Strength of Industrial CO2 air energy heat pump water heater high temperature hot water
Heat pump water heater is a new type of hot water and heating heat
pump product, which is a heating equipment and hot water device
that can replace boilers. Compared to traditional solar energy,
heat pump water heaters not only absorb heat from the air, but also
absorb solar energy. The heat pump water heater absorbs heat
through the refrigerant temperature difference and compresses the
compressor to heat, and then exchanges heat with water, which
greatly improves the thermal efficiency and makes full use of new
energy. It is a new type of water heater that perfectly combines
the advantages of electric water heaters and solar water heaters.
At present, there are three series of heat pump water heaters: air
source heat pump water heater, water source heat pump and solar
energy type. It is one of the best equipment to develop and utilize
new energy. According to different heat sources, heat pumps can be
divided into air source heat pumps, water source heat pumps and
ground source heat pumps. The air source (solar) heat pump is one
of the most advanced products in the world today. The product uses
refrigerant as a medium. The refrigerant absorbs the energy in the
air (or sunlight) in the fan coil (or solar panel), and then passes
through the air. After the compressor compresses and heats, the
heat is transferred to the water through the heat exchange device
to produce hot water, and the hot water is sent to the user's
radiator through the water circulation system for heating or
directly used for hot water supply. Principle of heat pump hot
water unit:
The heat pump hot water unit follows the law of energy conservation
and the second law of thermodynamics. Using the principle of heat
pump, it only needs to consume a small part of mechanical work
(electric energy) to transfer the heat in a low temperature
environment (atmosphere or groundwater, etc.) to a high temperature
environment. In the water heater, it is heated to produce
high-temperature hot water. A heat pump can be compared with a
water pump. Water cannot spontaneously flow from a low place to a
high place. To transport water from a low place to a high place, a
pump must be used to consume a part of the electricity to heat the
water.
The CO2 air source heat pump heating technology has the
characteristics of strong adaptability to outdoor temperature in
cold areas, high outlet water temperature, and high heating
coefficient under the condition of large temperature difference
between supply and return water. Compared with the traditional
Freon working medium heat pump, the CO2 heat pump can reach a
temperature of more than 70 ℃, which can meet the needs of various
radiators and realize heating and domestic hot water supply. As a
refrigerant, carbon dioxide has the advantages of high density, low
viscosity, small flow loss, and good heat transfer effect.
Main Specifications. The nominal working condition (outdoor dry bulb temperature of 7°C) reaches the hot water inlet/outlet temperature of 50°C/70°C, and the COP is 2.46. Under low temperature conditions (outdoor dry bulb temperature -20°C), the hot water inlet/outlet temperature reaches 50°C/70°C, and the COP reaches 1.66.
energy saving effect. Compared with heating equipment such as oil-fired boilers, gas-fired boilers, and electric boilers, the energy-saving rate is more than 50%.
field of application. It is used in the construction industry, including public buildings and residential buildings such as civil buildings, office buildings, commercial buildings, science, education, culture and health, and residential buildings for centralized or distributed heating and domestic hot water.
