cascade heat pump uses no less than two coolants, one compressor, with coolant pipes connecting the compressor, condenser, dephlegmator, evaporation-condenser, heat regenerator, evaporator, and throttle structur
The central heating control system is for use where the water or other liquid is pumped through a circuit between the boiler and one or more radiators. Pump speed is varied as a function of the difference in temperature between the actual value measured near a heat emission point and a refer...

Soundproofing solutions block sound by creating a barrier of dense mass between one area and the next. To clarify, let’s examine the components involved in this process:Mass –One of the popular soundproofing methods is to add mass to the walls, ceilings, and floors. Heavy materials, such...
Using the difference between the exhaust pressure and the bearing pressure to supply oil, the compressor is not set up with the oil pump to simplify the lubricating oil supply system. Oil mist eliminator The inhaled gas passes through the motor first and is compressed and discharged in the cyli...
and the difference between venous-to-arterial CO2 content calculated with the Douglas' equation (ΔCCO2D) over ΔO2 ratio (ΔCCO2D/ΔO2) and their abilities to reflect the occurrence of anaerobic metabolism in two experimental models of tissue hypoxia: ischemic hypoxia (IH) and hypoxic hypox...

Interactions between food and saliva govern complex mouthfeel perceptions such as astringency. Herein, we present a study of the interactions of salivary proteins with the main pea protein fractions that are obtained by isoelectric and salt precipitation (legumin-rich, vicilin-rich and albumin-rich fr...
