The composition and operation process of air source heat pump triple supply system

The triple supply system includes the main engine part (water pump, expansion tank, etc.), indoor terminal part (including wire controller, etc.), indoor floor heating part (including water separator and thermostat, etc.), and central hot water part (water tank, return Water control, etc.).

The triple supply generally has five modes: "refrigeration", "cooling and hot water", "hot water", "heating", and "heating and hot water". When air conditioning and hot water are required, set the "cooling and hot water mode". In this mode, when the return water temperature of the air-conditioning pipe is higher than 12℃, it will start the "refrigeration" operation, until the return water temperature is lower than 7℃ (settable) and stop; when the water temperature in the hot water tank is lower than 50℃, it will start" "Hot water" runs until the water temperature reaches 55°C (can be set) and stops; when the return water temperature is higher than 12°C and the water temperature in the hot water tank is lower than 50°C, start the "cooling and hot water" operation until the water temperature of the hot water tank When it reaches 55°C or the air-conditioning return water temperature is lower than 7°C (settable), it will shut down. In this mode, start the end of the air conditioner (fan coil) to get a cool and dry indoor environment that maintains the set temperature, and turn on the hot water faucet to get domestic hot water at 50-55°C.

In the case where air conditioning is required, set the "cooling mode". In this mode, when the return water temperature in the air-conditioning pipe is higher than 12°C, the "refrigeration" operation will be started, and it will stop until the return water temperature is lower than 7°C (settable); the hot water function will not start. In this mode, start the end of the air conditioner (fan coil) to get a cool and dry indoor environment that maintains the set temperature.

In the case where only hot water is required, set the "hot water mode". In this mode, when the water temperature in the hot water tank is lower than 50°C, the "hot water" operation will be started, and the machine will stop until the water temperature reaches 55°C (settable). In this mode, turn on the hot water faucet and you can get domestic hot water at 50-55°C.

In the case where only heating is required, set the "heating mode". In this mode, when the return water temperature in the air-conditioning pipe is lower than 40°C, the "heating" operation will be started, and it will stop until the return water temperature is higher than 45°C (settable); the hot water function will not start. In this mode, start the end of the air conditioner (fan coil) or start the floor heating thermostat to get a warm and comfortable indoor environment that maintains the set temperature. When heating and hot water are required, set the "heating and hot water mode". In this mode, when the temperature of the hot water tank is lower than 50℃, it will start the "heating water" operation, and stop until the water temperature of the hot water tank reaches 55℃; when the return water temperature of the air conditioning pipe or floor heating pipe is lower than 40℃, it will start "Heat" operation, until the return water temperature is higher than 45℃ (settable), stop; when both "heating" and "hot water" are needed at the same time, the hot water will be started first, and then switch to when the hot water reaches the set temperature Heating. In this mode, start the end of the air conditioner (fan coil) or start the floor heating thermostat to get a warm and comfortable indoor environment that maintains the set temperature; turn on the hot water faucet to get domestic hot water at 50-55°C.
