The system has smaller structural size and high heat exchange efficiency.

Description

A kind of air-conditioning system
Technical field
The present invention relates to air-conditioning system more particularly to SPLIT AIR-CONDITIONING SYSTEMs.
Background technique
Existing split type refrigerant air-conditioning system includes indoor unit and outdoor unit, and outdoor unit includes compressor, condenser etc. Component, indoor unit include the components such as evaporator, blower, and refrigerant passes through indoor machine evaporation and blower after outdoor unit is cooling Heat exchange refrigeration is carried out with air, declines temperature in room.
This air-conditioning system causes indoor unit to take up space greatly, while room since the component necessary parts of indoor unit are more The motor noise of interior machine is also big, influences house comfort level.
In addition, split type coolant system there must be indoor unit and outdoor unit, set of system could be become, cause manufacturing cost higher, And must be connected with refrigerant pipe inside and outside most of split type system chambers, and secondary refrigerant leakage be easy to cause safety to ask with environment Topic.
Summary of the invention
In order to solve the above-mentioned problems in the prior art, the invention proposes a kind of air-conditioning systems, including vapour pressure Compression type refrigerating component, the air compression assembly being connected to by air return pipeline with each room are connected to each room air outlet and air-supply Air expansion assembly between pipeline;Air in room compressed by the air compression assembly after with steam compression type refrigeration Component exchanges heat, then expands by air expansion assembly while residual compression is converted into aerodynamic energy and return to each room.
In one embodiment, the air compression assembly includes compressor.Preferably, the air compression assembly also wraps The pressure sensor for including pressure in measurement air supply pipeline, the signal for receiving the pressure sensor carry out frequency control to compressor Control makes the control module that pressure is constant in air supply pipeline.
In one embodiment, the air expansion assembly includes the nozzle with venthole.Preferably, the air expansion Component includes the moving component of the pore size and hole number for adjusting venthole.
Preferably, the internal diameter of the air supply pipeline is less than the internal diameter of same shape air hose.The air supply pipeline uses water pipe It is laid with.
In one embodiment, the steam compression type refrigeration component is set to outdoor unit.In another embodiment, described The heat exchanger to exchange heat in steam compression type refrigeration component with compressed air is set in each room, and remaining part is set to outdoor Machine.The steam compression type refrigeration component of the two embodiments includes the compressor to form closed loop, condenser, throttle valve, steaming Device and gas-liquid separator are sent out, is condenser or evaporator with the heat exchanger that compressed air exchanges heat.
The present invention uses air expansion air-conditioning system, will exchange heat again after supercharging air, improves heat exchange efficiency, then exist Expansion structure is set at air outlet, makes pressure-air in conjunction with expansion structure, while realizing refrigeration and air-supply effect, and blow Due to being pressure-air in pipeline, it is possible to reduce space utilization rate is improved in air-supply air hose space.
Detailed description of the invention
Below with reference to embodiment and attached drawing, the present invention is described in detail, wherein:
Fig. 1 is a preferred embodiment of the invention.
Specific embodiment
As shown in Figure 1, air-conditioning system of the invention by conventional steam compression type refrigeration component and air compression assembly and Air expansion assembly combines composition.Air compression assembly is connected to by air return pipeline 9 with each room 11, the connection of air expansion assembly Between each 11 air outlet of room and air supply pipeline.
By taking air conditioner refrigerating as an example, gaseous coolant passes through after compressor 1 compresses at high-pressure gaseous refrigerant, after condenser 2 As high-pressure liquid refrigerant, become low pressure liquid-vapor mixture by throttle valve 3, then be flowed into the evaporation of evaporator 4, in evaporator 4 Refrigerant and the compressed high temperature air of compressor 6 exchange heat, then are then return to the circulation of compressor 1 by gas-liquid separator 5.Room 11 Interior air passes through air return pipeline 9(Low pressure)It is sent to air compression assembly, air is compressed into high temperature sky by air compression assembly After gas, then by being high pressure low temperature air with the heat exchange cooling of evaporator 4, then pass through air supply pipeline 7(High pressure)It is distributed to Each room 11, then expanded by air expansion assembly, while residual compression is converted into aerodynamic energy from each room 11 It is blown out at air outlet, Cryogenic air is mixed with space air reduces temperature in room, reaches cooling refrigeration effect.The present embodiment Air supply pipeline 7 is pressure-air due to transport, it is thereby possible to select internal diameter is less than the pipeline of same shape air hose, or even can To replace using suitable water pipe, the cost of system is reduced.
Air expansion assembly in the present embodiment, including the nozzle 8 with venthole, can also further include one and be used for The pore size of venthole and the moving component of hole number are adjusted, changes 8 alternation of cross-section outlet air of nozzle by moving component Pressure, and increase air inducing mixed-flow structure and change indoor circulation air quantity.Nozzle arrangements those skilled in that art can refer to can The first-class existing structure of shower spraying for changing nozzle cross-section and apopore size, is also designed to the movement portion of automatic control and adjustment Part.
Air compression assembly is in the present embodiment using compressor 6.In other embodiments, it may further send Setting measures the pressure sensor of its interior pressure in air pipe line, and the letter of pressure sensor is then received by a control module Number, variable frequency regulating speed control is carried out to compressor 6, keeps pressure in air supply pipeline constant.
In the embodiment shown in fig. 1, entire steam compression type refrigeration component is respectively positioned in outdoor unit 10, and interior is only There are nozzle and air outlet, does not need that interior machine is arranged, therefore occupied space is smaller, system cost is low.Since refrigerant is entirely located in room Outer machine 10, the only air entered the room, therefore the risk of secondary refrigerant leakage is also not present, it is a more excellent implementation of the invention Example.In other embodiments, those skilled in the art the heat exchanger to exchange heat with high pressure-temperature air can be arranged In indoor unit indoors, remaining component of steam compression type refrigeration component is still arranged in outdoor unit 10, needs to set in this way It sets one and is compared to the lesser interior machine of prior art size, also belong in protection scope of the present invention.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
