Description
Technical field
The present invention relates to technical field of heat exchange more particularly to a kind of heat-exchange system multistage series-parallel connection replacement modules.
Background technology
Such as Fig. 1, traditional air conditioner and heat pump heating/refrigeration system include compressor, condenser, throttling element and evaporator,
Low-temp low-pressure working medium in heating/cooling system flows through evaporator and absorbs heat gasification, is compressed to high temperature and pressure within the compressor
Liquid, flow through condenser release heat be cooled to highly pressurised liquid, be finally again introduced into evaporator after throttling element is depressured.Working medium
Constantly heat absorption, heat release, realizes system heating/refrigeration in cyclic process in system.Above-mentioned heating/refrigeration system is in outdoor
Under the operating mode of low temperature, especially when required condensation temperature is relatively high, heating capacity decaying is extremely serious, or even can not normally start
Operation.
Condenser is installed in the environment for needing to heat, working medium is in evaporator by heating/refrigeration system when for heating
The middle heat absorbed in evaporator local environment, and be delivered in condenser through working medium runner and discharge heat, to improve condenser
The temperature of local environment, reaches heating effect.Evaporator is installed on when for freezing and needs to freeze by heating/refrigeration system
Environment in, working medium absorbs the heat in evaporator local environment to reduce the temperature of evaporator local environment in evaporator,
And be delivered in condenser through working medium runner and the heat being absorbed into is discharged into the environment residing for condenser, reach refrigeration effect
Fruit.
As shown in Fig. 2, the application scenarios of traditional air conditioner and heat pump refrigerating/heating system are divided for two regions：Work
Matter discharges the condensing zone of heat and working medium absorbs the evaporating area of heat, in practical application place between condensing zone and evaporating area not
It is isolation, their mutual temperature are gradual changes, can be by condensing zone and steaming there is no an apparent temperature limit
Hair zoning separates.Condensed device come out high temperature and pressure working medium before non-total condensation can in the form of gas-liquid two-phase state into
Enter throttling element, while condensing zone heat dissipation capacity is reduced, the throttle efficiency of strong influence throttling element, due to entering evaporating area
Can evaporated liquid working medium amount reduction and matter decline, and then influence the heat absorption efficiency of evaporating area evaporator so that entire heating/
Heating/refrigerating capacity of refrigeration system is had a greatly reduced quality.
If application publication number is CN 101165438, the application for a patent for invention that data of publication of application is on 04 23rd, 2008 is public
A kind of super low temperature heat pump air conditioner system is opened.The system includes compressor, main throttle part, indoor external heat exchanger, gas-liquid separation
Device, four-way valve, solenoid valve are connected by pipeline between each parts；The system also includes an at least flasher components, institutes
The outlet for stating flasher components is connected by pipeline with the air entry of the compressor.Using enhanced jet screw compressor
And steam injection system.In worst cold case heating operation, using flash vessel ejector refrigeration agent, keep the sucking of compression function more
Refrigerant realizes quasi- Two-stage Compression, improves heating capacity and Energy Efficiency Ratio, while keeping lower compression ratio and delivery temperature again, empty
Adjust stable and reliable operation.But due to increasing enhanced jet screw compressor and vapor injection system in the air-conditioning system,
Cost of manufacture greatly improves, and the energy consumption that entire air-conditioning system needs when running also greatly increases.And in extreme environment, being
The usage comfort of user is improved, we more want to environment temperature are adjusted to needs in the time short as possible
Target temperature.Amount by increasing the refrigerating/heating working medium recycled in heating/refrigeration system can improve a refrigerating/heating
The amount of heat carrier in cyclic process, to improve the refrigerating/heating efficiency of system.But the heat pump air conditioning system is in work
Quality easily leads to compressor and vapor injection system overload operation when increasing.Most importantly in preceding solution
In, during working medium flows to evaporating area by condensing zone, the loss of working medium Quantity of heat still has, entire heating/refrigeration system
The energy of system it is total some can waste in this process so that the efficiency of heating/refrigeration system is unable to reach optimal.
