Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioning system that combines an energy-saving type outdoor air-conditioning air-conditioning unit using a dehumidifying heat pipe and a room air- and chilled beam units}

The present invention maximizes the dehumidification performance and significantly improves thermal efficiency and energy saving efficiency by precooling and reheating the outside air without additional energy consumption to the outside air introduced from outside the room. And an air conditioning system for combining the outdoor air-dedicated air conditioner and the chilled beam.

In addition, the present invention is characterized in that the supply air pressure (air flow rate adjustment) can be maintained constant by the variable airflow control system, and energy waste can be greatly reduced due to the air supply air supply cutoff control function.

In addition, the present invention provides an alternative embodiment for air conditioning in summer and winter, wherein cooling and heating coils are installed in place of the air-conditioner air conditioner cooling coils to enable cooling and heating according to the season, Can be minimized.

The quality evaluation of conventional air-conditioning equipment is based on the degree of comfort according to room temperature, humidity, air condition, indoor air quality, indoor noise level, and how economical due to initial investment, energy cost, maintenance maintenance cost, Flexibility of the system due to changes in room temperature or changes in indoor environmental conditions.

Recently, however, the quality evaluation of air conditioning facilities has been carried out in addition to the environmental certification evaluation items such as the ventilation technology and indoor environment creation technology required for the ecological environment, the energy saving performance of the system, and environmentally friendly factors.

As a countermeasure against this problem, air conditioning systems combining a chilled beam unit (a chilled beam unit or a radiating and heating panel and an external air-conditioning air conditioner) have been recently developed and distributed in Europe and the United States.

That is, the fundamental difference between the chilled beam air conditioning system and the conventional air conditioning system is that the chilled beam air conditioning system is a system for separating the cooling and heating and ventilation, and is similar to the radiating heating and cooling system in terms of supplying cold water and hot water, Convective heat exchange is carried out.

At this time, in the case of the chilled beam air conditioning system, the water transmitted through the piping is heat-exchanged with the room air passing through the "chilled beam" installed near the ceiling or the ceiling.

This chilled beam air conditioning system is designed to satisfy both comfort and energy saving of living space by using radiation and convection cooling effect. It was developed to increase cooling effect of ceiling radiation panel system.

In other words, this chilled beam system is a new concept air conditioning system that can minimize draft by turbulent air movement. It can be easily installed on the ceiling of existing building with low installation height, and compared with general duct system, Is a system that has the advantages of high heat exchange efficiency, low noise, and reduced piping installation area.

These chilled beam air conditioning systems can reduce the transportation power for air conditioning and have many advantages in terms of construction and indoor environment. Thus, spreading is spreading rapidly in Europe, and the domestic climate environment and air conditioning system Development of products suitable for the operating conditions is under way.

Specifically, the chilled beam air conditioning system, which is rapidly spreading mainly in Europe, is a system capable of mass production by concentrating the existing ceiling systems, which can reduce the floor height and reduce construction and management costs.

Compared with the conventional air-conditioning system, the chilled-beam air-conditioning system adopts the water-air conditioning system, which reduces the circulating air volume by 75 to 85% compared with the conventional system. It can be reduced by around 20%.

In addition, since the chill beam system provides a pleasant air conditioning environment and a beautiful ceiling, it is advantageous in various aspects such as shortening of bed height, reduction of conveying power, economical efficiency of construction and maintenance, Technology development for the introduction of the technology should be actively carried out.

However, in such a conventional chiller-beam air conditioning system, it is very important to design the attracting structure and attraction performance of the chill beam, which is a unit installed in the room. However, technological securing of attracting performance of the chill beam attracting structure is insufficient It is true.

On the other hand, the following table shows the air conditioners for outdoor air-conditioning for dehumidification that are combined with chilled beam units or radiating and heating panels which are being developed and developed until now.

2) Then, connect the outside air inlet duct and the outside air supply duct, that is, the primary air (PA), to the outside air dedicated air conditioner.

3) At this time, the air supply duct (primary air duct) specification is selected according to the low speed (or medium speed) duct design standard.

4) Afterwards, the outside air supply duct is connected to the primary air duct connection of the chilled beam unit installed in each room to be air conditioned from the outside air induction type air conditioner.

5) At this time, the outside air (primary air) is supplied by the blower installed in the air conditioner of the outside air type, and the supply air amount is supplied by the variable air amount control method so that only the optimum air amount can be supplied according to the actual use conditions.

At this time, the air volume control of the blower is performed by installing a static pressure sensor at 2/3 of the total length of the primary air supply duct and adjusting the rotation speed of the air supply fan (FAN) by the inverter (VVVF) so that a constant pressure is always maintained.

The attracted secondary air is chilled beam unit (Or chilled) or heated while passing through a cooling coil or a cooling / heating coils installed in the cooling / heating coil.

7) At this time, the exhaust duct should be installed separately.

