Water heater for hotel

Hotel water heater (heat pump) is a machine consisting of 4 main devices (Compressor, Condenser, Heat exchanger between air and heat carrier, expansion valve) operating according to the principle of thermodynamics with the purpose of transporting heat from one environment to another to heat the water stored in the thermal insulation tank, saving electricity (Structure and operating principle are similar to air conditioners)

Structure of water heater for hotel

– Kahawa heat exchanger (heat exchange technology of conduit pipes with anti-flow, higher heat generation efficiency than conduit technology in the tank of other brands)

– Kahawa compressor uses the world's leading brand compressors such as (Copeland, Panasonic, Hitachi, advanced technology, achieving high durability and efficiency in the heat pump industry)

– Kahawa condenser has a thick density and is coated with anti-corrosion layer for salty and acidic environments, preventing rust

– Kahawa throttle valve uses a 4-way valve for efficiency, durability, safety and defrosting

Kahawa heat pump structure

• Heat pump heatpump is imported in its entirety with full import certificate
• Insulated tank body is made of pressure-resistant antibacterial enamel-coated steel (enamel coating ensures heat retention and antibacterial)
• 50mm thick polyurethane insulation layer in the middle
• Powder-coated steel shell (Safe for equipment and users)
• Hot water tank with built-in backup resistor that automatically turns on to disinfect the system when maintaining the heat exchanger or when the heat exchanger has a problem, hot water still runs
• Heat exchanger heat exchanger shell is made of safe powder-coated steel
• Heat exchanger is coated with anti-corrosion and anti-rust layer for salty or acidic environments
• Wilo-Germany brand circulation pump runs smoothly and durably
• Panasonic compressor Japan
• High heating coefficient, high COP, heats water quickly
• Production system on modern Japanese technology line ensures compliance with EU export standards
• Central water heater heat pump Heatpump Kahawa is a smart choice for everyone and every family. Outstanding Japanese exchange technology with sleeves and tubes brings high heat exchange efficiency and anti-turbulence compared to other brands.

How heat pump works (water heater for hotels)

Heat pump also known as "central water heater" is a machine that uses the thermodynamic principle of 4 cycles:

- Evaporation stage (the heat carrier absorbs the ambient air temperature and heats up to evaporate into a warm gaseous heat carrier, the air loses heat and condenses into water on the evaporator.

- Compressor heats up the heat carrier, the heat carrier increases rapidly when a compressor force is applied to it.

- Condensation stage (the heat carrier when leaving the compressor is heated up to 100 degrees Celsius, enters the condenser, where it transfers heat to the water to heat up to the required temperature of 55 to 65 degrees Celsius, and is led to the insulation tank to keep the heat

- Throttle valve (after the heat carrier transfers heat to the hot water, it continues to pass through the throttle valve to form a closed loop.

Therefore, the heat pump water heater is the optimal solution to save energy for the hot water needs of families or production facilities in the regions has a hot and humid climate, like Vietnam.

Central hot water system Using Kahawa heatpump technology is currently popular and widely used because of its superiority such as saving 70% of electricity compared to electric water heaters, high electrical safety, providing hot water with large demand, durable and stable.

With a central hot water system with a return line design - there is always hot water at the tap when needed without waiting time. Only 1 device is needed to provide hot water for the entire building.

Advantage

• Significant savings in equipment and fuel costs, minimizing total power sources, backup power sources/generators, helping owners of motels, hotels, swimming pools, resorts, etc. quickly recover capital
• Simple system installation and maintenance without causing changes or affecting the structure of the house.
• Absolute safety, fast heating, large supply flow
• High efficiency and energy saving
• High durability, intelligent automatic operation - · Low operating costs for the system
• Simple, common & economical repair and maintenance
