Cooling system and waste water treatment


refrigerant compressor refrigeration

When talking about this system in the home builder รับสร้างบ้าน . Refrigerant compression is a cooling process that relies on the transformation of the refrigerant to a liquid state to recycle

  • Heat is released into air or water.
  • Expansion valve or liquid volume control valve It acts to reduce pressure and control the amount of liquid substance while the liquid flows into the evaporator.
  • Refrigerants are liquids with low evaporation points such as ammonia.
  • Heat from air or water. will be sucked into the evaporator panel or evaporative cooler panel
  • Evaporator is a component of the refrigeration unit to act to absorb heat with a refrigerant And when absorbing heat, the refrigerant changes state from liquid to gas.
  • Compressor or refrigerant gas compressor. It serves to reduce the volume and increase the pressure of the refrigerant.

Air conditioning cooling and heating heat pump type

This system heat pump house building company บริษัทรับสร้างบ้าน  It is considered a cooling and heating device work with electricity. In case of cooling the working cycle of the machine absorbs and transfers heat to the outside of the building in the case of heating the working cycle is reversed. It will draw heat from the outside of the building instead. This will reverse the working position between the condenser or evaporator or evaporator coil.

This heat pump air conditioner. It works well in moderate air conditions. Most of them have the same heat source and cold source for the interior of the building, but if you want to use it in a very cold climate Electrical heating equipment must be provided with an external coil to prevent freezing.

Absorption chiller

Absorption chiller It uses heat absorbers and heat sources instead of compressors for heat absorption and cooling.

  • Absorbents use a salt solution to extract steam from the evaporator It will cool the remaining water in the system.
  • The heat source controls the amount of excess evaporation from the salt solution.
  • Heat is absorbed by a cold-water heat exchanger.
  • The heat in the hot steam is absorbed and will condense into a water stop before being returned to the cooling coils.

Wastewater treatment system

Typically, external sewers transport wastewater from indoor water supplies to public sewers. before being used for water treatment by the state or central in the case of restrictions, cannot be sent to therapy. Having an internal wastewater treatment system is essential. The type and size of the wastewater treatment system depends on the number of water supplies and the permeability of the soil around the treatment pond. This will be known by testing the soil seepage. The system is designed by a sanitation engineer. The system must be approved by the relevant government agencies and reviewed before it is allowed to be used. However, building and environmental laws should be checked for regulations.

Pond is a pond built with waterproof material to seep through. To get wastewater out of the building and allow solid waste to precipitate and decompose. Then anaerobic bacteriostatic pretreatment clears the existing wastewater before it is sent out for final treatment.

Approximately 70% of the conditioned waste in liquid form flows to either system for final treatment.

  • The seepage field system is an open area with a longitudinal digging of absorbing grooves. to get wastewater from the septic tank to seep into the surrounding soil
  • The seepage system has internal walls with drainage holes to allow water to pass through easily. This system is commonly used when the soil has good permeability. and the groundwater level is at least 2′ (610) below the sump.
  • Permeability system in sand. It will consist of several branch pipes filled with gravel of the same size on top. The middle layer consists of coarse sand. And the bottom floor has a drain pipe perforated to allow the filtered water to flow out of this filter system. This system will only be used when the sump system is not suitable for use.
  • Effluent from wastewater treatment refers to wastewater that comes from water-consuming equipment. Such as sinks, bathtubs, showers, dishwashers. which these waters can treat and reused for use in toilet bowls for purification or for agricultural use. Today, few communities recycle wastewater. The use of the wastewater treatment system from reuse should be combined with other water-saving methods, such as the use of water-saving equipment. or storage of rainwater for use
  • Grease Trap (Precast Concrete)
  • Pond
  • Place septic tanks and seepages at least 100′ (30 m) away from artesian wells and at least 50′ (15 m) from natural waterways and at least 10′ (3 m) away from land boundaries. with the requirements of the relevant government agencies for data certainty for the latest large septic tanks used in each area)
  • For large septic tanks, the interior is divided into disinfection ponds. by using the siphon method Transfer through the drill pipe through the partition wall between the wells to each other. and will flow when the water loss reaches a certain level
  • Water distribution wells are equipped with devices to control the flow of waste water to the seepage pipes in the seepage field.
  • seepage field
  • Not longer than 60′ (18 m)
  • The trench should be perpendicular to the inclined plane.
  • The trench to place the seepage within the trench’s cross-section should be 18″ to 30″ (455 to 760) wide and 30″ (760) deep. and perforated pipes around to soil easily
  • At least 2′ 0″ (610) above groundwater level.
