Inverter heat pumps with scroll compressor

The model range of TICA company includes inverter heat pumps with a scroll compressor with a capacity from 12 to 20 kW: 5 of them — with a ceiling indoor unit, 3 — with a wall unit. Water consumption varies from 2.06 to 3.44 cubic meters/h (depending on the model). Indoor units can work both for heating and cooling and can be connected to underfloor heating systems, fan coils, radiators, low-power ventilation units. The following modes are provided: floor heating, heating or cooling using connected fan coils, maintaining the temperature of the underfloor heating. In addition, self-diagnosis functions are implemented (when a malfunction is detected, the error code is displayed on the touch screen), automatic switching on and off of the thermal inverter pump (set using a timer), automatic start with the current settings after power is restored, intelligent and powerful defrosting. The user can restrict access to the management system by entering a password. The TICA inverter heat pump for water provides for the possibility of working in three silent modes (day and two night — automatic and forced), they also have 9 noise reduction stages. The maximum noise level during operation of the indoor unit is 37 dB(A). This is less than in the library's reading room. Each inverter heat pump (air-water) is equipped with a spiral EVI compressor manufactured by Emerson Copeland (USA), a shielded variable frequency water pump manufactured by Grundfos (Denmark), one or two fans and the same number of brushless DC motors from Shibaura (Japan).
