As energy costs and regulatory demands for system efficiency increase, thermostatic expansion valves (TXVs) are replacing capillary tubes, particularly in residential air conditioning and heat pumps.

The capillary tube — the simplest of refrigerant controls — is the most popular method for metering refrigerant flow from the condenser to the evaporator in compression-type refrigeration systems.

SINOLANC radiant ceiling system can not only be used for cooling, but also for energy-efficient heating. The implementation of ceiling heating and cooling in one system reduces operating costs ...
