"Heat Salon" dehumidification heat pump unit structure diagram function detailed description

1. New return air mixed filter section:

The return air is mixed with the outdoor fresh air (the outdoor fresh air will continue to change due to climate changes, and the temperature and humidity of the fresh air will inevitably cause fluctuations in the indoor air temperature and humidity. This will not ensure that the indoor air temperature and humidity are at an ideal level. Within the control range), the mixed air enters the evaporator for air dehumidification after primary filtering.

2. Condensing section of dehumidifier:

1. The mixed moist air passes through the refrigeration evaporator, and circulates the refrigerant through the compressor. The evaporator absorbs heat in the air, the refrigerant changes from liquid to gas, and the surface temperature of the evaporator decreases, so that the moisture in the moist air is in the evaporator. When the surface reaches below the dew point temperature, a large amount of condensation is formed on the evaporator fins and becomes water, which flows into the drain pan along the fins and is discharged through the condensed water drain pipe.

2. In this dehumidification process, the temperature of the dry air after the dehumidification treatment will drop. When the indoor temperature is higher than the upper limit of the control value, the recovered air heat will pass through the pool water circulation heat exchanger (refrigeration system section water-cooled condenser) to the pool water. Auxiliary heating, while cooling the indoor air, when the indoor temperature is lower than the lower limit of the control value, the recovered air heat passes through the condenser in the dehumidification and condensation section to heat the indoor air to ensure that the indoor air temperature meets the requirements --- the condenser passes Refrigerant cycle The refrigerant changes from gas to liquid to release the heat of the air recovered by the evaporator. This heat is sent into the room through the air supply system to raise the temperature of the indoor air.

3. Exhaust section:

As the swimming pool air contains some bacteria, the operating cost of the equipment is considered, and the equipment load is fully reduced under the premise of meeting the temperature and humidity requirements. When the indoor dirty air enters the dehumidification heat pump through the return air duct, the first exhaust treatment is performed, and part of the dirty air is exhausted. The pipe is discharged outdoors.

4. The function of the hot and cold water coil:

1. In summer, if the user can provide chilled water from 7°C to 12°C, the user can adjust the temperature and humidity of the indoor air by using the chilled water cycle without starting the compressor according to the temperature and humidity value of the indoor air.

2. In winter, since the indoor air temperature is low when it is first used in winter, if the compressor is used for heating, the heating time is longer and the energy consumption is greater. For preheating, when the indoor temperature reaches the requirement, the compressor is started to make the dehumidification heat pump air-conditioning unit enter a fully automatic operation state. At this time, the indoor air temperature and humidity can meet the requirements by running the dehumidification heat pump air-conditioning unit. In this way, the air that reaches the indoor temperature and humidity control value after treatment is sent into the room through the air supply duct through the blower.

5. Refrigeration system section:

Including compressor, heat recovery auxiliary pool water auxiliary heat pump heating system, electrical control system, etc., this part and the front section are completely enclosed to prevent corrosion of electrical appliances and control systems caused by indoor air entry, and it is convenient for daily maintenance and maintenance.

All the above working processes adopt fully automatic control mode. The user only needs to set the indoor air temperature and humidity control value and the dehumidification heat pump air conditioning unit will enter the automatic operation state without special supervision.

The steel structure of all ventilation parts of the equipment is treated with epoxy resin for corrosion protection. The heat exchanger is treated with coating. The auxiliary heating system of swimming pool water circulation heat recovery uses high corrosion-resistant copper-titanium alloy pipes. The blower and exhaust fan use inner rotor pulleys. The motor is imported from ABB or Siemens, and the control system is controlled by a Siemens touch screen with a communication interface to facilitate firefighting linkage.
