Description

Air conditioning system with linked fire dampers

This creation is an air-conditioning system with linked fire dampers. In particular, it refers to an invention in which the fire dampers can be closed immediately and the air-conditioning system stops operating when a fire occurs.

According to domestic fire regulations, Article 49 of the standards for setting up fire safety equipment in various places states: "Operating rooms, delivery rooms, X-ray (radiation) rooms, intensive care units or anesthesia rooms and other similar places are exempt from the need to install sprinkler heads."

Special spaces such as operating rooms and intensive care units in medical institutions contain sophisticated medical equipment, as well as a large number of sick and injured patients who cannot move on their own. When a disaster occurs, disaster relief manpower must be relied upon to assist the injured and sick patients in evacuating before they can evacuate. The operation went smoothly. Therefore, in order to extend the waiting time for rescue, smoke and fire prevention measures should be strengthened in special spaces where sprinklers cannot be installed, and the disaster should be limited to certain areas to gain rescue and evacuation time for people in other spaces.

Most operating rooms and air conditioners in hospitals are configured with one central air conditioner supplying air conditioning to multiple operating rooms. When a fire breaks out in one of the operating rooms, the smoke caused by the fire will spread to other operating rooms through the pipelines. Although each operating room Operating rooms are all made of fireproof building materials, but it is unavoidable to prevent the intrusion of heavy smoke through pipes. Therefore, in order to improve the safety of the operating room, a single operating room is equipped with independent air conditioning equipment so that different operating rooms will not affect each other.

However, the operating room and the air-conditioning equipment still need to be connected by pipelines, so that the air-conditioning equipment can send the cold air into the operating room and then flow back to the air-conditioning equipment to complete the cycle. When a fire disaster occurs, thick smoke or high temperature may still escape into the operating room through the pipeline, causing the operating room to be damaged and unable to achieve the purpose of evacuation in place.

Therefore, in order to ensure the feasibility of evacuation in place, prolong the waiting time for rescue, and prevent thick smoke or high temperature from escaping into other spaces where there is no fire through pipelines, an air conditioning system with linked fire dampers is proposed to cooperate with an independent space. For use, the independent space is provided with an air inlet and a first return air outlet. The air conditioning system with linked fire dampers includes:

An air conditioning box body has an accommodating slot, an air outlet and a second return air outlet connected through the accommodating slot, and a fan is arranged in the accommodating slot; a first air duct has two opposite ends, The two ends are respectively connected to the air outlet and the air inlet; a second air duct has two opposite ends, the two ends are respectively connected to the first return air outlet and the second return air outlet; an air outlet fire damper is installed on the In the first air duct, the outlet fire damper has a first electric driver and a first damper body. The first electric driver is driven to selectively open the first damper body to unblock the first air duct, or to close it. The first damper body blocks the first air duct; a return air fire damper is disposed in the second air duct. The return air fire damper has a second electric driver and a second damper body to drive the second An electric driver can selectively open the second air door body to unblock the second air duct, or close the second air door body to block the second air duct; a smoke detector is provided in the second air duct , and between the return air fire damper and the second return air outlet, the smoke detector is electrically connected to the outlet fire damper, the return air fire damper and the fan; after the fan receives the thick smoke signal, the fan Stop the operation, and the outlet fire damper and the return air fire damper are immediately closed to block the first air duct and the second air duct respectively, thereby isolating the independent space.

Furthermore, the air conditioning box body has a return air damper, which is disposed on the second return air outlet and can selectively open or close the second return air outlet.

Further, the air conditioning box body has an outside air inlet, which is connected to the air outlet through the accommodation slot, and an outside air damper is provided at the outside air inlet. The outside air damper can selectively open or close the outside air. Air inlet.

Further, a sterilizing lamp, an ice water valve, a hot water valve and a humidifier are sequentially provided in the accommodation tank from the second return air outlet to the air outlet.

Further, a fire-proof switch is provided in the first air duct and between the outlet fire-proof damper and the air outlet. The fire-proof switch is electrically connected to the outlet fire-proof damper, the return air fire-proof damper and the fan; The fire switch detects a high temperature and generates a high temperature signal. When the outlet fire damper, the return air fire damper and the fan receive the high temperature signal, the fan stops running, and the outlet fire damper and the return air fan The fire damper is immediately closed to block the first air duct and the second air duct respectively, thereby isolating the independent space.

Furthermore, there is a fire signal receiving switchboard, which is electrically connected to the outlet fire damper, the return air fire damper and the fan.

According to the above technical characteristics, the following effects can be achieved:

1. When a fire breaks out in one of the operating rooms, the smoke detector detects thick smoke and generates a thick smoke signal. The fire damper installed in the pipeline will activate to close the pipeline when receiving the thick smoke signal, and the fan will receive the thick smoke signal. The thick smoke signal will stop operating immediately to prevent thick smoke or high temperature from escaping into other spaces where there is no fire through the pipes. This can prevent the disaster from occurring only in one of the operating rooms and prolong the safety of personnel in other spaces where there is no fire. Time to wait for rescue.

2. When a fire breaks out outside the operating room and the receiving switchboard receives an abnormal signal and sends out an alarm, at the same time, the fan will stop operating immediately after receiving the alarm from the receiving switchboard, and the fire damper will immediately stop operating after receiving the alarm from the receiving switchboard. Close, so that the operating room forms a closed space, isolated from the outside, and personnel can stay safely in the operating room, take shelter on the spot, and wait for rescue.
