Description
Technical field
The present invention relates to air-conditioning and manufacture field, particularly relate to a kind of valve cap device realizing changes in temperature multi-gang air-conditioner simultaneously.
Background technology
Multi-connected air conditioner (heat pump) unit is called for short multi-connected machine, the single cooling cycle system be made up of the direct-evaporation-type indoor set of or number typhoon cold off-premises station linking number platforms identical or different pattern, capacity, it can directly provide the air after process to one or several region.Multi-gang air-conditioner is compared with traditional air conditioner, there is significant advantage: use brand new ideas, integrate multiple new and high technologies such as dragging many technology, intelligent control technology, multiple health technology, power-saving technology and network control technology, meet the requirement of consumer to the aspect such as comfortableness, convenience, and invest less, occupy little space, consume energy low, indoor set alternative is comparatively large, and automatic controlling level is high.
In order to can realize multi-online air-conditioning system multiple stage in machine freeze simultaneously or heat, be typically employed in prior art between off-premises station and indoor set and increase valve cap device to realize the function of changes in temperature simultaneously.As Fig. 1, show a kind of multi-online air-conditioning system of the prior art, it comprises an outer machine 101, three valve caps and ten interior machines, three valve caps are respectively the first valve cap 201, second valve cap 202 and the 3rd valve cap 203, magnetic valve is provided with in each valve cap, refrigerator pipes 102 is all connected with between outer machine 101 and each valve cap, heat pipe 103 and common pipe 104, first valve cap 201 is connected with three interior machines (machine 301 in first, machine 303 in machine 302 and the 3rd in second), second valve cap 202 is connected with two interior machines (in the 4th in machine 304 and the 5th machine 305), 3rd valve cap 203 is connected with five interior machines (machine 306 in the 6th, machine 307 in 7th, machine 308 in 8th, machine 310 in machine 309 and the tenth in 9th), the operation principle of this multi-online air-conditioning system: the duty first determining valve cap according to the mode of operation of air-conditioning internal machine and outer machine, the state of valve cap has two kinds: halted state and operating condition, wherein operating condition is divided into again refrigerating state and heats state, then, outer machine controls the switch of valve cap internal electrical magnet valve according to the operational mode of interior machine, finally select refrigerator pipes according to the switch of magnetic valve or heat pipe, when magnetic valve disconnects, valve cap is selected to connect refrigerator pipes, and when the solenoid closes, valve cap selects connection to heat pipe.During work, when valve cap is in halted state, with the mode operation that machine in being connected with it operates at first, such as, in first, machine 301 leaves refrigeration at first, after then outer machine 101 receives the refrigeration mode of machine 301 in first, the magnetic valve controlling the first valve cap 201 inside is in off-state, and the current state recording the first valve cap 201 is refrigerating state, and the current state of the first valve cap 201 is sent connected all interior machines; When valve cap is in operating condition, the state consistency of the interior confidential and valve cap connected could run, otherwise be in wait state, after first valve cap 201 as escribed above transfers refrigerating state to, then in machine 302 and the 3rd, machine 303 can only leave refrigeration in connected second, heat if opened, can not run, be in wait state.But, the interior machine connecting different valve cap can run different states, such as, first valve cap 201 is refrigerating state, in first, refrigeration left by machine 301, in second, in machine 302 and the 3rd, machine 303 is shut down, first valve cap 201 internal electrical magnet valve disconnects, second valve cap 202 is stopped status, in 4th, in machine 304 and the 5th, machine 305 is shut down, second valve cap 202 internal electrical magnet valve disconnects, 3rd valve cap 203 is for heating state, in 6th, in machine 306 and the 8th, machine 308 heats, machine 307 in 7th, in 9th, in machine 309 and the tenth, machine 310 is shut down, the inner solenoid closure of 3rd valve cap 203.
Due to while changes in temperature multi-online air-conditioning systems in increase valve cap device, each valve cap can connect machine in multiple stage simultaneously, and outer machine needs the information according to being connected interior machine with valve cap control and record the state of this valve cap, more complicated than the communication of common multi-connected machine.Current way is by machine control program in three pipeline type changes, goes to realize the controlling functions of valve cap for magnetic valve by interior machine.This way has following defect: 1, electromagnetic valve mechanism is controlled by interior machine due to needs, and therefore the installation site of magnetic valve is restricted, necessarily requires near indoor set, so magnetic valve work this will cause noise problem; 2, interior machine needs to set group number, thus make outer machine know the information of interior machine and coupled valve cap accurately, be convenient to corresponding interior machine Controlling solenoid valve, internal machine carries out setting group number and will make troubles to installation and maintenance, also not easy-to-search after breaking down; 3, need machine control program in three pipeline types changes, make in three pipelines that in machine and common air-conditioning, machine can not be general.
