Wall-mounted heat pump

The power

The power (or capacity) of your wall unit has a direct impact on your comfort level. To make the right choice, you need to take into account not only your living area, but also your home’s configuration, fenestration, level of sunlight and insulation.

The quick selection chart below will guide you in estimating the power you need. Used by Entreprises MPH for over 15 years, this chart is based on heat load calculations for a bungalow (standard one-storey open-plan house).

Power output by square footage

That said, if in doubt, it’s advisable to call on air-conditioning professionals. They’ll be able to determine the ideal wattage for your home, as well as the best location for the unit. Your comfort is at stake.

A heat pump that’s too powerful for your needs will cool the air too quickly, preventing humidity from escaping properly. For comfortable room air, it should be neither too dry nor too humid. In summer, the ideal humidity level is between 40% and 50%. During the cold season, we aim for 30%.

Noise level

Wall-mounted units are becoming increasingly quiet. To compare the sound levels of the different models on the market, you need to check the number of decibels (dB).

There are two main variants to consider: the indoor unit and the outdoor unit.

– Indoor unit (evaporator): the fan speed must be indicated on the data sheet, along with the air flow rate (CFM) and noise level (dB). As a guide, the quietest model currently available for the indoor unit is the LG Prestige at 17 dB.

– Outdoor unit (condenser): operating noise is given in dB at the highest speed in the data sheets. The quietest units at present are the LG Prestige and the Fujitsu RLS3 and RLS3H with 43 dB for the outdoor unit.

Note that models with an Inverter compressor are quieter than those with an ON/OFF compressor.

Energy efficiency ratings

Seasonal Energy Efficiency Ratio (SEER) and Heating Seasonal Performance Factor (HSPF) are displayed on the wall-mounted heat pump’s yellow Energy Guide label.

SEER: the ratio of cooling capacity (BTU/h) divided by the unit’s gross energy consumption (kWh or Watt/h). The higher the SEER ratio, the lower the heat pump’s efficiency.

HSPF: this is the ratio between the heating capacity in (BTU/h) divided by the unit’s gross energy consumption (kWh or Watt/h). The higher the HSPF ratio, the less energy the unit consumes in heating mode.

When making your purchase, HSPF is a very important factor to consider. Generally speaking, we estimate that a heat pump with an HSPF of 14 can save you up to $500 on your annual heating bill (taking into account the energy consumed during the cooling months). In comparison, a unit with an HSPF of 9 will save you around $200.

You may also have heard of the energy efficiency ratio (EER or EER). This value is mainly used by air-conditioning engineers and technicians.

The coefficient of performance (COP) measures the efficiency of your heat pump for heating. All units have a COP, but some manufacturers don’t display their technical data.

Precise temperature control inside your home

An inverter compressor is more precise when it comes to temperature, because it’s able to vary its power continuously and precisely. Unlike traditional compressors, which operate either at full power or at a standstill, an inverter compressor can adjust its speed in real time to meet your home’s heating or cooling needs.

Using a temperature sensor located inside the evaporator, the inverter compressor constantly receives information about the ambient temperature and can adjust its speed accordingly to reach the desired temperature more precisely and quickly. This helps maintain a more stable, comfortable temperature, with fewer undesirable fluctuations.

In addition, inverter compressors are often combined with sophisticated electronic control systems that enable precise temperature control and greater energy efficiency, which can significantly reduce heating and cooling costs while providing greater comfort.

Increased energy savings

The compressor dramatically reduces its output when the temperature is reached, providing you with only the BTU/h required to maintain the temperature.

Inverter compressors use a variable-speed motor, which means the compressor speed can be adjusted according to cooling demand. Unlike conventional compressors, which switch on and off to maintain the desired temperature, the inverter compressor adjusts its speed in real time to respond to fluctuations in indoor temperature.

This allows the inverter compressor to run at lower energy levels when the indoor temperature is close to the desired temperature, whereas traditional compressors always run at full power and switch off when the temperature is reached, consuming more energy.

