MHIAE offer a wide range of condensing units from 4 to 48hp to provide a solution for all applications, both large and small. The units’ compact design keeps cost and environmental impact to a minimum whilst saving you space, and long pipe lengths give you flexibility when it comes to installing. A large heating and cooling operation range mean the units will work in tricky conditions. Units from 8 to 48hp are also available in Heat Recovery systems, which provide simultaneous heating and cooling to individual indoor units according to the requirements of each room. 3D scroll compressors provide the units with higher efficiency, higher endurance and all at a more condensed size.

Guaranteed Operating Range: Cooling -5ºC ~ +46ºC; Heating -20ºC ~ +21ºCAir conditioner & heat pump controls & switches: This article explains the function, location, identification & use of all air conditioning & heat pump system operating controls. Photos and text help you to find & recognize each of these controls and the text explains what the control does. We include links to detailed diagnosis & repair articles related to the various HVACR controls & swtiches. We also review the basic air conditioning safety switches, contactors, relays, refrigerant metering devices, motor overolad switches, relays, resets. Also see A/C - HEAT PUMP CONTROLS & SWITCHES where we list all Air Conditioning & Heat Pump System Controls & Switches, and see THERMOSTATS. This chapter is part of our extensive air conditioning inspection, diagnosis, & repair document which describes the inspection, diagnosis, and repair of residential air conditioning systems (A/C systems) for home buyers, owners, and

Safety disconnects should installed outside next to the compressor/condenser unit and are often also installed next to or mounted on the air handler/blower unit. If you cannot find an outside electrical disconnect at your compressor/condenser unit, one should be installed. These controls are recommended for safety to reduce the temptation to open the cabinet and work on the equipment with power on. Working on electrically "live" cooling equipment risks both shock and mechanical injury such as being cut by the fan if the motor startsSafety shutoffs are required for new equipment. See A/C - HEAT PUMP CONTROLS & SWITCHES for details. Our photograph of a modern circuit breaker panel (left) shows where your search for the air conditioning or heat pump system main circuit breakers would typically begin. Look for two control circuits for the air conditioner or heat pump system that will typically include: The safety switch on newer equipment may be a simple pull-out fuse-block type power disconnect, leaving circuit protection to be provided only at the circuit breaker

or fuse for the A/C circuit where it originates in the electrical panel. Where the actual overcurrent protection is provided (at older circuit breakers used as auxiliary safety disconnects at the equipment, and at the main panel at the origin of the cooling circuit for the compressor/condenser unit) electrical overload protection size (circuit breaker or fuse amperage rating) for modern A/C equipment is specified by the manufacturer. The Maximum Fuse or HACR type Breaker: specifies the maximum overcurrent protection or MOP to be used to protectThe permitted ampacity of the equipment electrical circuit protection (fuse or circuit breaker amps) expressed as MOP or Maximum Overcurrent Protection. If MOP is specified, the breaker or fuse protecting the equipment should match this number. As we explained at the beginning of this document, a hermetic compressor draws varying amounts of current (measured in amps) as its internal pressure changes during operation.

We said that current draw is higher when starting the motor than when the system is in Current draw is highest if the motor is starting against its highest back pressure such as if the air conditioning system has been turned off and then back on in the middle of operation. Because fusing an air conditioning compressor at the minimum level can result in blown fuses or tripped breakers during these intervals of heavy current draw during compressor startup, compressors are either protected by a slow-blow fuse or a somewhat larger than minimum circuit breaker.] On some older equipment MOP is not specified. Only when MOP has not been specified can the overcurrent protection required be determined by alternative means such as [RLA OR BCSC whichever is greater x 175%], or if the compressor keeps tripping that device or blowing that fuse, RLA x 225% might be used. The National Electrical Code (NEC) specifies the degree to which a breaker or fuse may exceed the RLA.

[For example, if the MOP or fuse size is specified by the manufacturer to be 40 amps, then a 40 amp breaker must be installed with no increase or change in that rating.] Multiple switches are often present on cooling systems. As we reminded in the previous chapter, if the air conditioning system won't run, before requesting a service call check all of the switches as well as the thermostat for proper settings. When the air conditioning system is running, if you measured the amperage, it would be roughly 80% of the RLA. The breaker size is typically about 125% of the total of the compressor RLA and the condenser fan FLA (full load amperage). We are referring here to the main circuit breaker that controls the air conditioner compressor/condenser unit - a switch that is typically located in the main electrical panel or in a sub-panel serving the air conditioning or heat pump equipment. Our photo at left shows a different switch: an outside service switch that incorporates a circuit breaker next to the compressor/condenser.

This circuit is for use by the service technician and because it is downstream of the wire bringing power to the compressor/condenser unit, it is not protecting that wire from an overcurrent. While both of these circuit circuit breakers must be properly served, don't confuse their role nor their location. The rationale is that the circuit breaker protecting the air conditioner compressor unit should trip in the event of a locked rotor [the revolving axle of a compressor motor, for example] or some significant electrical event, but should not trip during start up loads which, as we know can be significantly higher than the RLA momentarily [as the compressor motor draws higher amperage to get itself started]. An air conditioning electrical circuit is different than a general household circuit in that we have a known current load. only one device connected to the air conditioning electrical circuit, and we can read its operating characteristics.] We are not worried about an overload situation where people plug several appliances into receptacles on a single circuit.
