Description

Accumulating type family expenses multiroom airconditioner

The utility model belongs to domestic air conditioner, particularly accumulating type family expenses multiroom airconditioner.

Existing domestic air conditioner has two kinds of patterns basically, i.e. single chamber air-conditioner (as window formula, split type) and multiroom airconditioner (dragging three formulas etc. as one drag two).The single chamber air-conditioner only is applicable to single room air conditioner, can't satisfy the instructions for use of many rooms, residential houses air-conditioning.Existing multiroom airconditioner is difficult to adapt to the air-conditioning needs of most of residential houses owing to shortcomings such as distribution capacity are big, cost an arm and a leg.Particularly owing to be subjected to the influence of outside air temperature, existing air-conditioner is in very big " imbalance between supply and demand " of the interim all existence of cold and heat supply.For overcoming this shortcoming, have to increase installed capacity, cause very big waste.

The purpose of this utility model provides that a kind of distribution capacity is little, moderate, each indoor set can use at the same time or separately flexibly, and can effectively overcome the accumulating type family expenses multiroom airconditioner of existing air-conditioner " imbalance between supply and demand ".

Accumulating type family expenses multiroom airconditioner of the present utility model is made up of an outdoor location and several indoor sets.Outdoor location is made of compressor, air heat exchanger, water-to-water heat exchanger, throttling arrangement, water pump and electric-control system etc.Indoor set is made of air heat exchanger, blower fan and electric-control system etc.Connect with pipeline between outdoor location and indoor set, in the pipeline by cold (heat) water.It is characterized in that: group has been gone into accumulator in the system of outdoor location.

Described accumulator is made up of airtight body and heat exchange pipe.Body is made of inner housing, heat-insulation layer and external protection.Heat exchange pipe places in the body, by cold-producing medium, fills Yi Shui between comb and body in the comb, and filled water amount is 85～92% of a body internal volume.

The body internal upper part is equipped with ripple or expander, in order to absorb the expansion amount of contraction that water becomes or the temperature difference causes.

Cold storage capacity is measured control by the liquid level difference measure and control instrument, and amount of stored heat is measured control by the measurement and control of temperature instrument.

Accumulating type family expenses multiroom airconditioner of the present utility model can make single-cooling type or air heat source heat pump type.

Accumulating type family expenses multiroom airconditioner of the present utility model is compared with existing domestic air conditioner, has the following advantages: this is a kind of multiroom airconditioner, can satisfy the instructions for use flexibly of air-conditioning at the same time or separately of a plurality of rooms, residential houses.Because group is gone into accumulator, make that distribution capacity reduces 40～50% under equal service condition, installed capacity reduces 50～60%, and cost reduces by 30～40%, and operating cost saves 20～30%.And the defrosting at heat pump heat supply is interim, no indoor " cold wind blows out " problem.The accumulator that group is gone into has played the effect as capacitor in the circuit, thereby has overcome existing air-conditioner effectively in cooling (heat supply) interim " imbalance between supply and demand ".

Below in conjunction with drawings and Examples, the utility model is further described.

Fig. 1 is the scheme of installation of accumulating type family expenses multiroom airconditioner.

Fig. 2 is the outdoor location structural representation of accumulating type family expenses multiroom airconditioner.

Fig. 3 is the accumulator structure schematic diagram in the outer device of accumulating type family expenses multiroom airconditioner.

Fig. 4 is the kind of refrigeration cycle schematic diagram of single-cooling type accumulating type family expenses multicell pocket outdoor location.

Fig. 5 is refrigeration (heat) the circulation theory figure of air heat source heat pump type accumulating type family expenses multiroom airconditioner outdoor location.

As shown in Figure 1 Domestic multi-room air conditioner by an outdoor location (11) with Several chamber devices (12) form, and use pipeline (13) to connect between the two. As shown in Figure 2 Outdoor location by compressor 1., air heat exchanger 2., water-to-water heat exchanger 3., throttling dress Put 4. 5., accumulator 6., 8. 7. water pump wait formation with electric-control system. As described in Figure 3 The body of accumulator is made up of inner casing (21), heat-insulation layer (22), external protection (23), Upper unit ripple in the middle and lower part device heat exchange pipe (24) in the body, body Formula expander (25), in heat exchange pipe by cold-producing medium, inner casing (21) with change Be filled with water between the hot type pipe, filled water amount is 85～92% of body internal volume.

Operation principle of the present utility model and using method are, such as Fig. 4, shown in Figure 5. Interim at cooling, outdoor location is routinely cooling operating mode operation generally; When not supplying Cold or, by electric-control system refrigeration is followed during much smaller than conventional cooling ability with cold Ring cutting is changed to the charging operation, utilizes refrigeration system ice making in accumulator, will The cold high density stores, and at this moment 6. accumulator is made evaporimeter and used cold-producing medium The order by compressor 1., air heat exchanger 2., throttling arrangement 4., accumulator 6. And finish a circulation.

When air conditioner load increases, install routinely cooling condition operation and can't satisfy usefulness During cold the requirement, switch to by electric-control system and to propose the operation of cold operating mode, make by the water heat exchange Device water part or all by accumulator 6. 3., ice-melt are extracted and are given store cold Amount makes to indoor supply water temperature and further reduces, thereby improves the confession of air-conditioner Cold energy power. Interim in the air heat source and thermal pump heat supply, outdoor location generally supplies routinely The thermal condition operation; When not needing heat supply or switch to accumulation of heat operating mode operation with thermal cycle, Utilize heat pump accumulator 6. in water heating, the heat high density is stored, this The time accumulator 6. make condenser and use, cold-producing medium in proper order by compressor 1., accumulation of energy Device 6., throttling arrangement 5., 2. air heat exchanger finish a circulation, work as air-conditioning Load increases, and install routinely heating condition operation and can't satisfy when using heat request, By electric-control system 8. special thermal cycle switch to accumulator heat source heat pump operating mode operation, Utilization is given the hot water that stores at accumulator in 6. and is made thermal source, improves the evaporation temperature of circulation Degree, thereby the heat capacity of raising air-conditioner, at this moment 8. accumulator makes as evaporimeter With, cold-producing medium in proper order by compressor 1., water-to-water heat exchanger 3., throttling arrangement 5., 6. accumulator finishes a circulation.

Interim in the defrosting of air heat source pump, 8. switch to accumulator by electric-control system Thermal source defrosting operating condition operation, cold-producing medium in proper order by compressor 1., air heat exchanger 2., throttling arrangement 5., 6. accumulator finish a circulation, at this moment accumulator is 6. Making evaporimeter uses. Because be to make the defrosting thermal source to give the hot water that stores in the accumulator, Thereby avoided indoor " cold wind blows out " phenomenon that defrosts interim.

When measuring much smaller than conventional cooling (heat) ability of air-conditioner with cold (heat), Air-conditioner can be by the work of " carrying while holding " method of operation.
