Abstract
The utility model provides a multi-split air conditioner which includes a outdoor unit, a indoor unit and a refrigerant flow distributor of a refrigerating machine, the refrigerant flow distributor includes a outdoor unit refrigerant pipe, a filter, the electronic expansion valves and a computer control board; the outdoor unit refrigerant pipe splits are the refrigerant branch pipelines which connects the a plurality of the air-conditioner indoor units, the electronic expansion valves is provided at the refrigerant branch pipelines out of the indoor units. Usually, each electronic expansion valve at the refrigerant branch pipeline is provided near the outdoor unit refrigerant pipe splits, the electronic expansion valves and the outdoor unit refrigerant pipe splits are arranged inside the case; the indoor unit of the air-conditioner has little running noise, and inspection and repair are very convenient.
Description
Affiliated technical field
The utility model relates to a kind of air-conditioner, is specifically related to a kind of multi-split air conditioner.
Background technology
Multi-split air conditioner generally includes an off-premises station, in off-premises station, be provided with compressor, refrigerant after compressor will compress is shunted to many refrigerant branch lines by off-premises station liquid pipe, the refrigerant branch line links to each other with a plurality of air conditioner room units, branch line is provided with electric expansion valve, electric expansion valve carries out throttling control to refrigerant, control by throttling, refrigerant in indoor set in the evaporimeter makes the surrounding air refrigeration, by fan with blow cold air to indoor, indoor temperature is regulated.Because off-premises station of multi-split air conditioner can drive a plurality of indoor sets, and is simple in structure, save the space, therefore dark receipts consumer likes.In the existing multi-split air conditioner, electric expansion valve is provided with in the indoor apparatus of air conditioner, the air conditioner room unit complex structure, and the air conditioner room unit inconvenient maintenance, and electric expansion valve is arranged on increased the operation of indoor set noise in the indoor set.
Summary of the invention
The utility model has overcome the electric expansion valve of existing multi-split air conditioner owing to be arranged in the indoor machine of air-conditioner, increase air-conditioner operation noise, the shortcoming of air-conditioner maintenance inconvenience provides a kind of multi-split air conditioner, this air conditioner room unit operation noise is little, and maintenance is convenient.
The utility model discloses a kind of multi-split air conditioner, comprise off-premises station, indoor set and refrigeration machine refrigerant flow distributor, wherein the refrigeration machine refrigerant flow distributor comprises off-premises station liquid pipe, filter, electric expansion valve and computer control panel, off-premises station liquid pipe is shunted to many refrigerant branch lines that link to each other with a plurality of air conditioner room units, on the refrigerant branch line electric expansion valve is set, it is characterized in that: described electric expansion valve is arranged on the refrigerant branch line outside the described indoor set.
In the technique scheme, owing to electric expansion valve is arranged on the refrigerant branch line in addition of air conditioner room unit, the operation noise of air-conditioner is little, the indoor apparatus of air conditioner designs simplification, when air conditioner room unit produces fault, maintenance is convenient, and when electric expansion valve produced fault, same maintenance was convenient.
Electric expansion valve need be fixed on the ad-hoc location after being arranged on the air conditioner room unit refrigerant branch line in addition usually, and for making sub-expansion valve easy for installation, the electric expansion valve on described each refrigerant branch line is concentrated and is arranged in the separate unit usually.
Common described electric expansion valve is located to be provided with near off-premises station liquid pipe along separate routes, and described liquid pipe is located to be arranged in the described separate unit along separate routes.
For shunt place of electric expansion valve and off-premises station liquid pipe being played protection and insulation effect, common described separate unit is a casing.
Be provided with electric expansion valve computer control panel in the multi-split air conditioner.After being arranged on electric expansion valve outside the indoor apparatus of air conditioner, described computer control panel is arranged on the described casing in the utility model.
Common described computer control panel is arranged on the outer wall of described casing.Described computer control panel is arranged in the computer control panel casing.
Common described filter be arranged on that off-premises station liquid pipe is located along separate routes and electric expansion valve between the refrigerant branch line on.
Indoor clean and tidy and easy to maintenance when electric expansion valve breaks down for making, common described casing is near the off-premises station setting.
The further preferred version of described casing setting is: described casing is arranged on the off-premises station.
In the utility model, electric expansion valve is arranged on outside the air-conditioner outdoor unit, the operation noise of air conditioner room unit further reduces, the air conditioner room unit designs simplification, and air conditioner room unit is easy to maintenance.Because electric expansion valve is provided with separately, flexible for installation simple, maintenance was same convenient when electric expansion valve broke down.
Description of drawings
Fig. 1 is a multi-split air conditioner refrigeration machine refrigerant flow distributor specific embodiment structural representation.
The specific embodiment
A kind of multi-split air conditioner, comprise off-premises station, indoor set and refrigeration machine refrigerant flow distributor, wherein the refrigeration machine refrigerant flow distributor comprises off-premises station liquid pipe 1 and electric expansion valve computer control panel etc., off-premises station liquid pipe 1 is from locating 40 is divided into 3 tunnel refrigerant branch lines that link to each other with air conditioner room unit 2,3,4 along separate routes, electric expansion valve 5,6,7 is set respectively on the refrigerant branch line 2,3,4, and electric expansion valve 5,6,7 and refrigerant are located on the branch line between 40 filter 8,9,10 to be set along separate routes.Off-premises station liquid pipe locates 40 along separate routes, filter 8,9,10 and electric expansion valve 5,6,7 are arranged in the casing 20.
In the above-mentioned specific embodiment, after the compressed machine compression of refrigerant, enter off-premises station liquid pipe 1, locate 40 in shunt and be divided into 3 road refrigerant branch lines 2,3,4, after refrigerant filters through filter 8,9,10 respectively, respectively by electric expansion valve 5,6,7 throttlings control, the evaporimeter by separately freezes to surrounding air.
Because electric expansion valve is arranged in the casing 20, air conditioner room unit operation noise reduces, and air conditioner room unit is easy to maintenance, and casing 20 makes electric expansion valve flexible for installation easy, makes electric expansion valve easy to maintenance simultaneously.
