Definitions

  • the invention relates to dehumidification devices for reducing the moisture content in the air of indoor living spaces and keeping the same at the required level.
  • the invention particularly relates to a method developed for making more efficient use of the waste heat discharged from the condenser in the transition process within the dehumidification devices following removal of the air from the spaces to be dehumidified.
  • dehumidification devices carry out with dehumidification operation.
  • the essential point of dehumidification is to condense the water vapour found in the air and then convert it into water.
  • the dehumidification device extracts the water vapour found in the air together with the air and condenses this water vapour within the device.
  • the condensed water turns into water by the effect of the condensation.
  • the dehumidified air is then heated and then returned to the medium as dry air.
  • the dehumidifier is a machine that operates with a refrigeration cycle. It is based on the physics principle that the air in contact with a cooled surface leaves the water in it onto this surface that is cooler than itself. According to the operating principle of the device; the humid air retracted from the medium passes through cooled serpentines in the dehumidifier. These serpentines collect and condense a portion of the humidity that the air contains. The condensed water accumulates on the evaporator surface. The amount of water contained in the air passing through the evaporator has been reduced, but the temperature has also decreased. In this case, the relative humidity is still high. The temperature is increased by passing the air through the condenser. Thus, the air containing less water now reaches room temperature.
  • condenser heating is eliminated and replaced with a hot water heater instead, which causes additional energy consumption.
  • the pool site indoor temperature has to be heated to a higher value than the desired temperature value, since the condenser is again placed after the evaporator and the condenser capacity has to be higher than the evaporator capacity.
  • the dehumidifier device has a cooler connected thereto.
  • the cooler is designed to cool the dryer.
  • the regenerator has a heater connected up to here.
  • the heater is designed to heat the dryer so that the dryer is heated by the heater before entering the regenerator.
  • the application No. TR2015/08004, entitled “Industrial dehumidification system” relates to a dehumidification system comprising a vaporizer with a cooler.
  • the evaporator operates with the air having increasing temperature.
  • a compressor operates together with the evaporator and the second heat exchanger such that it would pressurize the cooler passing through the second heat exchanger.
  • the purpose of the invention is to make use of the condenser waste heat as desired and prevent the blowing temperature from rising excessively by sensitively controlling the temperature of the air blown into the indoor environment while using this waste heat.
  • Another purpose of the invention is to provide sensitive control of the blowing temperature by establishing a new system with the heat recovery exchanger and proportional by-pass damper mechanism in order to make use of the condenser waste heat capacity as needed by changing the position of the condenser within the dehumidifier device.
  • Another purpose of the invention is to prevent the blowing temperature from rising inadvertently by controlling the condenser waste heat indirectly and proportionally.
  • Another purpose of the invention is to prevent consumption of unnecessary energy while proportionally adjusting the temperature to be taken from the condenser.
  • Another purpose of the invention is to prevent the revision made on the process from negatively affecting the post-use maintenance costs and the total time period of use.
  • Figure 1 is a side view showing the air flow between the evaporator, condenser, and heat recovery exchanger components in the dehumidifier device.
  • Figure 2A is a perspective view of the moment when the bypass damper on the heat recovery exchanger of the dehumidifier device is active.
  • Figure 2B Is a perspective view of the moment when the bypass damper on the heat recovery exchanger of the dehumidifier device is passive.
  • the dehumidifier device consists of two separate air flow sections.
  • the heat recovery exchanger (4) is positioned so that the air coming from two separate air flow sections will pass through thereof. That is, while the evaporator (2) is found in the first air flow line, the condenser (3) is found in the second air flow line.
  • the most significant characteristic of the new design dehumidifier device is that the air coming from the evaporator (2) line does not come into contact with the air coming from the condenser (3) line at all.
  • a heat recovery exchanger (4) is found between the air flow sections.
  • Air inlet dampers (1) are provided on the air inlet sides of each air flow section, which are controlled by fresh air inlet and indoor air inlet ports and proportional damper motors.
  • the heat recovery exchanger (4) has two air inlet sections. From one of these, the air cooled by the evaporator (2) and dehumidified by condensing passes, while the air heated by the condenser (3) passes through the other air inlet section.
  • the air entering the heat recovery exchanger (4) from the evaporator (2) side is directly sent to the target medium from the medium outlet line (6) without encountering any obstacle, the air entering the heat recovery exchanger (4) from the condenser (3) line is discharged from the exhaust outlet line after passing through a bypass damper (5) formed of sections called as a bypass outlet channel (5.1) and a direct outlet channel (5.2) controlled by a proportional damper motor and having a winged structure that operates in opposite direction to each other.
  • bypass outlet channel (5.1) and the direct outlet channel (5.2) are of great importance. Heat is transferred from the air heated in the condenser (3) through the heat recovery exchanger (4), onto the air cooled in the evaporator (2) and dehumidified by condensing.
  • the temperature of the air cooled by the evaporator (2) and dehumidified by condensing is measured by a sensitive temperature gauge located at the exit of the heat recovery exchanger (4) and the proportional damper motor found at the other side of the heat recovery exchanger (4) and driving the by-pass damper (5), which adjusts the passage of the air heated in the condenser (3) through the heat recovery exchanger (4), in a precise manner with the temperature information obtained from this temperature gauge, and proportional opening and closing thereof can be ensured.
  • the bypass outlet channel (5.1) closes at a certain level and the direct outlet channel (5.2) opens.
  • the opening of the direct outlet duct (5.2) means that a larger part of the heated air in the condenser (3) is to be passed through the heat recovery exchanger (4).
  • bypass outlet channel (5.1) opens at a certain level and the direct outlet channel (5.2) closes.
  • the meaning of closing of the direct outlet channel (5.2) and opening of the bypass outlet channel (5.1) is that the air heated in the condenser (3) will have less heat transfer with the air leaving the evaporator (2).
  • the cooled and dehumidified air in the evaporator (2) is to be heated less and brought to the preferred temperature value.
  • the air cooled in the evaporator (2) and dehumidified by condensing is thus brought to the exactly desired and set temperature value, and blown to the medium through the medium outlet line (6).
  • the condenser (3) air that is heated in the condenser (3) and the needed amount of the waste heat of which is already transferred, is discharged to the external environment through the exhaust outlet line (7). In this way, the waste heat from the condenser (3) is fully utilized as needed and it is possible to precisely control the humidity and temperature of the air blown into the room.