≪ Example 2 >

Hereinafter, an embodiment of the air conditioning piping system among the air conditioning systems combining the above-mentioned Chill-beam unit and the air-conditioner dedicated air conditioner will be described in detail.

1) First, cold water or cold / hot water is supplied to the cooling coil or the cooling / heating coils in the outside air induction type air conditioner from the cold / heat source device so as to constitute the air conditioning piping system for circulation.

≪ Example 3 >

Hereinafter, an embodiment of the automatic control system among the air conditioning systems that combine the above-described chilled beam unit and the outside air dedicated air conditioner will be described in detail.

1) Control of supply fan (SF) and outside damper (MD-1)

When the air supply fan (SF) is activated in the central monitoring unit (BAS), the air conditioner starts to open with the air conditioner damper (MD-1) opened and the air conditioner (SF) Closed, the air conditioning is ended.

2) Air flow fan (SF) control

Install a static pressure detector (SD) at 2/3 of the total length of the primary air supply duct and control the inverter (VVVF) for controlling the number of revolutions of the supply fan (SF) motor so that the static pressure detection value is maintained at the set value. Proportional control (variable air amount control).

3) Control of outside air cooling amount (dehumidification amount) in summer (= constant control of outside air supply temperature)

First, the cold water flow rate control valve (CCV) proportionally controls the flow rate of the cold water so that the detection value of the temperature sensor (T1) installed on the rear surface of the cooling coil (cc)

At this time, the set value of the temperature sensor T1 is changed depending on whether the chilled beam of the heat-cooling type and the chilled beam unit of the sensible heat cooling type are installed. This is because the chilled beam unit Or may be generated depending on whether or not it is generated.

4) Summer heat pipe capacity control (eg cooling / recirculation) control

Examples of summer heatpipes Cooling and reheating are dependent on outside temperature conditions.

That is, as the outside air temperature increases, the temperature of the air passing through the heat pipe evaporator (pre-cooling coil) becomes lower, so that the cooling capacity of the cooling coil cc can be reduced to save energy for cooling, The reheating coil), the temperature of the air passing through the reheat coil is increased, so that the energy required for reheating can be reduced. When the reheated primary air over the room air dew point temperature is supplied to the chilled beam unit installed in each room, Can be prevented.

On the other hand, as the outside temperature is lowered, the opposite phenomenon occurs, and when the outside temperature is lowered to be lower than the room temperature, the necessity of the heat pipe is completely eliminated.

Therefore, it is sometimes necessary to limit the reheat amount and the preheating amount in the heat pipe in consideration of the outside air temperature and humidity condition and the cooling and dehumidifying ability of the installed cooling coil (cc).

At this time, the temperature of the air passing through the reheater is sensed and the reheat amount is regulated by opening and closing the automatic solenoid valve SV-1 installed in the refrigerant pipe circulating the heat pipe evaporator and the condenser step by step.

Also, since the outside air temperature is not as high as in the rainy season, it is impossible to preheat and reheat the outside air by using a heat pipe in a season where the outdoor humidity is high. Therefore, after cooling and dehumidifying in the dehumidifying coil 110, (RHV) is proportionally controlled so that the temperature of the temperature sensor (T3) installed in the supply duct is always kept constant.

5) Heating control of outside air in winter (= outside air supply temperature constant control)

The hot water flow control valve (HCV) is configured to proportionally control the hot water flow rate so that the detection value of the temperature sensor (T1) installed on the rear surface of the heating coil (hc) is always maintained at the set value.

6) Controlling the amount of steam in winter

Depending on the humidity of the humidity sensor (H) installed in the room, the humidification flow rate control valve (SV-2) installed in the supply pipe for humidification is turned on / off to maintain the humidity in the room.

7) Air-conditioning prevention control for dedicated outdoor air in winter

When the detection temperature of the temperature sensor T4 installed in the mixing chamber is lowered to a certain temperature or less when the air supply fan stops, the electric heater EH is turned ON / OFF to prevent the coil from being frozen.

8) Prevention of overheating / undercooling control can be achieved by adjusting the temperature of the hot water flow (T3) installed in the primary air supply duct and the temperature sensor (T1) installed at the back of the cooling coil (cc) The valve (HCV) is closed with the cold water flow control valve (VVV) to prevent overheating / subcooling.

9) Central supervisory control system (optional)

(VVVF) abnormality alarm, monitoring electric heater start / stop control and operation state, monitoring supply air temperature, and monitoring indoor humidity.

The present invention is summarized as follows.

2. The number of solenoid valves should be selected according to the capacity control range setting (for example, one coil for each hot water (room), one for each as needed)

3. The solenoid valve should be always open (nominally open type) and close when the outside air is not dehumidified (winter) (solenoid valve is electric DC12 volts or DC 24 volts ON / OFF type)

4. The auxiliary reheating unit (coil) is used for reheating when the outside air is cold and humid like the rainy season.

5. The type of air conditioner includes "vertical type" and "multi type" according to the arrangement type of each device in addition to "horizontal type" as shown in the above figure.
