The working process of the cooling and heating cycle adjusting system for the terrace at the indoor ice and snow place provided by the embodiment of the application is explained below. The liquid inlet of the evaporator receives the liquid refrigerant supercooled by the subcooler 22 through the evaporator liquid supply pipe, and after the liquid refrigerant enters the evaporator, the secondary refrigerant in the evaporator, which flows back from the secondary refrigerant circulating liquid storage tank 30 through the secondary refrigerant return pipe, is refrigerated, and at the moment, the secondary refrigerant finishes refrigerating the refrigerating unit 36, and the temperature is higher; the refrigerated secondary refrigerant is conveyed into the secondary refrigerant circulating liquid storage tank 30 by the secondary refrigerant conveying pipe, after receiving the low-temperature secondary refrigerant refrigerated by the evaporator, the secondary refrigerant circulating liquid storage tank 30 conveys the low-temperature secondary refrigerant to the refrigerating unit 36 through a refrigerating output pipe, the refrigerating unit 36 is refrigerated, the temperature of the refrigerating unit 36 is reduced to a set value, then the secondary refrigerant with higher temperature after being refrigerated by the refrigerating unit 36 is conveyed into the secondary refrigerant circulating liquid storage tank 30 through a refrigerating return pipe by the refrigerating unit 36, and the secondary refrigerant with higher temperature is conveyed into the evaporator through the secondary refrigerant return pipe by the secondary refrigerant circulating liquid storage tank 30 for cooling, so that the refrigerating process in the whole working flow is completed.
When the liquid refrigerant subcooled by the subcooler 22 is used for refrigerating the secondary refrigerant, the liquid refrigerant absorbs heat for vaporization, the vaporized refrigerant is sucked into the compressor 2 through the compressor air suction pipe by the evaporator for compression, the high-temperature gaseous secondary refrigerant compressed by the compressor 2 is conveyed to the first condenser 5 through the compressor exhaust pipe by the compressor 2, and after the high-temperature gaseous secondary refrigerant enters the first condenser 5, on one hand, the heat carrier which is returned from the heat carrier circulation liquid storage tank 11 through the heat carrier return pipe in the first condenser 5 is heated, and at the moment, the heat carrier has already heated the heating unit 16 and is low in temperature; the heated heat-carrying agent is conveyed into a heat-carrying agent circulating liquid storage tank 11 by a heat-carrying agent conveying pipe, after receiving the high-temperature heat-carrying agent heated by the first condenser 5, the heat-carrying agent circulating liquid storage tank 11 conveys the high-temperature heat-carrying agent to a heating unit 16 through a heating output pipe, the heating unit is heated, the temperature of the heating unit 16 is increased but is set, then the heating agent with lower temperature after the heating unit is heated is conveyed into the heat-carrying agent circulating liquid storage tank 11 by the heating unit 16 through a heating return pipe, and the heat-carrying agent with lower temperature is conveyed into the first condenser 5 by the heat-carrying agent circulating liquid storage tank 11 through the heat-carrying agent return pipe to be heated, so that the heating process in the whole working flow is completed.
The gaseous high-temperature refrigerant compressed by the compressor 2 heats the heat-carrying agent, releases heat and liquefies, is transmitted to the second condenser 21 by the first condenser 5 through the first pipeline for sufficient condensation again, the liquid refrigerant after complete condensation is transmitted to the subcooler 22 by the second condenser 21 through the third pipeline for subcooling, and the subcooled liquid refrigerant is transmitted to the evaporator through the evaporator liquid supply pipe by the subcooler 22 for cooling the secondary refrigerant, so that the whole working process of the cold-heat circulation adjusting system for the indoor ice and snow terrace is completed.
After the corresponding refrigeration process and heating process are completed, the temperatures respectively reached by the refrigeration process and the heating process need to be controlled within a certain range, wherein the refrigeration temperature control process specifically comprises the following steps: when the temperature of the secondary refrigerant in the secondary refrigerant circulating liquid storage tank 30 is higher than the set highest temperature value, the cold exchange circulating pump 29 and the evaporator electromagnetic valve 24 are started, the evaporator inlet stop valve 27 and the evaporator outlet stop valve 12 are opened, the secondary refrigerant is cooled by utilizing the evaporation and heat absorption of the refrigerant supercooled by the subcooler 22 in the high-efficiency evaporator, so that the temperature value of the secondary refrigerant circulating liquid storage tank 30 is lower than the set highest temperature value, when the temperature of the secondary refrigerant in the secondary refrigerant circulating liquid storage tank 30 is detected to be lower than the set lowest temperature value, the evaporator electromagnetic valve is closed, the refrigerant does not pass through the evaporator, so that the temperature of the secondary refrigerant in the secondary refrigerant circulating liquid storage tank 30 is raised to be higher than the set lowest temperature value, when the surface temperature value of the ice and snow place is detected to be higher than or equal to the set highest temperature value, the secondary refrigerant enters the refrigeration U-shaped, thereby reducing the surface temperature of the terrace at the ice and snow place to be lower than the set maximum temperature value. When the surface temperature of the ice and snow place terrace is detected to be lower than or equal to the set lowest temperature value, the refrigerating U-shaped terrace cold pipe 34 does not receive secondary refrigerant any more, so that the temperature value of the ice and snow place terrace is raised to be higher than the set lowest temperature value.
The heating temperature control process comprises the following steps: when the temperature of the heat carrier in the heat carrier circulation liquid storage tank 11 is lower than the set lowest temperature value, the heat exchange tube inlet stop valve 6 is opened, the heat exchange circulation pump 19 is started, and the heat carrier is heated by the high-temperature gaseous refrigerant discharged by the compressor 2, so that the temperature value of the heat carrier is higher than the set lowest temperature value. When the temperature of the heat carrier in the heat carrier circulation liquid storage tank 11 is detected to be higher than the set maximum temperature value, the exhaust pipeline bypass valve 3 is opened, the first condenser inlet stop valve 4 is closed, and the high-temperature gaseous refrigerant discharged by the compressor 2 does not pass through the first condenser 5, so that the temperature value of the heat carrier in the first condenser 5 is reduced to be lower than the set maximum temperature value. When the temperature of the top floor surface layer of the building below the floor in the ice and snow place is detected to reach or be lower than the set lowest temperature value, the heat-carrying agent enters the heating U-shaped floor heat pipe 14, the heating U-shaped floor heat pipe 14 heats the top floor surface layer of the building below the floor in the ice and snow place, so that the temperature value is raised back to the set lowest temperature value, when the temperature of the top floor surface layer of the building below the floor in the ice and snow place is detected to reach or be higher than the set highest temperature value, the heating U-shaped floor heat pipe 14 does not receive the heat-carrying agent any more, and the temperature value of the top floor surface layer of the building below the floor in the ice and snow place is lowered to the set highest.
