Heat pump for heat supply of individual housing

        A significant part among heat pumps is occupied by small heat pumps used to supply heat and hot water to individual houses and with heat productivity of about 10 kW. The sources of low-potential heat are soil (5....15°С) and subsoil waters (8...15°С). The temperature of water heated in heat pump to provide hot water supply is no less than 60°С. If the water is used only for heating, the temperature may be lower. If the required temperature is 55°С and below, Freon R22 can be used as the working substance.
    In heat pumps it is principally important to establish counter-current heat exchange in the devices, especially in the condenser. It is achieved in the devices with condensation and boiling of the working substance Freon R22 in tubes.
    The exhibited heat pump has got “tube within tube” heat exchange devices of a new type with surfaces edged by deforming cutting technology.
    Heat carrier (water) passes inside the inner tube and the working substance in side the inter-tube edged channel. Alternatively under these circumstances plates-type devices with countercurrent system can be used (boiling and condensation of the working substance in slit channels of the plates).

Production of liquid natural gas

    Currently the EKIP company is engaged in financing and construction of a natural gas liquefying system based on CNG-500 with a productivity of 1 ton per hour at the Moscow Gas Processing plant. The production of LNG is planned to begin in the 2nd quarter of 2003.
    Joint projects are being planned with Mostransgaz and Lentransgaz to build a network of CNG stations equipped with natural gas liquefying systems to deliver LNG, CNG and LPG at one gas station.
    Besides there has been developed a project of gas liquefying system at gas-distributing station in Naro-Fominsk (Moscow region) with LNG to be produced at GDS in 2003-2004.

Multy-fuel gas stations

    The EKIP (EKIP-GAZ) company is designing equipment of the first in Russia multy-fuel gas station to distribute LNG, CNG as well as LPG. The station is going to be equipped with a tank for LNG. CNG will be derived from LNG by gasification. The construction of the gas station is planned in 2003-2004.

Equipment for natural gas

    EKIP is actively involved in the issues of utilizing natural gas as motor fuel. We are designing a cryogenic gas tank and equipment for motor vehicles. A number of variants of production of some parts of the gas system for motor vehicles is considered as well. Currently the work is being carried out to build own LNG, CNG, LCNG and LPG distributors.
