Abstract


In this paper, the conventional heat pump air conditioner penetration and usage is not high , and the hot water needs of the growing status of the spirit of energy innovation proposed a standalone mode , that is, a separate system of hot water , a separate heating , separate cooling and heating plus hot water supply and cooling system increases the hot water mode , you can run all year round multi-function heat pump air conditioner . Conducted a trial of the experimental prototype of multi-function heat pump air conditioners and related performance tests . The trial is ready to adopt the heat recovery system feasibility before the product prototype trial , the reliability of a test and evaluation , to achieve the selection part of improving heat recovery system and determining the parameters of the control system is running , and the final production the purpose of the market demand for the product . Through the test , to determine and improve the operating mode of the prototype and the corresponding control strategy , control parameters , and to test the reliability of the prototype , the feasibility and operational characteristics of the test study . The test results show that as long as the control strategy for rational design prototype , the recovery process of the heat of condensation of the heat pump air conditioner is feasible, and the operation of the experimental prototype is reliable . The prototype run effect is satisfactory . Both to meet the annual refrigeration, heating , air-conditioning , but also bear some or all of the domestic hot water supply load . At the same time , the prototype also has the advantages of low power consumption , refrigeration coefficient of performance COP . Various error in the testing process , this paper also elaborates the general process of trial error and data processing . Therefore , the new multi-function heat pump air conditioner design standalone mode is indeed an energy efficiency , and the practicality of results to meet the market demand . Due to the limitations of the test conditions and other factors , in addition to the kinds of difficulties encountered in experiment underestimated , leading to the trial of this article , there are some inadequacies , at the same time , the experimental prototype of a final product , but also need to further optimize the match between the various devices relationship . The purpose of this paper is to provide a reference for the research and development of the prototype of such products can provide the basis to solve the domestic heat pump air conditioner condensing heat recycling technology .
