摘要： A heat exchanger includes a shell, a refrigerant distributor, tube bundle, and first baffle. The shell has a refrigerant inlet through which at least refrigerant with liquid refrigerant flows and a shell refrigerant vapor outlet. A longitudinal center axis of the shell extends substantially parallel to a horizontal plane. The refrigerant distributor fluidly communicates with the refrigerant inlet and is disposed within the shell. The refrigerant distributor has at least one liquid refrigerant distribution opening that distributes liquid refrigerant. The tube bundle is disposed inside of the shell below the refrigerant distributor. The first baffle extends downwardly from the refrigerant distributor at a top of the tube bundle to at least partially vertically overlap the top of the tube bundle. The first baffle is disposed laterally outwardly of the tube bundle toward a first lateral side of the shell.

摘要： The present invention relates to an absorption chiller which comprises an evaporator, an absorber, a regenerator and a condenser and has an absorbing solution and a refrigerant circulating. A heat transfer pipe, which is provided on one or more of the evaporator, absorber, regenerator and condenser, is comprised, and a ductile stainless steel pipe, which has 1% or less of delta ferrite matrix structure on the basis of the grain size area, is applied to the heat-transfer pipe. Therefore, copper-level flexibility can be obtained in comparison with an existing stainless steel pipe.

摘要： A method of operating an HVAC system comprising a first and second portion of evaporator circuits, the first portion being adapted to receive refrigerant from a first refrigerant path and the second portion being adapted to receive the refrigerant from a second refrigerant path. The method comprises determining a first value that is calculated based on a speed of an air blower and a total capacity of the HVAC system, and the air blower is operable to push a minimum volume of air in to the enclosed space. The method further comprises upon determining that the first value exceeds a cooling threshold or that the first value exceeds a dehumidification threshold, instructing a valve to close such that refrigerant cannot flow to the first portion of evaporator circuits.

摘要： The present invention relates to a high-efficiency air water system for a tropical climate, including a filtration system, in which an evaporator is provided in an internal accommodating space of a main body, and a condenser is installed in a perforated portion formed passing through a side wall of the main body, so that air cooled in the main body is used to dissipate heat generated in the condenser so as to improve dehumidification efficiency. The configuration of the high-efficiency air water system comprises: an air suctioning unit that suctions and supplies external air; a water generating unit that condenses moisture from the air supplied from the air suctioning unit to generate water; and a water purifying unit that filters and purifies the water generated by the water generating unit to a drinkable or usable state. The water generating unit is constituted by including a main body having an accommodating space provided therein, and an evaporator, a hopper, a water storing part, a condenser, and a compressor are installed in the main body.

摘要： An outdoor heat exchanger of an outdoor unit includes a main heat exchanger portion and an auxiliary heat exchanger portion. In the main heat exchanger portion, refrigerant path groups are formed. In the auxiliary heat exchanger portion, refrigerant paths are formed. The refrigerant path in the auxiliary heat exchanger portion, which is located closest to the main heat exchanger portion, is connected to the refrigerant path group in the main heat exchanger portion, which is disposed in a region where a wind velocity of the outdoor air passing through the main heat exchanger portion is relatively high. In addition, the refrigerant path is connected to the refrigerant path group. The refrigerant path is connected to the refrigerant path group. The refrigerant path is connected to the refrigerant path group.

摘要： An ice machine for an ice-based thermal storage system comprises a plurality of pillow plates arranged in a plate bank, wherein each of the plurality of pillow plates includes an inlet connection and an outlet connection, with the respective inlet connections connected to a feed header, and with the respective outlet connections connected to a suction header. A water distribution pan is positioned at a top of the plate bank, and a tank is positioned below the plate bank. As an evaporator, the ice machine causes ice to form on the pillow plates, which then falls into the tank. As a condenser, the ice machine transfers heat to water flowing over the pillow plates, such that water at an increased temperature falls into the tank and melts the ice in the tank.
