The purpose of this utility model provides a kind of saving energy, and residential central air-device stably turns round.
For achieving the above object, following technical scheme has newly been adopted in this practicality: a kind of residential central air-device comprises a cold-warm type air-conditioning device, a water circle device and a control device, described cold-warm type air-conditioning device is made up of a compressor, four way solenoid valve, air side heat exchanger, water-side heat, throttle mechanism and refrigeration pipe arrangement, described compressor, four way solenoid valve, air side heat exchanger, water-side heat and throttle mechanism connect by refrigeration pipe arrangement pipeline, and described air side heat exchanger also comprises a condensation fan; Described water circle device is formed by water pump, with the water pump water pipe connecting, and two delivery ports are arranged on the water pipe, can and connect a plurality of indoor sets on two water delivery ports on the described water pipe; Described water-side heat also is concatenated on the water pipe; Described control device is electrically connected with compressor, condensation fan, four way solenoid valve and water pump respectively; Described compression is a frequency-changeable compressor, and described throttle mechanism is an electric expansion valve, and described electric expansion valve also is electrically connected with control device.
The residential central air-device of said structure, owing to adopted frequency-changeable compressor and electric expansion valve, electric expansion valve also is electrically connected with control device.The rotating speed that control device can be regulated frequency-changeable compressor according to the inflow temperature and the pace of change of water-side heat and the flow of electric expansion valve, when the low timed unit of load of air-conditioner is regulated the transhipment of frequency-changeable compressor low speed, and make the swollen valve joint of electronics be transferred to less flow, thereby that has avoided normal open residential central air-device does not stop startup and shutdown, make the running of air-conditioner steady, the fluctuation of water temperature is little, and the extra energy consumption when having reduced compressor start, according to surveying and determination, under department's load condition, adopt residential central air-device energy energy efficient 29% of the present utility model.
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.
Fig. 1 is the structural representation of residential central air-device of the present utility model;
Fig. 2 is the control circuit schematic diagram of residential central air-device of the present utility model.
Shown in Figure 1, household air conditioning device of the present utility model comprises a cold-warm type air-conditioning device 1, one water circle device 11, and a control device 20.
Cold-warm type air-conditioning device 1 comprises compressor 2, four way solenoid valve 3, air side heat exchanger 4, electric expansion valve 8, water-side heat 5, some check valves 6 and refrigeration pipe arrangement 7, described compressor 2, four way solenoid valve 3, air side heat exchanger 4, water-side heat 5 and throttle mechanism 6 are connected by refrigeration pipe arrangement 7 pipelines.Described compressor 2 is frequency-changeable compressors, and some check valves 6 can cooperate refrigeration, heat the flow direction of different regulating working conditions freezing liquids, and present embodiment is an example with four check valves, also has been connected in series a device for drying and filtering 9 and a reservoir 10 on refrigeration pipe arrangement 7.Electric expansion valve 8 can save the flow of transferring the cold-producing medium in the empty system refrigeration pipe arrangement, reservoir 10 can cushion the loading difference of required cold-producing medium under refrigeration, the different operating conditions of heating mode, cold-producing medium in 9 pairs of refrigeration pipe arrangements of device for drying and filtering carries out drying and filtration, described water-side heat 5 can adopt plate type heat exchanger, double pipe heat exchanger and shell-and-tube heat exchanger etc., present embodiment is example with the plate type heat exchanger, described four way solenoid valve can change the flow direction of cold-producing medium by refrigeration, refrigeration mode according to the signal of control device.
The flow direction of the cold-producing medium of cold-warm type air-conditioning device 1 in the solid arrow direction indication process of refrigerastion of Fig. 1: the HTHP vaporizing system cryogen that compressor 2 is discharged is by refrigeration pipe arrangement 7, in air side heat exchanger 4, carry out heat exchange with outside air, release heat, make cold-producing medium convert liquid state to, liquefied refrigerant the refrigeration pipe arrangement in through check valve 6, fluid reservoir 10, dry filter 9, electric expansion valve 8 enters plate type heat exchanger 4 through another check valve 6 again, recirculated water with water circle device 11 in plate type heat exchanger 4 carries out heat exchange absorption heat, make circulating water cooling, at this moment the cold-producing medium in the plate type heat exchanger 4 changes gaseous state into because of the heat absorption evaporation, enters compressor 2 by refrigeration pipe arrangement 7 through four way solenoid valve 3 then.At said process, because the running of water pump 12, the recirculated water in the water circle device 11 is lowered the temperature because of release heat through plate type heat exchanger 5, and the recirculated water delivery port 14 after will lowering the temperature then is transported to each indoor set, reaches the purpose of regulating room air.
When the residential central air-device when heating, cold-warm type air-conditioning device 1 is because the commutation of control device 20 control four way solenoid valves 3, the dotted arrow direction that the cold-producing medium that compressor 2 is discharged is pressed Fig. 1 flows, at this moment air side heat exchanger 4 absorbs heat from surrounding air, and cold-producing medium release heat in plate type heat exchanger 5 is heated to recirculated water.
Shown in Figure 2, control device 20 is electrically connected with compressor 2, electric expansion valve 8, four way solenoid valve 3, condensation fan 21, water pump 12 and ancillary apparatus 16 respectively, and its control method adopts fuzzy control.
When air conditioner heat-production, cooling condition conversion, become the flow direction of the freezing liquid in the cold pipe arrangement 7 of the transformation of the way by control device 21 control four way solenoid valves 8.When refrigerating and heating type aircondition 1 is heating in the process, when heating capacity was lower than workload demand, control device 20 started auxiliary electro-heat devices 16, and recirculated water is heated.
When the residential central air-device when fractional load (shutting down or temperature Change) as the part indoor set, control device 20 is according to inflow temperature control frequency-changeable compressor 2 low-speed runnings of water circle device 20, electric expansion valve 3 reduce the to freeze flowing velocity of pipe arrangement 7 inner refrigerants reduces the rotating speed of condensation fan 21 and water pump 12 simultaneously.Along with the load variations of air-conditioner, but control device 20 continuitys are regulated the rotating speed of frequency-changeable compressor 2 and the refrigeration flow of electric expansion valve 8, make the air-conditioner smooth operation.
Although only the utility model is illustrated, can makes other remodeling and change not breaking away from by the scope of claim of the present utility model definition with respect to above preferred embodiment.
