normally moves.High-efficiency oil separator 2 can further reduce the oil shortage ratio of refrigerant vapour, reduces as far as possible the lubricants capacity that enters flooded evaporator 7.Condenser 3 adopts two-way fluid, has guaranteed that helical-lobe compressor 1, also can steady and continuous feed flow in the situation that of boats and ships generation trim.The oil return opening of flooded evaporator 7 is placed in 10 degree positions on the lower side, tank body center, can adapt to ship's navigation feature, guarantees that flooded evaporator 7 can normal oil return in most times of unit work.
For common semiclosed screw flooded water-cooled cold water/source pump for land, oil circuit blocking-up pin only need be installed on helical-lobe compressor 1, by pipeline, be connected with fuel reserve tank 8 simultaneously, the extreme higher position of fuel reserve tank 8 will be lower than the extreme lower position of helical-lobe compressor 1.Between helical-lobe compressor 1 and condenser 3, install external high-efficiency oil separator 2 additional, oil eliminator import is connected with helical-lobe compressor 1 exhaust outlet, condenser 3 air inlets are connected with high-efficiency oil separator 2 outlets, high-efficiency oil separator 2 oil return openings access helical-lobe compressor 1 suction side by pipeline, by air-breathing helical-lobe compressor 1. condensers 3 of taking back, adopt two-way fluid pipeline, in condenser 3 outsides, converge into again road direction flooded evaporator 7 feed flows; According to boats and ships navigating area and the swing angle of boats and ships own, optimize flooded evaporator 7 oil return opening positions, guarantee the most of the time, flooded evaporator 7 has oil to get back to helical-lobe compressor.
