摘要： The present invention provides a vehicle air-conditioning system comprising: a pair of evaporation units which cause heat exchange between a refrigerant and air, and which are arranged to be spaced apart from each other so as to discharge cold air in different directions; one expansion valve, which expands a low-temperature and high-pressure refrigerant so as to supply same to the evaporation unit; an inlet pipe in which the refrigerant of the expansion valve moves to a first evaporation unit; a first moving pipe in which the refrigerant having circulated through one region of the first evaporation unit moves to a second evaporation unit; a second moving pipe in which the refrigerant having circulated through the second evaporation unit moves to the first evaporation unit; and an outlet pipe through which the refrigerant having circulated through the first evaporation unit flows out.

摘要： Example embodiments of the present disclosure relate to a climate control system and methods for controlling the system. Some embodiments include a system that includes a refrigerant circuit with both a main circuit and a bypass circuit, where the main circuit directs the refrigerant fluid from a compressor to a first heat exchanger, a metering device, a second heat exchanger, and an accumulator, and the bypass circuit selectively directs a portion of the refrigerant fluid to a third heat exchanger. The bypass circuit includes a bypass control valve and a bypass metering device, the bypass control valve controlling the flow of the portion of the refrigerant fluid to be directed to the third heat exchanger, and the bypass metering device lowering the temperature of the portion of the refrigerant fluid before the portion of the refrigerant fluid enters the third heat exchanger. The third heat exchanger may be located proximate the accumulator.

摘要： An object of the present invention is to prevent cavitation in a refrigerant pump from occurring due to a decrease in a net positive suction head in a cooling device.
A cooling device of the present invention is a cooling device using a refrigeration cycle in which a refrigerant is circulated through a heat receiver (1), a compressor (2), a heat radiator (3), and an expander (4), and includes a tank (5) that separates the refrigerant supplied from the expander (4) into a gas phase refrigerant and a liquid phase refrigerant, a pump (6) that sends the liquid phase refrigerant separated in the tank (5) to the heat receiver (1), and a control unit (7) that controls the amount of increase in pressure of the compressor 2 in the refrigeration cycle, and the control unit (7) increases the pressure of the compressor (2) in a limited range in which the value of the net positive suction head of the pump (6) does not fall below a predetermined value.-

摘要： A directional valve (1) for installation into a line and a heat pump (100) with a directional valve of this kind (1.1) includes a base body (2) having at least two fluid connections (3, 4). The directional valve (1) further includes a control element (6) that is designed to be switched between at least two switching positions (A, B), of which a passage of flow between the fluid connections (3, 4) is enabled in one switching position (A) and the passage of flow between the fluid connections (3, 4) is blocked in another switching position (B). The directional valve (1) also includes an actuator structure (12) with a jolt property. The actuator structure (12) is designed to switch the control element (6) by way of utilizing its jolt property. Furthermore, the directional valve (1) includes an actuating device (15) for actuating the actuator structure (12).

摘要： A heat pump system provides at least six modes of heating, cooling, and/or domestic water heating operation, where domestic water heating may occur concurrently with heating or cooling a space in a structure. The heat pump system comprises a desuperheater positioned downstream of the compressor and operable as a desuperheater, a condenser or an evaporator, a source heat exchanger operable as either a condenser or an evaporator, a load heat exchanger operable as either a condenser or an evaporator, a reversing valve positioned downstream of the desuperheater heat exchanger and configured to alternately direct refrigerant flow from the desuperheater heat exchanger to one of the load heat exchanger and the source heat exchanger and to alternately return refrigerant flow from the other of the load heat exchanger and the source heat exchanger to the compressor, and an expansion valve positioned between the load heat exchanger and the source heat exchanger.

摘要： A marine air conditioning unit, according to various embodiments, can include a base plate having one or more mounting holes. A main unit is supported on the base plate comprising an evaporator, a compressor, a compressor driver, a condenser, an electronic expansion valve, a blower, an electrical pressure sensor and a condensation pan operatively coupled together. The compressor can be a variable speed inverter brushless direct current (BLDC) compressor. The electronic expansion valve can be located in a refrigerant line connecting the condenser to the evaporator. A controller can constantly receive and, using an algorithm, analyze sensor information from multiple sensors positioned within the main unit. Based on the sensor information, the controller can transmit a control signal to various components and further adjust the electronic expansion valve to control the precise amount of refrigerant to pass to the evaporator.
