There is provided a polyester elastomer foam having a micro and uniform cell structure. The polyester elastomer foam is formed by allowing a polyester elastomer composition containing a polyester elastomer and a surface-treated inorganic substance (except hydroxides) to expand. A residue on a 166 mesh sieve in the surface-treated inorganic substance (except hydroxides) is preferably not more than 0.01%.

摘要:
Heating equipment, including a first heat exchanger, a compressor, a second heat exchanger, and a first expansion valve that decompresses a refrigerant flowing from the second heat exchanger to the first heat exchanger, are connected so as to circulate the refrigerant. A third heat exchanger provides heat of the refrigerant flowing from the second heat exchanger to the first heat exchanger to the refrigerant flowing from the first heat exchanger toward the compressor. An injection circuit merges part of the refrigerant flowing from the second heat exchanger to the first heat exchanger with the refrigerant that is sucked by the compressor. An injection expansion valve is installed in the injection circuit and decompresses the refrigerant flowing in the injection circuit. A fourth heat exchanger is installed in the injection circuit to supply heat of the refrigerant flowing from the second heat exchanger toward the first heat exchanger to the refrigerant flowing in the injection circuit.

摘要:
An air conditioning apparatus has plural indoor units having: plural heat exchangers; and flow controllers respectively corresponding to the heat exchangers. In each of the indoor units, one heat exchanger is used as a condenser, and another heat exchanger is used as an evaporator, thereby causing the indoor unit to perform a temperature and humidity controlling operation. An indoor unit(s) which is not set to perform the temperature and humidity controlling operation may be caused to perform a heating operation or a cooling operation. Capacity controls on the condensers and the evaporators are performed by corresponding flow controllers. Gas refrigerants ejected from plural heat exchangers serving as evaporators are joined together, and then distributed to plural heat exchangers serving as condensers.
摘要:
In a refrigerating air conditioning system using refrigerant such as CO2 used in a supercritical area, a highly efficient refrigerating air conditioning system is provided by adjusting the amount of refrigerant in a radiator which contributes to the efficiency of the system stably and quickly. During heat utilizing operation, the superheat at the exit of an evaporator is controlled to a predetermined value by controlling the opening of an expansion valve provided on the upstream side of the evaporator, and an expansion valve is controlled so that the state of refrigerant in a connection pipe on the high-pressure side becomes a supercritical state. In this state, a flow rate control valve is controlled to change the density of the refrigerant stored in a refrigerant storage container and the amount of refrigerant existing in the radiator is adjusted. A target high-pressure value and a target value of the radiator exit temperature are set and the capacity of the compressor is controlled to obtain the target values, and the amount of refrigerant existing in the radiator is adjusted by the refrigerant amount adjusting circuit.
