Abstract

Disclosed is an external circulation concentrative water cold type central air conditioner which is composed of two or more indoor units 1 and an outdoor unit 2 that are connected together, the indoor unit mainly comprises a refrigerating system which is composed of compressor 3, condenser 4, capillary 5, evaporator 6 and pipeline 7 that are connected circularly. The utility model is characterized in that two sets of refrigerating systems are provided; the starting circuit of a certain compressor is provided with a starter 10; the outdoor unit is an air-cold radiator and is respectively connected with water inlet and outlet tubes 8 and 9 of each condenser. As the indoor unit is provided with a small compressor, manufacture cost can be reduced greatly under the condition of same power; as the starting circuit of a certain compressor is provided with a starter so that two compressors start respectively so as to lower the starting current and electric load, and the high requirement of electric wire of appliance; As the outdoor unit is also an air-cold radiator, the outdoor unit has good radiating effect and small size, and can improve the radiating efficiency and prevent the large amount of radiators from being hung outdoors.

Description

A kind of water-cooled residential central air-

Affiliated technical field

The utility model relates to a kind of water-cooled residential central air-, especially relates to a kind of employing outer circulation and concentrates water-cooled family central air-conditioning.

Background technology

Along with improving constantly of people's living standard, people also improve the requirement of living thereupon, and the function distinguishing in room is also more and more thinner, are separated with between common: master bedroom, guest bedroom, children room, study, parlor, dining room etc., and also area is also increasing.So, how to select, install, use air-conditioning more rightly, with regard to the problem that has become people to consider.Existing various air-conditioning such as window machine, split air conditioner etc., though install and use all easily, these all are split air conditioners, and it comprises indoor set and off-premises station, the air-conditioning in every chamber makes the open air " overwork " off-premises station, and not only having influence on the city beauty has also increased more factor leading to social instability simultaneously; Why like this, be because the structure of separate type air conditioner institute extremely: it comprises indoor set and off-premises station existing separate type air conditioner, mainly link to each other with the pipeline circulation and constitute by a compressor, condenser, capillary, evaporimeter etc., the air conditioner of each chamber all is independently, and the result causes the open air " to overwork " phenomenon of off-premises station; They are two years old, because floor space is big, required air-conditioning power is also big, and the ratio of the price of air-conditioning and power is not simple linear, additive, for example 1.5 compressor price is about 400 yuan, and 3 compressor price modification lattice then are about 1000 yuan, and the starting current of 3 compressors is big, be about five times of normal current, electrical equipment electric wire etc. has been proposed high request; Though and if adopt the words of frequency-changeable compressor to regulate compressor rotary speed according to the running load and the operational situation of air-conditioner, its price is also high, for example 3 frequency-changeable compressor price then is about 1300 yuan, but frequency converter is with regard to 1500 yuan of offers.

The building that for this reason has is forbidden outdoor on-hook and is used the large-scale central air-conditioning of central cooling heat supply type, but cost is too high again and utilization rate is lower.

The utility model content

The purpose of this utility model just provides the water-cooled residential central air-that a kind of starting current is low and cost is high, capable of reducing energy consumption, not convenient and practical yet.

For achieving the above object, water-cooled residential central air-of the present utility model is made up of the outer machine of indoor set junction chamber, indoor set mainly comprises shell body and interior being made up of with the continuous refrigeration system that constitutes of pipeline circulation compressor, condenser, capillary, evaporimeter etc. thereof, and it is characterized in that: described refrigeration system has two covers; At a certain machine start-up circuit that contracts the delayed startup device is arranged; Described off-premises station is an air-cooled radiator, and it has water inlet pipe and water outlet pipe to link to each other with two condensers.

On the basis of the above, the utility model also can be done further improvement:

With two or the above shared off-premises station of indoor set.

The beneficial effects of the utility model are: because indoor set has i.e. two light duty compressors of two cover refrigeration systems, when requiring to reach same power, can reduce greatly and make and use cost; Because of the delayed startup device of prior art is housed on a certain compressor start circuit, two compressors are started respectively again, reduced starting current, electric load and the high request of electrical equipment electric wire; In addition, when adopting the shared off-premises station of many indoor sets,, can significantly improve radiating efficiency and avoid the phenomenon of outdoor " overworking " radiator because that off-premises station also is good heat dissipation effect, the size of air-cooled radiator is little.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is that the master that the utility model first embodiment band is analysed and observe looks schematic diagram.

Fig. 2 is that schematic diagram is looked on the left side that the utility model first embodiment band is analysed and observe.

Fig. 3 is the principle schematic of the utility model first embodiment.

Fig. 4 is the principle schematic of the utility model second embodiment.

Among the figure: indoor set 1, off-premises station 2, compressor 3, condenser 4, capillary 5, evaporimeter 6, pipeline 7, water inlet pipe 8, outlet pipe 9, delayed startup device 10, water pump 11, fan 12.

The specific embodiment

From Fig. 1 to Fig. 3, can see, water-cooled residential central air-of the present utility model, comprise indoor set 1 and off-premises station 2, two cover refrigeration systems are arranged in indoor set 1 shell body, refrigeration system comprises compressor 3, condenser 4, capillary 5, evaporimeter 6 is also continuous with pipeline 7 circulations, at a certain compressor start circuit delayed startup device 10 is arranged; In fact off-premises station 2 is exactly air-cooled radiator, and it has inlet tube and outlet tube 8,9 to link to each other with two condensers 4, has water pump 11 hot water in the condenser 4 to be extracted out and fan 12 blowing heat radiations.

Condenser 4 is the sleeve water cold type, and two tubule roads 7 of two cover refrigeration systems pass the big sleeve pipe of the plate-like that is filled with water, and the two ends of the big sleeve pipe of plate-like link to each other with the inlet tube and outlet tube 8,9 of air-cooled radiator respectively; The evaporimeter 6 of every cover refrigeration system is two coil pipes independently separately, V-shaped installation, the installation and two V-arrangement coil pipe pieces overlap.

When opening air conditioner, slightly postpone some startups than another air conditioner that is unkitted the delayed startup device start-up time that the compressor of delayed startup device 10 is housed, and so can reduce starting current; And the cost of two light duty compressors more than the one-tenth of a big compressor is original must be low; Also have the concentrated radiating effect of air-cooled radiator also can significantly improve.

The utility model second embodiment of Fig. 4 is with three shared off-premises stations of indoor set.More can avoid the phenomenon of outdoor " overworking " radiator.
