  • Patent number: 10471390
    Abstract: A pump assisted water filtration system comprising a filter assembly, a pump assembly, and a water storage tank, which produces purified water through a reverse osmosis process and stores the purified water for later use. The pump assembly receives water from a water source and delivers pressurized water to the filter assembly. The filter assembly is configured to filter the impurities within the water, producing purified water which is collected in the water storage tank. A water flow interrupt permits the flow of water to the pump when the water level falls within the water storage tank, and blocks the flow of water to the pump when the water storage tank is full. The pump is further configured to activate when the pressure of the water flowing to the pump reaches a pump activation threshold, and deactivate when the pressure of the water falls below the pump activation threshold.

  • Patent number: 10228170
    Abstract: Embodiments of a refrigerant distributor for a micro-channel heat exchanger (MCHEX) are described. The refrigerant distributor may be configured to have orifices and/or a flow valve that are inside a header of the MCHEX. The MCHEX can be used as an evaporator in a cooling cycle, where refrigerant is distributed into the header(s) through the orifices and the flow valve may be generally in a closed state that generally prevents a refrigerant flow through the flow valve. In a heating cycle, the flow valve of the refrigerant distributor may be configured to be in an open state that allows the refrigerant to flow into the refrigerant distributor and to be directed out of the MCHEX through the refrigerant distributor. In some embodiments, the refrigerant distributor may be configured to receive liquid refrigerant, so as to eliminate the need of an expansion valve in a HVAC system.
