Above-mentioned refrigeration system is on existing Split type air conditioner basis, to have increased water heater 2 and air draft heat dump 4, simple in structure,Can make split typely, be divided into water heater 2, air draft heat dump 4, outdoor heat exchanger 5,10 4 parts of room air conditioner, pressContracting machine 1 equipment such as grade can focus on one with outdoor heat exchanger 5, and each several part connects with ready-packaged joint, with existing Split type air conditionerMounting means is similar.
This air-conditioning system mainly contains three kinds of operating conditions: send cold wind, send hot blast, water heating separately.
In the time sending cold wind summer, room air conditioner 10 send cold wind as evaporimeter to room, outdoor heat exchanger 5, air draft heat dump4 as condenser to outdoor heat radiation, refrigerant circulation process is: the 3 → air draft of compressor 1 → water heater 2 → four-way change-over valve inhaleHot device 4 → outdoor heat exchanger 5 → device for drying and filtering 7 → expansion throttling device 8 → device for drying and filtering 9 → room air conditioner 10 → four-wayReversal valve 3 → gas-liquid separator 12 → compressor 1. In this process, high temperature refrigerant in can heating water heater 2 fromWater, when in the non-culinary art moment, does not have oil smoke used heat, and mist extractor blower fan is only got rid of room waste gas, part or all air-conditioningCondensation heat can first be discharged to outdoor by air draft heat dump 4, remainder is discharged to outdoor again by outdoor heat exchanger 5, when in cookingPrepare food the moment, condensation heat can only be discharged to outdoor by outdoor heat exchanger 5.
In the time sending hot blast winter, room air conditioner 10 is converted into condenser and send hot blast to room, outdoor heat exchanger 5, air draft heat absorptionDevice 4 is converted into evaporimeter and absorbs heat from outdoor or oil smoke used heat, and four-way change-over valve 3 commutates, and refrigerant circulation process is: compressionMachine 1 → water heater 2 → four-way change-over valve 3 → room air conditioner 10 → device for drying and filtering 9 → expansion throttling device 8 → device for drying and filtering7 → outdoor heat exchanger, 5 → air draft heat dump, 4 → four-way change-over valve, 3 → gas-liquid separator, 12 → compressor 1. In this process,Water heater 2 is stopped using conventionally, and high temperature refrigerant send the needs of hot blast for meeting room air conditioner 10, if met simultaneouslyThe needs that water heater 2 heats, can only strengthen power system capacity, when in the non-culinary art moment, there is no oil smoke used heat, outdoor heat exchanger5 from outdoor air heat absorption, when in the culinary art moment, has oil smoke used heat, and air draft heat dump 4 absorbs heat from oil smoke, and blower fan 6 is notWork, or blower fan 6 turns round, and outdoor heat exchanger 5, air draft heat dump 4 are worked simultaneously, respectively from outdoor air, oil smokeHeat absorption.
When in transition season, the operating condition of air-conditioning system is similar with above-mentioned each operating mode.
In the time of independent water heating, air-conditioning system is in heating operation operating mode, the operating mode while sending hot blast with above-mentioned winter, but blower fan 11Do not work, do not send hot blast to room, the condensation heat of cold-producing medium is all for the running water of heating water heater 2.
In Fig. 2, outdoor heat exchanger 5, air draft heat dump 4 are connected in parallel in refrigeration system, by electric control valve 13,14 or electromagnetismBoth operations of valve control, in the time having used heat to utilize, air draft heat dump 4 is worked, otherwise does not work, both phase mutual interferenceLess, be conducive to the stable operation of system. System is provided with liquid-sighting glass 20, reservoir 22, unidirectional expansion throttling device 19, forThe check valve 15,16,17,18 of change working, the system that the capacity that is applicable to is larger.
