AW SPLIT air - water heat pumps

AW SPLIT air - water heat pumps

The SPLIT heat pumps working with the „air - water“ system are the most technically advanced type of heat pumps (acquire heat from air which applying pressure is subsequently used for water heating).

The SPLIT heat pumps are available in the output type from 6 to 36 kW
. In case higher outputs are needed, the control system allows for connecting more heat pumps in a form of cascade.

The SPLIT heat pump consist of two parts – an evaporator and a heat exchanger

Evaporator (the outdoor unit of heat pump)

Evaporator sucks the air from the ambient environment and, using a heat exchanger, it turns it into heat. One of the main benefits of this outdoor unit is silent operation - the unit is equipped with a special ultra-silent ventilators in the shape of owl wings with the rev regulation which allows for lowering the noise level (e.g. for night operation).

Indoor unit of the heat pump

The indoor unit (control system of heat pump, compressor and other components) is always placed inside the heated building. Thus it is not exposed to severe conditions of the outside which has a significant impact on the long-life of the pump. Both the outdoor unit and the indoor unit are well insulated acoustically and thermally. The noise level of the SPLIT heat pump is comparable to any modern domestic appliance.

Heating solutions, air-conditioning

The SPLIT heat pumps are often used for its universality - they can be used for heating in a building (radiators, floor and wall heating) as well as for year-round water and swimming pools heating. It has the top equipment, a built-in heat source reserve, equithermal regulation of the temperature of heating water, sophisticated functions for hot water reheating. This heat pump can be also used for air-conditioning (active cooling option) in hot summer months.

Heat pump control

Room - manager control unit

The AW SPLIT heat pump is controlled by an easy-to-use Room - manager control unit, which can be placed anywhere inside the heated building. This control unit monitors operating stages of a heat pump and it can be used to regulate the heating and hot water heating.

Web interface in the Internet browser

All our heat pumps are equipped with regulator (CP-1051) which contains a WEB - server. This regulator is a network device with its own IP address. It is possible to access the regulator remotely through the IP address and to view the web interface of the regulator control panel or the heat pump control panel in the internet browser. This connection can be made by means of PC, laptop, tablet, smart phone, etc. Heat pumps can be thus remotely controlled via these devices. The web interface of the WEB-server is very simple and intuitive, a heat pump can be thus controlled remotely.

Control by means of mobile phone

The PZP heat pumps can be also controlled via SMS commands using any mobile phone. The only requirement is to purchase a modem which is available in the section of optional accessories for your heat pumps. You will also need a SIM card to avail of this type of control.
