Abstract
The invention relates to a split air conditioner consisting of an outdoor unit with a single compressor and a plurality of indoor units, which can respectively control and adjust the temperature of a plurality of rooms and has high energy efficiency ratio.
The refrigerating system is characterized in that a two-position three-way electromagnetic valve is arranged in the refrigerating system, n evaporators are provided with n-1 two-position three-way electromagnetic valves, and liquid refrigerants enter different evaporators to absorb heat and evaporate through reversing of the two-position three-way electromagnetic valves so as to respectively control and adjust the temperature of each room.
Description
The present invention is a kind of detachable air conditioner of being made up of the off-premises station and the Duo Tai indoor set of single compressor, and it can control and regulate the temperature in a plurality of rooms respectively.
Known to an off-premises station and two detachable air conditioners that indoor set is formed, its off-premises station needs be made up of two compressors.
Task of the present invention provides a kind of off-premises station and only needs a compressor and Duo Tai indoor set, can control and regulate a plurality of room temperatures and the high detachable air conditioner of Energy Efficiency Ratio respectively.
Following several technical schemes all can be finished task proposed by the invention.
Technical scheme one
Having only a compressor and having in the refrigeration system of n evaporimeter, between condenser and throttling arrangement, two-position three way magnetic valve is arranged, n evaporimeter is equipped with n-1 two-position three way magnetic valve, each evaporimeter has independent throttling arrangement to be connected with two-position three way magnetic valve, the indoor set that each room is made up of evaporimeter and blower fan etc.
Technical scheme two
Different is with technical scheme one, has only a throttling arrangement in the refrigeration system, places between condenser and the two-position three way magnetic valve.
Technical scheme three
Different is with technical scheme one, between throttling arrangement and two-position three way magnetic valve, evacuation valve is housed, a check valve is housed before or after each evaporimeter, has a pressure connection tube to be connected between each evacuation valve and the check valve with the pressure chamber of all the other evacuation valves.
Technical scheme four
Different is with technical scheme three, has only a throttling arrangement in the refrigeration system, places between condenser and the two-position three way magnetic valve.
Technical scheme five
Different is not have check valve in the refrigeration system with technical scheme three.
Fig. 1,2,3,4 is respectively the embodiment of technical solution of the present invention one, two, three, four, is a kind of refrigerating system figure of one drag two detachable air conditioner, and the present invention is further illustrated.
Shown in the figure:
11,21,31,41-compressor, 12,22,32,42-condenser, 13,23,33,43-two-position three way magnetic valve, 14A, 24A, 34A, 44A-A indoor machine evaporation, 14B, 24B, 34B, 44B-B indoor machine evaporation, 15A, 15B, 25,35A, 35B, 45-throttling arrangement, 36A, 36B, 46A, 46B-evacuation valve, 37A, 37B, 47A, 47B-check valve.
The electrical schematic diagram of Fig. 5 one drag two detachable air conditioner.
Shown in the figure:
The contact of WJ1, WJ1-1-A indoor set temperature controller, the contact of WJ2-B indoor set temperature controller, the actuating coil of KQ-two-position three way magnetic valve 13,23,33,43.
The refrigeration system course of work of one drag two detachable air conditioner shown in Figure 3 is, if determining the control sequence of two indoor sets is preferential control A indoor set, next is the B indoor set, work as A, when two residing room temperatures of indoor set of B all are higher than each indoor set setting, the contact of the temperature controller of each indoor set (WJ1) then, (WJ1-1), (WJ2) all be in closure, therefore compressor (31) energising work, higher pressure refrigerant gas is condensed into highly pressurised liquid through condenser (32) and enters two-position three way magnetic valve (33), because contact (WJ1-1) closure, the actuating coil (KQ) of two-position three way magnetic valve (33) has electric current to pass through, the passage in its left side is opened, the pathway closure on right side, highly pressurised liquid enters the top of evacuation valve (36A), when compressor (31) is taken out left cold-producing medium in B indoor machine evaporation (34B) to the greatest extent and is made its pressure be lower than the setting valve of evacuation valve (36A), evacuation valve (36A) is opened, high pressure liquid refrigerant enters evaporimeter (34A) heat absorption evaporation through throttling arrangement (35A) throttling becoming low pressure liquid becomes low-pressure gas, is back to compressor (31) by check valve (37A) and finishes circulation.When A indoor set room temperature of living in is reduced to setting, the contact of the temperature controller of A indoor set (WJ1), (WJ1-1) disconnect, because the residing room temperature of B indoor set still is higher than setting, so contact (WJ2) still is in closure, compressor (31) works on, because contact (WJ1-1) disconnects, the actuating coil (KQ) of two-position three way magnetic valve (33) does not have electric current to pass through, therefore its left channel is closed, right channel is opened, when compressor (31) is taken out left cold-producing medium in A indoor machine evaporation (34A) to the greatest extent and is made pressure be lower than the setting valve of evacuation valve (36B), evacuation valve (36B) is opened, liquid refrigerant enters evaporimeter (34B) heat absorption evaporation through throttling arrangement (35B), when the temperature in B indoor set room of living in is reduced to setting, the contact of the temperature controller of B indoor set (WJ2) disconnects, because contact (WJ1), (WJ2) all be in off-state, so compressor (31) quits work.
When if the B indoor set is in refrigerating state; when A indoor set room temperature of living in is gone up to the setting of A indoor set temperature controller; contact (WJ1); (WJ1-1) closure; two-position three way magnetic valve (33) is opened because of its actuating coil (KQ) energising makes left passage; right pathway closure; the A indoor set transfers refrigerating state to; the B indoor set transfers not refrigerating state to; when A indoor set room temperature of living in is reduced to setting; the A indoor set transfers not refrigerating state to; the B indoor set transfers refrigerating state to and continues cooling; thereby reach the purpose of controlling and regulating a plurality of room temperatures respectively, again since each room indoor set in working order in the transfer process compressor (31) do not need to shut down, so the on-off frequency of compressor is few; the start-stop loss is little, the Energy Efficiency Ratio height of air-conditioner.
