ELECTRIC APPLIANCES Gree is a manufacturing company that was founded in 1991 and quickly got the world's largest air conditioner manufacturer integrating research, development, production, sales and service. Six factories produce 20 series, 400 kinds and 7000 models of domestic and commercial air conditioning to satisfy all the requirements of consumers. Gree is the largest Chinese manufacturer of air conditioning equipment and is co-owner of Daikin factories. In factories, Gree units are manufactured for a company named Daikin, one for Artel, Sinclair, and many others. Using the latest technology, precise work and 3,000 new patents gives the best results in facilities Gree.

How to navigate the product catalog
To help you navigate the extensive product range of Gree, we prepared a small guide to our products. We start by explaining the series of names and naming of products. Air conditioning and heating technology is divided by use and size into three categories. first The first group called " UNITAR " (loosely translated as "unit") are included air conditioning sets, which always consist of one indoor and one outdoor unit. Products in this series are designed for cooling and heating rooms, offices, etc. The internal units are in various designs and sizes according to use. This includes in particular the classic wall unit or cassette (in false ceilings). There is also a unit ceiling - Ceiling (can be mounted on a ceiling or wall as a heating element), then box (standing) and to channel air system with air tubing. Each of these air conditioner is connected via a connecting pipe to the outdoor unit that must be placed in an open space freely accessible to fresh air. This part can not be placed in closed rooms or attic spaces. In the first section , "Wall air conditioning" of this group are all listed as wall models as standard with the compressor FixSpeed and with DC Inverter technology. In the second section called U-Match are other cassette, ceiling, channel and box models, again in the standard version and DC Inverter. second In the second group called "VARIABLE MULTI VRF" find air conditioning kits, where you can connect one outdoor unit multiple indoor units of different type. The air conditioning can be used in family houses, offices and administrative buildings. For smaller groups with the ability to connect up to 5 indoor units to one outdoor use of equipment subcategory FREE MATCH . It is necessary to select the types and sizes of indoor units and their power to choose a suitable outdoor unit. If you need to connect more than one air-conditioned indoor pool, choose from the other sub-units "GMV MULTI VRF SYSTEM" . Here again, we choose for each room air conditioner according to overall performance and assign an outdoor part. We have modules with output power up to 180kW cooling - heating. third The third category of "HEAT PUMPS AIR - WATER" includes equipment for heating domestic hot water, heating or cooling.
Unique HOME GMV is a comprehensive energy solution for your house. To one outdoor unit can be connected HydroBox (module production of hot water for heating and preheating domestic hot water) and the assembly of up to nine air conditioning units for cooling and heating rooms and rooms. "Versati DC Inverter" is a heat pump air - water in the inverter design indoor unit for hot or cold water for heating or cooling.
Glossary - what is it?
Air UNITAR - product line of air conditioning units for small applications. The product contains one indoor and one outdoor unit. It is available in wall-mounted, cassette, ceiling-suspended or channel. You can choose a standard compressor technology or technology DC Inverter.
Air U-MATCH - subcategory of the "UNITAR" find cassette, ceiling, channel and box with standard air conditioning and DC Inverter technology.
Air GMV - VRF (Gree Multi Variable - Variable Refrigerant Flow) in translation is called a system with variable flow of refrigerant in circulation. (Sometimes you will find a sign VRV, which is identical and is based on the phrase "variable refrigerant".) All compressors in these facilities are DC Inverter technology with variable speed. In the case of connecting a number of indoor units to one outdoor this system must provide the exact amount of refrigerant according to the actual load requirement of indoor units. The user can evaluate a system with one outdoor air conditioning unit on which you can connect to the satisfaction of multiple indoor units. For large systems, the pipe as needed rozbočuje usually near the indoor unit and continues to the next unit, etc.
FREE MATCH - product group from VRF family, for use in smaller homes or businesses. Outdoor units are furnished with DC Inverter technology with controlled speed compressor according to the model it can be connected to 5 indoor units with total output up to 12kW. Connecting pipe is maintained at these reports from each of the indoor unit to outdoor separately.
VERSATI heat pump air - water systems have two parts to the outdoor unit (like air), where the compressor circuit with energy collected from outdoor air and indoor unit turns into hot water for heating and hot water. Then we can bring to the floor heating system or heating system, for example, with appropriate fan Fan-coil radiators. Of course DC Inverter technology is a system of cooling water to air-conditioning system.
Heat pump HOME GMV unique device comprising all the advantages of VRF and heat pump systems in one. DC Inverter technology, along with precise microprocessor control is inevitable. The outdoor unit is connected to distribution to VRF air conditioning system with a 9-indoor units. In this circuit, we provide air-conditioning facility. The outdoor unit is also connected HydroBox - a module that produces hot water for heating or hot water. In cooling mode, hot water production with the device operates with a COP (the ratio of energy embedded and acquired) to 6.6.
Technology FixSpeed - (also known as ON / OFF or standard) technology, this compressor can be found in the basic lines of air conditioning units. In practice this means that the compressor is run as required cooling or heating and running at full capacity. After reaching the set temperature off and on again the next request. The units are simple to use without complicated circuits, but on and off is significant.
DC Inverter technology (inverter DC) allows you to smoothly control the speed of the compressor. This solution can very precisely control the desired power conditioning and allow inaccurate and non-economic overheating or supercooling. Accuracy of performance management will save energy costs and the device operates without electrical and mechanical shock.
COP - is the ratio of embedded energy than the energy obtained in the heating mode, air conditioning and heat pumps. For example, COP = 3 means that the consumption of 1 kW of electric power facilities shall 3kW of heat. A higher number (ratio) will give us greater savings. COP varies depending on the system and all operating temperatures.
EER - is the ratio of embedded energy than the energy obtained in the cooling mode, air conditioning and heat pumps. For example, EER = 3.5 means that the consumption of 1 kW of electric power equipment will issue 3.5 kW cooling. A higher number (ratio) will give us greater savings. EER again varies depending on the system and all operating temperatures.
Refrigerant R410A - effective refrigeration fluid for use in air conditioners and heat pumps. This compound has the best-known physical properties required for use. With the refrigerant R410A air conditioners come in energy class A and A +. Other used refrigerants such as R407C, R404A or R134a complex below the quality level of refrigerant R410A.
How to choose air conditioning?
As a first step we need to find out how much power air conditioning or heat pump needed.
As a first step we need to find out how much power we need air conditioning. For cooling, use a very simple method. We will find the volume of space that we want to cool (m3). This value is multiplied by a coefficient C and obtain the required cooling capacity in kW. The coefficient C has a value of 0.02 (cold room without sun, etc.) to 0.05 (extremely sunny south room). The result is necessary to add heat sources that may in their own room. For example, 4 computers (4x 0.2 kW heat) plus 4 persons (4 x 0.05 kW of heat) added to the overall result and we get the desired output in kW. Example: Office on the south side of 36 m2 with ceiling height of 2.7 m in summer strong heat, three people, three computers (36 x 2.7 x 0.04) + (3 x 0.05) + (3 x 0.2) = 4638 kW cooling capacity air conditioning needed for any advice call us any time.
