Description
Technical field
The utility model relates to a kind of central air conditioning plant, particularly relates to a kind of central air conditioning plant that can intermittently blow.
Background technology
Existing central air conditioning plant can be divided into air-supply output and two kinds of kenels of cold air output basically, wherein general cold air output all be for strong, in, syllogic such as weak adjusts wind speed, in order to reduce indoor temperature, though it can provide personnel to enjoy refrigerant impression in hot summer, yet because indoor cold air more or less can be indoor via the outflow of slits such as crack between a door and its frame, and outdoor hot-air also can be gone into indoor by described slit flow, so, cause the loss of cold air; Because of the design that has aircondition now is to adopt the output of syllogic cold air, the cold air output quantity of this syllogic is all greater than the cold airflow vector, therefore, make the running that air supply motor in the aircondition and frozen water valve do not stop, to reach the effect that reduces room temperature, when room temperature is reduced to the temperature value that aircondition sets, close the frozen water valve this moment, make frozen water no longer circulate in the frozen water pipeline, and air supply motor still keep ventilation state, after a period of time, when room temperature raises and surpass the temperature value that aircondition sets, the frozen water valve just begins to start running again, cooperates the air-supply action of air supply motor, makes aircondition be the cold air output state.
After the frozen water valve cut out a period of time, room temperature raise and surpasses set temperature value, and this moment is indoor will be sultry gradually, therefore, treat that the frozen water valve restarts, and after still need waiting for a period of time, indoor temperature just can have nice and cool impression, and personnel need stand the sultry of a period of time.In addition, the temperature control method of existing aircondition is to change and reach the temperature control effect with the wind speed that opening and closing of frozen water valve cooperates air supply motor, but because the water quality in the environment is generally not good at present.Cause use a period of time after, the frozen water valve produces corrosion or phenomenon of the failure such as stuck because of the impurity in the water easily, so not only loses the temperature control effect, the emptier puzzlement that increases maintenance.
Aforementioned existing when utilizing the frozen water valve to cooperate air supply motor to carry out temperature control for exempting, the frozen water valve is easy to generate corrosion or phenomenon of the failure such as stuck, therefore another kind of existing aircondition does not use the frozen water valve, make when room temperature reaches setting value, air supply motor is if still continue air-supply, then because the frozen water frozen water pipeline that still continued to flow, cause room temperature still can continue to descend, it is right if air supply motor is just out-of-blast when room temperature arrives setting value, then can not make indoor quick rise because of air does not flow again, and then produce sultryly, therefore need after a period of time, just to feel nice and cool that this kind do not use the existing aircondition of frozen water valve can not effectively reach the temperature control effect.
