Description
CO2 air
to water heat pump is a sustainable technology.
Consumers
around the world are looking for sustainable, cost-effective alternatives to
traditional fossil fuel appliances to meet their hot water and space heating
needs.
Using
natural carbon dioxide as a refrigerant and achieving a high coefficient of performance
(COP), carbon dioxide heat pumps offer ecological and economic benefits.
The
Leomon CO2 heat pump is our state-of-the-art design and represents half a
century of expertise and experience we have accumulated in manufacturing water
heaters exclusively.
Using
proven technology and breakthrough design, CO2 heat pump systems are powered by
electricity and use the heat extracted from the air to generate thermal energy
to make hot water.
A heat
pump is an efficient and environmentally friendly system that converts one unit
of electrical energy into four units of thermal energy, resulting in
significant cost savings compared to alternative heating systems that use
electricity or gas.
The
unique ability of CO2 heat pumps to produce 90°C hot water makes them suitable
for a wide range of industrial, commercial and residential projects, including
food processing plants, dairies, shopping centers, apartments, hotels,
restaurants, hospitals, aged care, entertainment and education facility. CO2
heat pumps can also be used with a high degree of safety, as the absence of
combustion reduces the risk of fire.
CO2 heat
pumps use supercritical carbon dioxide as the refrigerant instead of the more
traditional ammonia or haloalkane ( R134A ) refrigerant gases. The technology
provides a means of saving energy and reducing greenhouse gas emissions. From
the energy output side, the operating characteristics of heat pumps differ from
conventional systems (such as electric/gas/oil boilers or electric heaters).
For conventional systems, 1kW of energy input provides less than 1kW of output
energy or heat. With a CO2 heat pump system, for every 1kW of input energy
consumed, an average of 3.9 times the input is produced as output energy or
heat by extracting heat from the outside air.
Generalize
Produces
90°C hot water with an average COP of 3.9, making the Revere™ CO₂ heat pump the
ideal energy efficient domestic hot water and space heating system for
industrial, commercial and residential applications. This ability to convert
1kW input energy to 3.9kW output energy represents an ongoing economical and
sustainable solution for water heating.
Designed
for space and energy efficiency
The
LM-090Y5 has a heating performance of 90 kW and is designed to reduce high hot
water supply costs and large space requirements, which are unavoidable in
facilities that require a large amount of hot water supply.
The
Y-frame construction reduces power consumption and allows units to fit
together. Heating performance can be switched between three modes to adjust the
energy to suit how you use your hot water, and performance won't degrade in
temperatures as low as -15°C.
This
flexible system is suitable for a variety of facilities that use large
quantities of hot water and is durable enough to provide a steady supply of hot
water for long periods of time.
Features
and Benefits:
1.
Flexible - the same system can be used for both space heating and domestic hot
water
2.
Ultra-quiet operation – 60dBa
3. Does
not burn - reduces fire risk
4. For
ΔT up to 60°C (90°C flow, 30°C reflow)
5.
Suitable for all climatic conditions - suitable for ambient operating
temperature from -5°C to 43°C (special units available for -15°C or -20°C)
6. Safe
- non-flammable CO2 refrigerant
7.
Programmable - can be set to operate during off-peak hours to benefit from
low-cost power
8. 30%
space saving due to Y-frame design (CHP-80)
9.
Versatile - Suitable for a variety of uses, from small facilities to large
buildings requiring hot water or heating
10.
Environmentally friendly – CO2 heat pumps use natural CO2 refrigerant. This
refrigerant has a Global Warming Potential (GWP) of approximately 1/1700 that
of R410 and zero Ozone Depletion Potential (ODP)
11.
Energy saving - Under optimal conditions, CO2 heat pumps achieve an excellent
coefficient of performance (up to 4.2), which equates to higher energy
efficiency. Compared with traditional electric water heaters, CO2 hot water
heat pumps can save up to 75% of thermal energy. Further energy cost savings
can be achieved by operating during off-peak hours, subject to compliance with
off-peak supply
12.
Antifreeze/Cold Zone Device - The heat pump is equipped with a defrost solenoid
valve that will open when the evaporator freezes. The hot gas will then flow
through the evaporator and melt the ice. Water cannot be stored during defrost
13.
Heating to 90°C – Due to its innovative design, the CO2 heat pump can produce
hot water up to 90°C at low and high ambient temperatures (-20°C to 43°C)
14.
One-time heating - suitable for one-time heating of water from low temperature
to high temperature (large temperature difference)
15.
Reduced storage needs - Since this hot water heat pump can heat water up to
90ºC, the size of the storage tank can be reduced
16.
Energy Saving Function - This function is an energy saving function that learns
the operation mode for the first 4 weeks to prevent unnecessary heating and
storage water temperature reduction due to natural heat loss. Use this function
to stop unnecessary boiling of the device based on operating data.
