Abstract
The invention relates to a multi-connection air conditioning unit and a working method thereof. When an air-side heat exchanger works but a water-side heat exchanger does not work, refrigeration agents can be controlled by a four-way valve to pass through the air-side heat exchanger to realize the refrigeration or heating of a machine unit; when the air-side heat exchanger does not work but the water-side heat exchanger works, the refrigeration agents can be controlled by a four-way valve to pass through the water-side heat exchanger to heat water, thereby recovering all heat; when compressors run at the same time, refrigeration oil separated out by an oil operator is respectively transmitted to oil inlet pipes through a distributor and then enters the compressors through an air suction pipe; when part of compressors run but part of compressors stop, since the air suction pipe is vertically arranged, the oil entering the compressors in the stopping state returns to the distribution device under the action of force of gravity and then enters the compressors in the running state, thereby ensuring the safe running of the compressors.

VRF Air Conditioning System of the present invention and method of work thereof, owing to be provided with the accessory that can realize multiple function, technology all is greatly improved on use, performance and function relatively now, can satisfy present client's user demand.
Description of drawings
In order to be easy to explanation, the present invention is done to describe in detail by following preferred embodiment and accompanying drawing.
Fig. 1 is the stereogram of VRF Air Conditioning System of the present invention;
Fig. 2 is the schematic diagram of VRF Air Conditioning System method of work of the present invention.
The specific embodiment
As depicted in figs. 1 and 2, a kind of VRF Air Conditioning System of the present invention, comprise chassis 1, and be arranged on The One On The Chassis constant speed compressor 2, digital compressor 3, oil eliminator 4, cross valve 5, water-side heat 6, air side heat exchanger 7, mistake cold loop 8, oil eliminator 9, control cabinet 10, distributor 14, oil inlet pipe 15, air intake duct 16, refrigeration system annex and connecting line; This control cabinet 10 comprises shell 11, and be arranged on dividing plate (not shown) in the shell 11, described dividing plate and shell 11 form lower floor's spatial accommodation and upper strata spatial accommodation, the electrical equipment that will be of little use is arranged on lower floor's spatial accommodation, electrical equipment commonly used is arranged on the upper strata spatial accommodation, can conserve space, and easy to use; The edge of described chassis 1 through hole is provided with the holding section 12 that holds lifting rope, and when lifting rope passed the through hole lifting, holding section 12 can hold lifting rope, and the phenomenon that can occur sliding does not lift steadily; Be coated with denoising device on the described compressor, described denoising device is made up of the sponge of arranging successively, stereotype, sponge and reclaimed rubber; The absorption frequency scope is big, can absorb together from the high frequency to the low frequency, can reduce noise, excellent noise reduction effect greatly.Set up one group of heat reclamation device in described water-side heat 6 cavitys, described heat reclamation device is provided with water inlet and delivery port, water can be heated, and it can provide thermobiosis hot water, can energy savings.Be provided with the entrance hole 13 that supply lines passes on the base plate of described control cabinet 10 and the side plate, electric wire can selectively pass through entrance hole 13, and the situation that wire rod can not occur wasting is installed also very convenient simultaneously.
This method of work is: when air side heat exchanger 7 work, when water-side heat 6 is not worked, can control cold-producing medium by air side heat exchanger 7 by cross valve 5, thereby the realization unit operation freezes or heats; When air side heat exchanger 7 is not worked, during water-side heat 6 work, can control cold-producing medium by water-side heat 6 by cross valve 5, water can be heated, thereby realize whole recuperations of heat, it can provide thermobiosis hot water, can energy savings; When compressor moved simultaneously, the refrigeration oil of oil eliminator 9 being separated by distributor 14 was transported to respectively in the oil inlet pipe 15, enters into compressor by air intake duct 16 again; When the part compressor operating, when another part compressor stops, because described air intake duct 16 vertically is provided with, the oil that enters into the halted state compressor is under the effect of gravity, get back to distributor 17, and then enter into the compressor of running status, guarantee the safe operation of compressor.
