Preferably, the indoor unit 1 of the water-cooled central air conditioner comprises a fan, and CO released by the heating and pressure-reducing release device2Is driven by the fan and discharged out of the indoor unit 1.
In the traditional water-cooled central air conditioner, a chilled water supply pipeline enters an indoor unit 1 for heat exchange to take away heat in a greenhouse, and the heat returns to a host evaporator through a chilled water return pipeline; the invention arranges a branch (CO) on the chilled water supply pipeline2Release branch), when CO is required to be released into the greenhouse2While opening CO2Releasing the valve body on the branch to allow part of the chilled water to pass through the CO2The releasing branch flows to the main unit (evaporator) of the water-cooled central air conditioner, the heating and pressure-reducing releasing device is started, and CO is discharged2The hydrate releases CO after passing through a heating and pressure-reducing release device2Released CO2Driven by a fan of the indoor unit 1, the air flows downwards into the greenhouse. When the CO is not required to be released into the greenhouse2While turning off CO2Releasing the valve body on the branch to prevent the chilled water from passing through the CO2The release branch flows to the main machine (evaporator) of the water-cooled central air conditioner. Of course, heat and pressure reduction releaseThe discharge device also comprises CO2Control valve by controlling CO2Controlling the opening of the valve to control the indoor unit CO2The amount of (a) released.
