Abstract: The present application provides an adapter (20) for a manifold gauge assembly (1) for use on a fluid system, for example an HVAC-R system. The manifold gauge assembly (1) comprises a manifold (3) for connection to the fluid system, and a pressure gauge (14) arranged to detect a fluid pressure in the manifold (3). The adapter (20) comprises a tube (23) having connectors (27, 28) for fluidly connecting the adapter (20) to the pressure gauge (14) and to the manifold (3). The adapter also includes an electronic pressure sensor (21) arranged to detect a fluid pressure in the tube (23), and a communications unit (22) configured to receive data from the electronic pressure sensor (21) and to communicate with a remote device (32).

Abstract: A bracket for securing a device to an elongate structure, the bracket comprising a body configured to hold the device, and a securing element attached to the body. The securing element comprises a pair of bosses, each boss comprising a slot, a core and an end surface. The bosses are arranged on the securing element such that the end surfaces define a gap into which the elongate structure can be received when the securing element is in a first position relative to the elongate structure and the slots are configured to receive the elongate structure upon rotation of the securing element from the first position to a second position relative to the elongate structure. The bracket is secured to the elongate structure by a gripping inter-engagement of the elongate structure and the bosses of the securing element in said second position.

Abstract: The present application provides apparatus (15) for connection to an HVAC-R system during maintenance or commissioning. The apparatus includes a plurality of ports (16, 17, 18) for fluid connection to the HVAC-R system and to maintenance apparatus, for example a refrigerant tank, a refrigerant recovery unit and/or a vacuum pump. The apparatus also includes a plurality of fluid connections (20) between the plurality of ports, each of the plurality of fluid connections having an electrically actuatable valve (21) to open and close the fluid connection. The apparatus also includes a control unit configured to control each of the electrically actuatable valves to configure the plurality of fluid connections.

Abstract: The present disclosure comprises a method of controlling a condensate pump assembly which comprises a pump and a controller connected to the pump, the method comprising measuring a current value drawn by the pump, comparing the measured current value to a predetermined threshold current value and controlling operation of the condensate pump assembly based on the current value comparison. Also provided is a condensate pump assembly for use in an air conditioning system, comprising a housing comprising an upper housing portion and a pump arranged to pump liquid from a liquid inlet to a liquid outlet.

Abstract: A pump comprising a housing; a motor mounted in the housing and configured to drive a rotor mounted on a shaft connected to the motor, and a first connector and a second connector each secured to the housing. The first and second connectors are in fluid communication by a tube arranged in the housing. The first connector is configured to connect to a first fluid line and the second connector is configured to connect to a second fluid line. In use, the rotor is configured to urge fluid within the tube from the first connector to the second connector when driven by the motor. The first and second connectors are releasably secured to the housing.

Abstract: The present application provides a vacuum pump (15) for use during maintenance or commissioning of an HVAC-R system (1). The vacuum pump (15) has a pump (17) having a pump intake (22) for connection to the HVAC-R system (1), in particular one or more of a high pressure service port (14) and a low pressure service port (13) of the HVAC-R system (1). The vacuum pump (15) also includes a communications unit (19) that is configured to connect to a mobile communications network. The vacuum pump (15) also includes a pressure sensor arranged to detect a pressure in the HVAC-R system (1). The vacuum pump (15) also includes a control unit (18) configured to receive pressure data from the pressure sensor (21), control operation of the pump (17), and communicate with a remote device via the communication unit (19) and the mobile communications network. In examples, the remote device (20) may be a mobile phone or a tablet computer, or any device that can connect to a mobile communications network.
