R32 REFRIGERANT

R32 Refrigerant

ECOLOGICAL

R32 refrigerant has a very low GWP of 675. Compared to R410A, which has a GWP of 2088, R32 has a relatively low environmental impact – its global warming impact is as much as three times smaller. It also has no negative impact on the ozone layer, as evidenced by an ODP factor of O. In addition, unlike R410A, R32 is a homogeneous (single-component) refrigerant, so it can be recycled. All SEVRA heat pumps operate with the latest environmentally friendly refrigerant R32, which, compared to the commonly used R410A refrigerant to date, has higher efficiency and a lower greenhouse effect coefficient. It also does not damage the ozone layer.

HIGH EFFICIENCY

Due to its thermodynamic properties, R32 refrigerant is more efficient than R410A. The installation requires less refrigerant. In addition, R32 increases the energy efficiency of the device by up to 10%

SAFE

R32 refrigerant has low toxicity, so it guarantees high safety of use.

HEAT PUMP

HOW
A HEAT PUMP WORKS

The vast majority of air-to-water heat pumps are classified as renewable energy sources and are now considered the most efficient heating technology. An air-to-water heat pump is a device that uses heat accumulated in the air for heating or cooling and domestic hot water preparation. The method of operation of a heat pump, contrary to appearances, is not complicated and is based on a well-known mechanism used, for example, in refrigerators. The most important components of the pump are the compressor, expansion valve, condenser and evaporator. The entire process is made possible by a refrigerant. Refrigerant is nothing more than a liquid that, circulating in the internal system, boils at low pressure and temperature, taking heat from the environment.

Then there is an increase in pressure and temperature in the system, thanks to the compressor, the refrigerant turns into a gaseous form, and then goes to the condenser and gives up heat to the system. After that, the liquid refrigerant passes through the expansion valve, where the pressure and temperature drop, and the process begins again. If the pump has an integrated cooling function then the process is reversed – the refrigerant recovers heat from the water and discharges it outside.

HEATING

MODERN HEATING

BUILDING A NEW HOME?

. When building a new home, one of the key decisions we need to make is choosing the right heating system. Such a decision does not depend solely on our preferences, but also on the applicable regulations. One of the most popular modern and cost-effective heat sources that meet strict standards are air source heat pumps. In the case of newly built houses, it is worth remembering that heat pumps paired with a photovoltaic installation provide a source of free power. Therefore, SEVRA ECOs HEAT pumps are a safe investment for years.

MODERNISING YOUR HOUSE?

In an era of stricter environmental standards, when considering energy-efficient thermal modernization, investors most often opt for air-source heat pumps. This choice is dictated by a number of factors, the most important of which is to achieve lower heating costs for the building. An additional argument in favor is the possibility of combining the heat pump with a photovoltaic installation, which allows to obtain electricity from free solar energy. SEVRA ECOs HEAT pump is an economical and ecological alternative.

FEATURES

FLOOR HEATING

Plane heating, also known as underfloor heating or wall heating, is an increasingly popular form of heating in many homes and commercial buildings. There are a number of reasons why it can be considered the most cost-effective form of heating, some of which include: greater thermal comfort, energy savings, lower heat loss and longer life than traditional radiators.

ECOLOGICAL R32 REFRIGERANT

SEVRA ECOs HEAT pumps work with environmentally friendly refrigerant R32, which has a low GWP coefficient, meaning that it does not damage the ozone layer. When we buy these devices, we are guaranteed that we are choosing the safest solution for both us and the environment.

DOMESTIC HOT WATER
UP TO 60°C

.

SEVRA ECOs HEAT heat pump is capable of preparing water for domestic use up to 65oC, even at extremely low outdoor temperatures.

INVERTER TECHNOLOGY

Inverter technology is an advanced technology used in many types of electrical appliances, such as air conditioners, heat pumps, refrigerators and many others. It allows infinite regulation of the device’s performance, which has many benefits, both in terms of energy savings and user comfort.

ENERGY EFFICIENCY A+++

Newly designed two-stage rotary compressor with DC inverter provides low noise and wide capacity range.

FAST DHW FUNCTION

The term DHW comes from the English language and means “domestic hot water,” which is nothing more than domestic hot water. In the case of SEVRA ECOs HEAT pump, the function is used to force the system into DHW mode when the user urgently needs hot water.

BACTERIAL DISINFECTION

Legionella pneumophobilla bacteria are found in the natural human environment, including water. Under favorable conditions, they multiply very quickly. They take a particular liking to water and air conditioning systems. The intensive growth of Legionella bacteria in drinking water poses a threat to human health. SEVRA ECOs HEAT heat pump has a function that fights these bacteria.

WATER TEMPERATURE ADAPTATION

A heat pump is an advanced device that is an increasingly popular choice for heating and cooling buildings. One of its key strengths is its ability to automatically define and maintain the optimal water temperature to ensure the utmost comfort for users.

ECO MODE

The ECO mode on SEVRA heat pumps is a setting that seeks to save energy by optimizing the unit’s operation. In this mode, the heat pump operates more economically, adjusting the heating output to current conditions and heat demand. As a result, users can enjoy thermal comfort with lower electricity consumption, which translates into financial savings and a positive impact on the environment.

VACATION MODE

When the user goes on vacation, the vacation function can be used to protect the unit from frost damage depending on the climate. When the vacation function is active, the unit will operate in heating or DHW mode with a low set temperature (Default: 25°C, range: 20-25°C) for the set period.

QUIET OPERATION

Quiet operation of outdoor unit below 45dB and indoor unit below 31dB.

SMART GRID NETWORK

SEVRA ECOs HEAT pumps according to the SG Ready label have the ability to connect, through appropriate controls, to the smart electrical grid.

SAFETY

Heat pumps are a safe source of heating because they do not use the process of burning fossil fuels, which eliminates the risk of explosions or toxic gas emissions. In addition, heat pumps work by converting heat energy from the environment, which means there is no need to store or transport hazardous substances. In addition, modern heat pumps are equipped with advanced monitoring and safety systems, which increases their reliability and minimizes the risk of failure. These features make heat pumps a safe and environmentally friendly solution for heating and cooling buildings.

EMISSION-FREE

Heat pumps are emission-free devices, meaning that they do not generate emissions that are harmful to the environment or human health during their operation. The emission-free nature of heat pumps is due to the use of thermodynamic principles and heat transfer processes that do not require the combustion of fossil fuels such as gas or fuel oil to provide heat or cooling to buildings.

MAINTENANCE-FREE

The maintenance-free nature of heat pumps means that they are easy to maintain and do not require frequent repairs or user intervention. This saves time and money by avoiding the need for regular supervision of the unit. SEVRA heat pumps operate efficiently and reliably, which ensures stable indoor temperatures while minimizing the costs and hassles associated with their use. This is a convenient, economical and comfortable solution for users.

FAST AND EASY INSTALLATION

The speed of SEVRA heat pump installation is a huge benefit to building owners. The heat pump installation process is typically much shorter than with traditional gas or oil boiler-based heating systems. This means less disruption and less inconvenience associated with the installation work. In addition, the shorter installation time translates into lower labor costs and less inconvenience for residents.

VERSATILE APPLICATION

The SEVRA heat pump is a versatile unit that can work effectively with different types of heat consumers, making it ideal for both residential and commercial applications. In addition, SEVRA heat pumps can be used in bivalent systems, where they work together with other heat sources, such as a gas boiler, solar installation. In such cases, the heat pump can act as the main heat source, while other equipment is used as a backup in case of extremely low temperatures or during maintenance.
