Abstract
The utility model relates to a hot pump type one-pull-two air conditioner, and an outdoor machine which is composed of a set of compressor, etc. simultaneously drives two sets of indoor machines. A liquid storage tank is installed in front of the inlet of the compressor, high-temperature and high-pressure liquid outputted from the compressor is distributed by a four-way change valve firstly, and then the high-temperature and high-pressure liquid can regulate the operation of refrigeration and heating. Different working conditions of the two indoor machines are realized through controlling an electromagnetic valve, and five kinds of operating modes of refrigeration, heating, ventilation, automatic running and dehumidifying and automatic control functions of timing, constant temperature, wind direction, wind velocity, sleep, etc. are realized through micro computer technology.
Description
The utility model relates to the pump type heat one band two air conditioner that a kind of off-premises station with compositions such as compressors drives two indoor sets simultaneously.
In the prior art, off-premises station that family expenses one band diad formula air-conditioner is made up of two cover compressors, outdoor heat exchanger, capillary, ventilating system etc. and two indoor sets constitute.Realize the work of two indoor sets is controlled by the refrigerating and heating systems of two cover independent completions.This air-conditioner is actually single composition of tube of two cover one-to-one separated wall hanging type air conditioners.Its cost is higher.The off-premises station volume is big.Recently domestic also at a band diad formula air-conditioner of developing with two indoor sets of a cover refrigeration system band, but its function and operation mode are few.Can only separate refrigeration.
The purpose of this invention is to provide and a kind ofly drive the pump type heat separated wall hanging type air conditioner of two indoor sets simultaneously, when satisfying dual-use, reduce cost, and increase its heat-production functions with a cover refrigeration system.
The purpose of this utility model realizes by following technical measures: comprise an off-premises station, compressor is housed in the machine, outdoor heat exchanger, muffler, capillary, device for drying and filtering; Two indoor sets are equipped with indoor heat exchanger and aerofoil fan etc. in the machine.Technical characterictic of the present utility model is: be provided with surge drum before compressor; The connecting pipeline of off-premises station and indoor set is provided with four-way change-over valve and magnetic valve; Between outdoor heat exchanger and capillary, have additional one-way cock, be connected in the pipeline behind this one-way cock and another capillary paralleling.
The utility model drives two indoor sets with a cover refrigeration system, and adds parts such as four-way change-over valve, magnetic valve, capillary, check valve and surge drum in system, has increased heat-production functions.And indoor set start the back optimum Match of system pipeline and difficult problems such as control distribution of system refrigerant amount when different load have been solved.
Following the utility model provides embodiment in conjunction with the accompanying drawings.
Fig. 1 is a present embodiment refrigerating and heating systems schematic diagram.
As shown in Figure 1, compressor 8 sucks the low-pressure low-temperature refrigerant gas in the surge drum 4 and the compression work done.Listen high pressure, high temperature refrigerant gas by muffler 6 and four-way change-over valve 5 inlet chamber external heat exchangers 9 after compression.At this moment, high-pressure relay 7 is connected.High-temperature high-pressure refrigerant gas release heat in outdoor heat exchanger becomes the high pressure low temperature liquid refrigerant, the one-way cock 10 of flowing through then, device for drying and filtering 12 enters capillary 13 and carries out throttling, and the low pressure, low temperature liquid cold-producing medium after the throttling enters indoor heat exchanger 1 through magnetic valve 14, stop valve 15 and connection copper pipe 16.In indoor heat exchanger, the heat in the low pressure, low temperature liquid cold-producing medium absorption chamber and evaporate and become the low-pressure low-temperature refrigerant gas.The low-temperature refrigerant gas that comes out from indoor heat exchanger enters surge drum 4 through connecting copper pipe 2, stop valve 3 and four-way change-over valve 5.Finish a refrigeration work circulation thus.
In the time of need heating, four-way change-over valve switch operating position, from the high-temperature high-pressure refrigerant gas of compressor 8 output through muffler 6, four-way change-over valve 5 after stop valve 3 be connected copper copper pipe 2 and enter indoor heat exchanger 1.High-temperature high-pressure refrigerant gas release heat in indoor heat exchanger becomes the high pressure low temperature cold-producing medium.This gas carries out a throttling at capillary 13 places after flowing through and connecting copper pipe 16, stop valve 15, magnetic valve 14, carries out second throttle at capillary 11 places again after flowing through device for drying and filtering 12 then.Low temperature low pressure liquid refrigerants inlet chamber external heat exchanger 9 behind second throttle.In outdoor heat exchanger 9, the outer heat of low temperature low pressure liquid refrigerants absorption chamber flashes to low-temperature low-pressure refrigerant gas.This gas four-way change-over valve of flowing through enters surge drum 4, enters compressor once more, finishes once heating working cycles thus.
The utility model adopts electric automatic control elements such as micro computer, realization to components and parts open and close such as four-way change-over valve, magnetic valve, check valves, control such as commutate, close, close, to finish refrigeration, heat, to ventilate, five kinds of operation modes such as running automatically, dehumidifier and timing, constant temperature, wind direction, wind speed and sleep etc. are the control function automatically.
