Abstract
The invention discloses an operating method for improving energy efficiency ratio and performance coefficient of an air conditioner, which comprises the following steps: in a parallel system consisting of a compressor with adjustable output capability and a plurality of compressors with fixed output capability, when partial load output of the compressor with adjustable output capability and full load output of over one compressor with fixed output capability have the same capability, selecting the full load output of the compressor with fixed output capability to replace the partial load output of the compressor with adjustable output capability so that the whole air conditioner system acquires higher refrigerating energy efficiency ratio and heating performance coefficient on the premise of keeping other conditions unchangeable. The sum of the startup capabilities of the over one compressor with fixed output capability is as same as the partial load output of the compressor with adjustable output capability. The compressor with adjustable output capability is a digital compressor. The operating method has the characteristics of flexible operation, high energy efficiency ratio and performance coefficient, energy conservation, environmental protection and wide application range.
Description
Technical field
The present invention relates to a kind of method of operating that improves the air-conditioning Energy Efficiency Ratio and the coefficient of performance.
Background technology
The technical method of the existing raising air-conditioning Energy Efficiency Ratio and the coefficient of performance mainly passes through: 1). and increase copper pipe and number of fins, reduce mode such as heat exchanger fin gap and increase the heat exchanger heat exchange area, this method can make cost significantly rise, and also can cause the air-conditioning volume excessive; 2) change the higher medium of the coefficient of heat transfer, as the water consumption substitution air, this method need be acquired equipment such as water pump, increases equipment cleaning frequency and breakdown maintenance rate; 3). improve the heat transfer temperature difference between environment temperature and the refrigerant, because environment temperature is not subjected to artificial control, the refrigerant state also can bring influence to overall system in the heat exchanger and change, and therefore, the practical operation feasibility of this method is relatively poor.
Summary of the invention
Purpose of the present invention aims to provide a kind of flexible operation, Energy Efficiency Ratio and coefficient of performance height, energy-conserving and environment-protective, raising air-conditioning Energy Efficiency Ratio applied widely and the method for operating of the coefficient of performance, to overcome weak point of the prior art.
A kind of method of operating that improves the air-conditioning Energy Efficiency Ratio and the coefficient of performance by this purpose design, it is characterized in that in the parallel system that the compressor adjustable by fan-out capability and the fixing compressor of a plurality of fan-out capability are formed, when the full load fan-out capability of the compressor of fixing when the output of the sub-load of the adjustable compressor of fan-out capability and one of them above fan-out capability is identical, select the fixing compressor of this fan-out capability to export at full capacity and replace the output of fan-out capability adjustable compression machine sub-load, under the constant prerequisite of other condition, make whole air-conditioning system obtain higher refrigeration efficiency than and the heating performance coefficient.
The sub-load of the compressor that the summation that the fixing compressor of a described above fan-out capability is exported at full capacity and fan-out capability are adjustable is exported identical.
The compressor that described fan-out capability is adjustable is digital compressor.
The present invention is in the parallel system of multi-joint machine; usually export the fixing compressor of adjustable several fan-out capabilities of compressor parallel to form its cold-producing medium compression member by an ability; and the ability need different according to indoor set; the refrigerant circulation of control system; between shutdown and maximum exportable load, make corresponding adjustable ability output.In measuring the experiment of air conditioner refrigerating Energy Efficiency Ratio and heating performance coefficient, when the ability of exporting at full capacity when output of the adjustable compressor section of fan-out capability load and the compressor that one of them above fan-out capability is fixed is identical, select for use the full load output of the fixing compressor of fan-out capability to replace the sub-load of the adjustable compressor of fan-out capability to export, under the constant prerequisite of other condition, can make whole air-conditioning system realize higher refrigeration efficiency than and the heating performance coefficient.
The present invention utilizes compressor can reach higher efficient and these characteristics of Energy Efficiency Ratio when peak load is exported, both need not air-conditioning system is structurally done any change, just realize zero improvement cost, can improve the Energy Efficiency Ratio and the coefficient of performance of air-conditioning again, realize energy-conserving and environment-protective.
The present invention has flexible operation, Energy Efficiency Ratio and coefficient of performance height, energy-conserving and environment-protective, advantage of wide range of application.
The specific embodiment
Below in conjunction with embodiment the present invention is further described.
Be that example describes only below with testing air conditioner refrigeration efficiency ratio under the standard cooling condition.
The method of operating of this raising air-conditioning Energy Efficiency Ratio and the coefficient of performance, in measuring the experiment of air conditioner refrigerating Energy Efficiency Ratio and heating performance coefficient, in the parallel system of forming by adjustable compressor of fan-out capability and the fixing compressor of a plurality of fan-out capability, when the full load fan-out capability of the compressor of fixing when the output of the sub-load of the adjustable compressor of fan-out capability and one of them above fan-out capability is identical, select the fixing compressor of this fan-out capability to export at full capacity and replace the output of fan-out capability adjustable compression machine sub-load, under the constant prerequisite of other condition, make whole air-conditioning system obtain higher refrigeration efficiency than and the heating performance coefficient.
The method of operating of this raising air-conditioning Energy Efficiency Ratio and the coefficient of performance is as follows:
Step 1 under the standard cooling condition, is measured the refrigeration efficiency ratio of air-conditioning system when only driving the fixing compressor of a fan-out capability, notes complete machine capability and Energy Efficiency Ratio;
Step 2, under the constant prerequisite of other condition, close the fixing compressor of fan-out capability, regulate the adjustable compressor of fan-out capability, the output of digital compressor just, the complete machine capability when making the fixing compressor start of the described fan-out capability of complete machine capability and step 1 is suitable;
Step 3 remeasures the refrigeration efficiency ratio of air-conditioning system, sets when the sub-load output of digital compressor reaches the described output of step 2, switches to the compressor start that fan-out capability is fixed, and can make the higher refrigeration efficiency ratio of whole air-conditioning system realization.
The compressor output of above-mentioned use crystallized ability, the actual measurement complete machine capability is 16650W, and power is 4615W, and Energy Efficiency Ratio is 3.608W/W.
Above-mentioned digital compressor is adjusted to 80% output, and the actual measurement complete machine capability is 15330W, and power is 4814W, and Energy Efficiency Ratio is 3.226W/W.
When in the air-conditioning system as when having the fixing compressor of a plurality of fan-out capabilities, only need startup ability summation and sub-load to export wherein one or more identical constant speed compressors of compressor and get final product.
The present invention is except can carrying out under the standard cooling condition, and is all suitable for the type and the operating mode of the various energy stable operation in the air-conditioning refrigeration system.
