Introduction
How air source heat pump works
Why choose an air source heat pump?
Heat pump units are capable of extracting heat from the surrounding air and transferring this heat indoors for space heating
and domestic hot water.
3kW
Compressor
Evaporator
Condenser
Expansion valve
Heat source
Typically around 3kWh of energy can be captured for every 1kWh of electrical energy expended, giving almost 4kWh of heat
energy for only 1kWh of electrical input and giving efficiency of almost 400%.
1
Heat distribution
Stage One
A
s the refrigerant passes through the expansion valve and expands, its temperature and pressure both drop.
2
Stage Two
With the temperature of the refrigerant being lower than the ambient temperature, heat passes from the air flowing over
the air side heat exchanger to the refrigerant and the refrigerant evaporates.
3
When the refrigerant vapor passes through the compressor, refrigerant pressure increases and temperature rises above that
of the water in hydronic system.

Stage Four
As the hot vapor refrigerant passes through the water side heat exchanger it heats the water in the hydronic system,
which is then pumped indoors to the space heating terminals or hot water tank. The refrigerant cools and
condenses and then ready to return to the expansion valve to start the cycle again.

The M thermal range offers the flexibility to either have the hydronic components installed indoors or outdoors. M thermal has two
different refrigerant series: R32 & R410A. With M thermal Mono, the hydronic components are integrated into the outdoor unit,
offering ease of installation, whilst with M thermal Split the hydronic components are contained in a separate hydronic box, offering
more installation flexibility. Both the Mono and Split products are rated A+++ on the energy efficiency and make a significant
contribution to limiting the impact on the environment.

Mono unit
Split type outdoor unit
Mono unit absorbs heat from the outside air and transfers it to the water in the hydronic modular, through water to
supply heat to indoor side.
The outdoor unit absorbs heat from the outside air and transfers it inside through the refrigerant piping.
Domestic hot water tank
Hot water from the Mono unit is circulated around the domestic hot water tank's heating w
ater coil, heating the domestic hot
water inside the tank. Immersion heaters are often installed in domestic hot water tanks as a backup.
User interface
User interface is connected to the Mono unit through signal wire; it mainly uses for ON/OFF the unit, mode setting, temperature
adjusting and timer setting.
Hydronic box
The hydronic box heats the water by refrigerant from outdoor unit. The heated water circulates through heating apparatus such
as floor heating, radiators, fan coil units as well as inner coil of domestic hot water tank.
Domestic hot water tank
Hot water from the Split unit is circulated around the domestic hot water tank's heating water coil, heating the domestic hot
water inside the tank. Immersion heaters are often installed in domestic hot water tanks as a backup.

Features
High efficiency and wide operating range
Spray liquid cooling control of compressor is benefit for enhancing heating capacity in low temperature condition.
DC Inverter Technology
Guarantee efficiency
The motors traditionally used in heat pumps run at full power even during part-load operation, wasting energy. Midea's M
thermal products use DC inverter technology, which allows precise control of motor speed, ensuring that only the power
necessary to perfectly match the real load is used.
S series: Offers heating capacity of 80% at -7°C thanks to the large heat exchanger and large compressor.
E series: Offers heating capacity of 100% at -7°C thanks to the large heat exchanger and large compressor.
A series: Offers heating capacity of 100% at -10°C thanks to the large heat exchanger and large compressor.
Twin rotary compressor
Twin rotary DC inverter compressor uses 30% less power than traditional scroll compressors whilst also giving a wider
operating frequency range, enabling precise
control and reducing running noise levels.

Month
Finned tube heat exchanger
Stable water temperature improves comfort
Precise control of the compressor rotation speed ensures that the water temperature is maintained within a much smaller range
around the set temperature than is possible with non-inverter systems.
Temperature / Power input
High performance fin-coil type heat exchanger is adopted at air side.
Flat fin strengthens the low temp
erature heating capacity and effectively reduces capacity attenuation.
Hydrophilic film fins and inner-threaded copper pipes optimize heat exchange efficiency.
The specially coated blue fins enhance durability and protect against corrosion from air, water and other corrosive agents, assuresa longer coil service life.

Hydronic module
Brushless DC fan motor
Intergrated hydronic module with DC water pump and backup electric heater.
Stepless fan motor control enables super-quiet fan operation and minimizes power consumption.
Quick start-up
Inverter system output power according to the energy demand by adjusting motor rotary frequency, so it possible to achieve
comfort conditions in less time than system without inverter, start-up time reduced.
Less frequent star
t/stop
The ability to vary compressor speed (as opposed to simple on/off control) means that the compressors experience fewer
start/stop cycles which expands compressor lifespan and reduces noise.
Quiet operation
Most of the time, the capacity required for heating/cooling is lower than the peak load condition, meaning that heat pumps work
under part-load conditions most of the time. With DC inverter compressors adjusting rotation speed according to the actual load
requirement, noise levels are lower than with traditional compressor technology.
For S and E series
For A series
For E series and A series and S series model MHC-V5(7/9)W/D2N1, backup electric heater is customizable whilst other
S series models are standard mounted for additional heating during extremely cold weather. The capacity of the backup
electric heater is customizable and the output capacity is adjustable.
Heating, cooling and domestic hot water: a total heat solution.
Compatible with additional heat sources (AHS)
including solar water heaters and boilers. AHSs can work together
with heat pump or alternative for space heating and domestic hot water dependent on the system control.

(No more heating)
Configuration 1: Heat pump only

Ideal for new construction in projects where energy efficiency is paramount.
Configuration 2: Heat pump and backup elec
tric heater
USB function(For A Series)
Convenient program upgrade
Heat pump covers the required capacity until the ambient temperature drops below the point at
which the heat pump is able to provide sufficient capacity. When the ambient temperature is
below this equilibrium point, the backup electric heater supplies the required additional heating
capacity.
Best balance between initial investment and running costs, results in lowest lifecycle cost.
Ideal for new construction.
No need to carry any other heavy equipments but only USB can realize program upgrade of indoor unit and outdoor unit.
Parameter setting transmission between wired controllers
Installer can quickly copy the setting from one controller to another via USB, which save the time of on-site installation.
Configuration 3: Heat pump with auxiliary heat source
Heat pump covers the required capacity until the ambient temperature drops below the point at
which the heat pump is able to provide sufficient capacity. When the
ambient temperature is
below this equilibrium point, depending on the system settings, either the auxiliary heat source
supplies the required additional heating capacity or the heat pump does not run and the auxiliary heat source covers the required capacity.
Enables selection of lower capacity heat pump.
Ideal for refurbishments and upgrades.

Typical Applications

Application 1:Space Heating Through Floor Heating Loops and Fan Coil Units
Application 1: Space Heating Only
The room thermostat is used as a switch. When there is a heating request from the room thermostat, the Mono unit
operates to achieve the target water temperature set on the user interface. When the room temperature reaches the
thermostat’s set temperature, the unit stops.
The floor heating loops and fan coil units require different operating water temperatures. To achieve these two set
points, a mixing station is required. Room thermostats for each zone are optional.
