[0039] Existing air-conditioning equipment is usually only responsible for a single function, such as processing fresh air, processing the mixture of fresh air and return air, and processing exhaust air. During an epidemic and when there are requirements for the number of air colonies, high-efficiency filters or plasma modules, electric purification modules and other sterilization and disinfection modules are additionally installed in the HVAC system to ensure safety.

[0040] The present embodiment is a concealed fan coil unit for emergency combined equipment suitable for wards with bathrooms, which integrates multiple air outlets for fresh air, return air, air supply, and exhaust air. Different valves are opened and closed according to normal and emergency situations to control the conversion of air channels to meet the needs of different air treatments in normal and emergency situations, and the air is filtered and disinfected by adding a filter module and a disinfection module. The present embodiment can simultaneously meet the requirements of indoor air temperature and humidity, colony count, and ventilation frequency in normal or emergency situations, and has a compact structure and can be concealed in the ceiling of the ward without occupying additional machine room area. In addition, since the equipment has multiple interfaces and multiple functions at the same time, it is suitable for forming an independent HVAC system in a single ward to avoid cross infection between patients in multiple wards, and can also connect the corresponding interface air ducts in multiple wards to the main pipe for unified processing according to the actual requirements of the project. Multiple assembled modules of the equipment can be quickly integrated and installed to quickly respond to sudden major epidemics. In the early stage of hospital construction when there is no epidemic, the filtering and disinfection modules can be selectively installed according to the hospital plan, but the access position of this module is reserved in the equipment, which can achieve the effect of saving the initial investment of the project construction. Moreover, the equipment's fresh air inlet, return air inlet, supply air inlet, and exhaust air inlet are all located on the side of the equipment, and the air duct is pulled out horizontally without increasing the ceiling height.

[0041] Embodiment 1: Water system operation: The chilled water processed by the refrigeration unit enters the surface cooler 12 from the surface cooler water inlet 10, exchanges heat with the processed air in the surface cooler, and then flows back to the refrigeration unit from the surface cooler water outlet 9. The electric proportional integral regulating valve controls this water loop to achieve temperature control of the ward where the equipment is located and hydraulic balance of the water circuit. In addition, the condensed water generated on the surface of the surface cooler is collected by the water collection tray 13 and flows from the condensed water outlet 11 to the condensed water pipe for centralized treatment and discharge.

[0042] The specific instructions for the air system work are as follows: Embodiment 2: See also Figure 5 , clean fresh air plus exhaust (no return air) working mode: the fresh air inlet 16 and the exhaust valve 4 are opened, the air flows through the disinfection module, and finally the qualified air is sent to the ward by the air supply port 15. The exhaust air in the ward passes through the return air inlet 5 and the exhaust valve 4, and the toilet exhaust air can be filtered together with the air in the ward through the exhaust port 17 and then discharged to the outside by the exhaust fan 3.

[0043] Embodiment three: See also Figure 6, Normally, the fresh air plus return air (toilet exhaust) working mode: the fresh air outlet 16 and the return air valve 6 are open, the exhaust valve 4 is closed, both fans are open, and the filter is installed as an option. The outdoor fresh air is introduced into the equipment through the fresh air outlet 16, and the return air in the ward passes through the return air outlet 5 and the return air valve 6 to the mixed air section. The fresh air and return air are mixed and sent to the surface cooler for heat exchange through the supply fan, and then sent to the ward. The toilet exhaust in the ward can be discharged to the outside through the toilet exhaust outlet 17 and the exhaust fan 3. In normal mode, the air supply filter 7 module is installed as an option according to the hospital construction situation.

[0044] Embodiment 4: Mixed air working mode in emergency severe working conditions: In severe weather, due to the excessively high / low outdoor temperature, the fresh air mode can guarantee the safety of indoor air to the greatest extent, but it will cause the indoor temperature to seriously deviate from the thermal comfort environment of the human body. Especially in severe winter, the fresh air working mode causes the indoor temperature to be too low, which is not conducive to the improvement of the patient's condition. Since the air conditioning equipment of the embodiment can integrate multiple functions of the HVAC system, it can be installed in a single ward as an independent system, and does not share ventilation ducts with adjacent wards, so there is no risk of cross infection of patients in multiple wards. Therefore, under severe working conditions, the working mode can be carried out in the fresh air plus return air mode, which is as follows: the fresh air inlet 16 and the return air valve 6 are opened, the exhaust valve 4 is closed, the two fans are opened, and the high-efficiency filters are installed at the air supply and exhaust. The outdoor fresh air is introduced into the equipment through the fresh air inlet 16, and the return air in the ward passes through the return air inlet 5 and the return air valve 6 to the mixed air section. The fresh air and the return air are mixed and sent to the surface cooler for heat exchange through the air supply fan, and then sent to the ward. The toilet exhaust in the ward can be discharged to the outside through the toilet exhaust port 17 and the exhaust fan 3.

[0045] Embodiment five: See also Figure 7 , Energy-saving working mode in normal transition seasons: When there is no epidemic, the energy-saving working mode can be turned on in ordinary wards without excessive requirements for air quality and safety. That is, the fresh air inlet 16 and the exhaust valve 4 are closed, the return air valve 6 is opened, the 8 supply fans are turned on, the exhaust fan 3 can be selectively controlled to start and close, and the filter is installed optionally. The return air in the ward is introduced into the equipment through the return air inlet 5, passes through the return air valve 6, and is sent to the surface cooler 12 by the supply fan for return air heat exchange treatment, and then sent to the ward through the supply air inlet 15. The fresh air in the ward is obtained by opening doors and windows.

[0046] The fans in the equipment are all variable frequency fans, which can be adjusted according to the different requirements for ventilation times in normal and emergency wards, as well as the negative pressure control requirements for emergency wards. The air valves in the equipment can be electric air valves or manual air valves.
