Half-industrial systems GREE: EVERYTHING YOU NEED corporate customers
Unlike conventional heating systems based on the combustion of gas or liquid fuel , as well as direct transformation of electric energy into thermal energy in the heat pump is not consumed to produce heat , but only its transfer from the external environment . That’s what makes these systems an attractive solution for space heating and hot water at sites with limited energy resources.
Heat pumps ” Ekodan ” manufactured by Mitsubishi Electric, intended for individual heating and hot water town houses and similar buildings that do not have access to such a relatively cheap energy sources such as gas and liquid fuels , as well as substantially limited in the electrical power input .
Maximum heat output of a system of ” Ekodan ” is 14 kW, which is commensurate with modern heat loss of individual country houses. To increase the power provided an opportunity to cascade systems.
Heat pump ” Ekodan ” consists of two units : the outdoor unit , which is largely similar to the outdoor unit air conditioner, and indoor unit – hydronic heating water performing . Units are equipped with all the necessary control devices , control and regulation . Installation of such a system is no different from conventional air conditioning installation – cope with it any HVAC company . Excludes complex design heating and DHW system of separate components: a hydronic distribution system simply connects to the sanitary water use , as well as forward and reverse heating pipes .

Two years ago the management of the concern Systemair was decided to consolidate the production of all heating equipment under the brand Frico. On the one hand, it significantly expanded the possibilities, but on the other – significantly increased the responsibility for the possible failure of the local , including Ukrainian , markets.
At the same time the company’s strong growth came through acquisitions and air curtains manufacturers (Gelu, Shearflow, Tekadoor) in Europe . Partially their products poured into the main lineup, expanding its capabilities, partly dubbed the already existing model curtains Frico.
Thus, by the beginning of 2012 under the brand Frico produces more than 390 different air curtains . They were made in different countries, in different companies , with different technologies and different hardware components .
This circumstance prompted Systemair engineers to develop a new generation of air curtains that would connect a results of the most recent studies with new technological possibilities .
According to specialists, the diversity of the manufactured equipment could be without prejudice to the consumer to replace 150 models , making them the most versatile. Primarily developed product series PA3500 and PA4200, designed to replace the hangings series AS300/400 , AD300/400 and AG/AGV4000. Horizontal model with appropriate accessories can be connected in a continuous line , installed vertically and join column or placed in a suspended ceiling . Dimensions curtains from 1 to 3 m in increments of 0.5 m equipment available in versions without heating (A) , with electrical ( E) and hot water coolant with different parameters (WH, WL, WLL).

As is known , Ukraine not apply to countries with efficient use of natural resources . However, over the years , this problem becomes more acute. Significant place in wildlife occupy the rational use of water resources is .
Today, the only tool stimulating the end user to save resources (water , energy ) are tariffs, which significantly outpaces growth official inflation. But do not forget about the water suppliers , who also have to pay the state at the relevant rates for use of water resources . When water is taken and reset rates above the established limits defined by the state, increased significantly.
Therefore, the main task facing the water distribution system is to ensure a stable water supply , water management , which can be very scarce , detection and elimination of pipe rupture , leakage reduction and keeping operating costs as low as possible . Here one of the most effective solutions is to upgrade water systems engineering , which involves the use of high-tech pumping equipment together with modern automated control systems .

Semi- equipment segment today – one of the most promising and fastest growing areas in the Ukrainian market climate . Scope ” poluproma ” – commercial and industrial sites , restaurants, cafes, hotels and, of course , business centers . Office space being built regardless of the season , so the system is almost always semi- stable demand . To solve the problems such objects conditioning Gree company offers a wide range of equipment for commercial purposes capacity from 12 to 150 kBTU ( from 3.5 to 40 kW).
Semi Gree air conditioners adapted to Ukrainian power grids , have control of phase sequence and phase unbalance protection . Outdoor units with power from three-phase AC equipped with a compressor crankcase heater . The refrigerant used ozone-safe refrigerant R410A . Among other features – automatic restart with all settings , low noise , the ability to control via the central controller and combining up to 16 central controllers in the same group , corrosion-resistant coating of the exterior unit.
Fig . 1. Cassette Split Systems Gree ( compact ) – the ideal solution for residential and small offices.
Cassette indoor units , wall, ceiling or duct connected to a universal type outdoor units .
Outdoor units with power from three-phase AC power available in standard and low-temperature performance , allowing work in cooling mode at an outside temperature of -30 ° C. This greatly enhances the use of semi- Gree air conditioners and allows to operate the equipment .
Cassette indoor units and units are equipped with built-in channel-type drainage pump condensate with a lifting height of 750 mm from the axis of the drain pipe. Also in these blocks are predformovannye inputs for connecting duct supply air treated . Continue reading
