PURPOSE OF HEAT PUMP SCOPE OF DELIVERY

2 PURPOSEPUMP OF HEAT

2.1 Application

The air-to-water heat pump is designed for use in existing or newly built heating systems.

The heat pump is designed exclusively for the heating and cooling of heating water!

In the heating mode, the heat pump is suitable both for mono-energetic and bivalent operation at outdoor air temperatures down to -20 oC.

In the continuous mode of operation, a heating water return temperature of more than 18 °C must be maintained in order to ensure proper defrosting of the evaporator.

The heat pump is not designed for any increased heat demand during the drying phase of new buildings; the additional heat demand must be met by special appliances to be supplied on site. For the structural drying of new buildings in the autumn or winter it is recommended that an additional electric 3 heating element (available as accessory) be installed.

In the cooling mode, the heat pump is suited for air temperatures ranging from +15 °C ... +40 °C.

It can be used for passive and dynamic cooling applications alike. The minimum water temperature is +7 °C.

CAUTION! The unit is not suited for operation with a frequency converter.

2.2 Principle of Operation

Heating

Ambient air is drawn in by the fan and passed over the evaporator (heat exchanger). The evaporator cools the air, i.e. it extracts the heat it contains. In the evaporator, the heat removed is transferred to the working fluid (refrigerant).

With the aid of an electrically driven compressor, the absorbed heat is "pumped" to a higher temperature level through pressure increase and given off to the heating water via the condenser (heat exchanger).

The desuperheater, mounted upstream, enables domestic hot water to be produced simultaneously or separately.

In so doing, electrical energy is used to raise the heat of the environment to a higher temperature level. Due to the fact that the energy extracted from the air is transferred to the heating water, this type of appliance is referred to a air-to-water heat pump.

The air-to-water heat pump consists of the following main components: evaporator, fan and expansion

valve as well as the low-noise compressor, a desuperheater, a condenser and the electric control unit.

In the case of low ambient temperatures, air humidity may accumulate on the evaporator in the form of frost impairing the heat transfer. The evaporator is automatically defrosted by the heat pump, if required.

Cooling

In the "cooling" mode, the operating process of evaporator and condenser is reversed..

The heating water transfers the heat to the refrigerant via the condenser that is now working as the evaporator. In the compressor the temperature of the refrigerant is raised, and the heat is rejected to the ambient air via the condenser (in the heating mode the evaporator).

Via the additional heat exchanger, the waste heat can also be used for hot water consumers such as domestic hot water, swimming pool or bathroom heating applications.

LA16ASR specifications

The Dimplex LA16ASR is an innovative heating solution designed to deliver both efficiency and comfort in a compact form factor. This model is particularly aimed at residential users seeking effective space heating without the bulk of traditional radiators.

One of the standout features of the LA16ASR is its advanced convective heating technology. This allows for quick warming of the living space, creating a cozy environment in no time. The convection process heats air around the unit, which then rises and circulates throughout the room, providing a consistent temperature without creating cold spots. This mechanism not only enhances comfort but also optimizes energy use.

Another key characteristic of the Dimplex LA16ASR is its integrated thermostat. The built-in thermostat allows users to set their desired temperature easily, ensuring that the heater operates efficiently by maintaining the preset level. This feature minimizes energy consumption, making the unit an eco-friendly choice while also reducing utility bills.

The design of the LA16ASR is sleek and modern, making it suitable for a variety of room decors. With a compact size, it can fit seamlessly into tight spaces without compromising performance. The heater is also lightweight, making it easy to move from one room to another as needed.

Safety is paramount in HVAC systems, and the LA16ASR does not disappoint. It is equipped with overheat protection, automatically switching off the unit if it reaches excessively high temperatures. This feature provides peace of mind, particularly in homes with children or pets.

In addition to its impressive heating capabilities, the Dimplex LA16ASR is designed for quiet operation. Unlike traditional heaters that can be noisy, the LA16ASR operates without the disruptive hum, allowing for a serene environment, ideal for both homes and offices.

Finally, the LA16ASR is energy efficient and environmentally friendly. Its design and technology work together to minimize energy waste while providing immediate heat, making it an excellent investment for those looking to cut down on energy costs without sacrificing comfort.

In summary, the Dimplex LA16ASR combines effective heating technology with a modern design, safety features, and energy efficiency, making it an outstanding choice for anyone in need of a reliable heating solution.
