In general, the variable air volume type HVAC system (hereinafter referred to as VAV system) can reduce the facility capacity by selecting the capacity of equipment considering the simultaneous load ratio.

In addition, the VAV system can save the energy because the air volume can be adjusted according to the load variation by installing the variable air volume unit for each room or zone.

Therefore, the VAV system is easy to cope with load fluctuations, has high responsiveness to load fluctuations, has good habitability, is relatively easy to perform air balancing, has flexibility in partitioning, and is easy to control individually.

However, the VAV system has a problem that the initial investment cost is large, and the operation and maintenance are difficult because the automatic control is complicated.

In particular, in order to perform all the functions required for the internal wiring of the indoor unit without using the power unit, such as transformer, heater control, thermostat control, communication module, etc., There is a problem that the operation time due to the internal wiring is very long when the work is performed.

On the other hand, due to the characteristics of ships or floating offshore structures (hereinafter referred to as "ships"), the ship's main power supply is basically 220V.

However, there is a serious problem of power and energy consumption in applying such main power to the VAV system as it is.

It can be understood that the present invention includes the driving unit 100, the heater 200, and the power unit 300 as shown in FIG.

The drive unit 100 controls the flow rates of the air supplied to the plurality of chambers 401, 402, 403, ..., N provided on the ship.

The heater 200 is electrically connected to the driving unit 100 and an auxiliary controller 450 provided in each of the plurality of the rooms 401, 402, 403, ..., ..., N) in accordance with the heating mode requested through the auxiliary controller 450 from any of the rooms.

The power unit 300 is electrically connected to the main power supply 500 of the ship, the drive unit 100 and the heater 200 and is connected to the main power supply 500 of the ship as an auxiliary power supply for operating the drive unit 100 And transmits a signal indicating whether or not the heater 200 is operated according to the heating mode to the heater 200.

Here, the driving unit 100 and the heater 200 are operated by the auxiliary power source switched by the power unit 300.

The present invention can be applied to the embodiment described above, and it goes without saying that the following embodiments are also applicable.

The driving voltage of the main power source 500 is higher than the driving voltage of the auxiliary power source and the driving voltage of the main power source 500 is generally about 220 V. However, ), But requires a separate operating voltage of about 24V.

Therefore, the power unit 300 is required.

On the other hand, the driving unit 100 reads the air flow rate sensor 130 mounted on the air conditioning pipes 601, 602, 603, ..., M facing the plurality of rooms 401, 402, 403, A flow pressure variable portion for varying the pressure of air supplied to the plurality of rooms 401, 402, 403, ..., N from the flow rate and pressure information of air in the air conditioning pipes 601, 602, 603, (110).

The driving unit 100 is electrically connected to the heater 200 and the power unit 300 and is heated by the heater 200 operated according to the heating mode to generate a plurality of indoor units 401, 402, 403, ..., N The overheating detecting unit 120 detects whether the air supplied to the heater 200 is overheated and transmits a signal for varying the heating temperature of the heater 200.

On the other hand, the flow rate pressure variable portion 110 is a damper that is mounted on the air conditioning pipes 601, 602, 603, ..., M to vary the degree of opening of the flow path toward the plurality of chambers 401, 402, 403, And an opening / closing actuator 112 for varying the degree of opening of the damper 111. As shown in Fig.

The overheating detection unit 120 reads the temperature sensor 140 mounted on the air conditioning pipes 601, 602, 603, ..., M facing the plurality of rooms 401, 402, 403, And a comparison analyzer 121 for comparing the temperature information of air in the air conditioning pipes 601, 602, 603, ..., M with the temperature range of the heating mode predetermined in the driving unit 100 in real time.

The overheat detecting unit 120 is electrically connected to the comparison analyzer 121 and the heater 200 so that when the comparison value of the comparison analyzer 121 is abnormal, And a heater control switch 122 for transmitting a signal for stopping the operation for a predetermined time to the power unit 300.

Therefore, when the driving unit 100 determines that the heating mode is requested by the auxiliary controller 450 and the heater 200 is to be turned on, the driving unit 100 outputs a digital signal to the power unit 300 to be described later, 300 can supply hot air to each of the indoor units 401, 402, 403, ..., N by supplying auxiliary power to the heater 200 while switching the relay (not shown).

The supply of the warm air to each of the rooms 401, 402, 403, ..., N by operating the heater 200 can be performed at a desired temperature of each of the residents of the rooms 401, 402, 403, ..., Is different.

In other words, hot air is supplied from the main air conditioner (not shown in the following), but when the hot air is supplied through the air conditioning pipes 601, 602, 603, Since the temperature loss is great until the warm air reaches, the heater 200 is operated to supply the warm air of the desired temperature to the residents of the respective rooms 401, 402, 403, ..., N within the correct temperature range to provide a pleasant indoor environment To help.

At this time, in order to precisely control the temperature of each of the indoor units 401, 402, 403, ..., N, the heater 200 frequently turns on and off using a relay (not shown) 200), the noise generated during the operation of the relay and its durability, that is, the service life can be considered as an important consideration.

Therefore, it is preferable to use a solid state relay (SSR) rather than a general mechanical relay.

This is because mechanical relays generate noises during switching operation and have a short life span. On the other hand, SSR is electronic, and therefore, it has no noise and has a long life.