Better dehumidification

A wall-mounted heat pump with an inverter compressor offers better dehumidification because it allows more precise regulation of compressor speed, so that the air-conditioning system’s dehumidification capacity can be adjusted according to demand.

When air humidity is high, an inverter compressor can operate at a higher speed to increase dehumidification capacity, which in turn increases the cooling capacity.

What’s more, the inverter compressor can maintain a constant speed as dehumidification demand changes, unlike conventional compressors which have to switch on and off to maintain the desired temperature. This enables the air-conditioning system to operate more stably and efficiently, reducing humidity more consistently.

By reducing air humidity, an inverter compressor can help prevent the growth of mold and bacteria, which can improve indoor air quality and reduce health risks.

Longer service life

An inverter compressor has a longer service life for several reasons:

Variable-speed operation: The inverter compressor operates at variable speed rather than constant speed, which reduces wear and fatigue on the compressor. Conventional compressors run at full speed when running, which can lead to premature wear of compressor parts.

Pressure regulation: The inverter compressor regulates the pressure in the air-conditioning system to maintain a constant temperature. This reduces the workload on the compressor and extends its service life.

Reduced energy consumption: Variable-speed operation reduces the energy consumption of the air-conditioning system. Less energy consumption means less heat generated and less stress on the compressor, extending its service life.

Reduced wear and tear on the air-conditioning system: Precise regulation of air temperature and humidity by the inverter compressor reduces the workload on other air-conditioning system components, such as fans and heat exchangers. This also extends the service life of the air-conditioning system as a whole.

Inverter compressors are designed to operate more efficiently and more stably, reducing wear and fatigue on air-conditioning system components, thus extending the life of the compressor and the system as a whole.

Much quieter compressor

A wall-mounted heat pump with an Inverter compressor is much quieter than one with an ON/OFF compressor, because the compressor starts slowly and gradually increases speed to maximize energy consumption. This allows the oil to circulate more efficiently, avoiding start-up bumps and ensuring quieter operation.

Conventional compressors run at full speed when running, which can generate high noise levels. Inverter compressors, on the other hand, are designed to run at lower speeds when the demand is high.

What’s more, the inverter compressor’s precise regulation of air temperature and humidity also reduces the workload on other air-conditioning system components, such as fans and heat exchangers. It also reduces the overall noise generated by the air-conditioning system.

By reducing the noise level generated by the compressor and the air-conditioning system as a whole, an inverter compressor can improve the comfort of the occupants of the home or air-conditioned space. In addition, it can reduce noise disturbance for neighbors or other occupants of the building or surrounding area.

How an Inverter compressor works

The frequency inverter communicates with the indoor temperature sensor in the evaporator to vary the compressor speed. The compressor is specifically designed to operate at different speeds to modulate heating power according to the required temperature. Precise refrigerant quantity is a critical requirement to ensure compressor life. In addition, proper oil management ensures adequate lubrication for low-speed operation and prevents excessive oil injection into the circuit during full-speed operation.

The inverter compressor uses a variable-speed motor that enables the compressor to operate at different speeds depending on the cooling or heating demand. Unlike conventional compressors, which switch on and off to maintain the desired temperature, the inverter compressor adjusts its speed in real time to respond to fluctuations in indoor temperature.

When the indoor temperature is higher than the desired temperature, the inverter compressor starts at a low speed and gradually increases its speed to reach the required cooling capacity. Compressor speed is regulated according to cooling demand, enabling the cooling capacity of the air-conditioning system to be adjusted as required.

On the other hand, if the ambient temperature is lower than the desired temperature, the inverter compressor reduces its speed or stops altogether to save energy. Variable speed therefore reduces the energy consumption of the air-conditioning system, as the compressor only runs at the speed required to maintain the desired temperature.

In addition, the inverter compressor regulates the pressure in the air-conditioning system to maintain a constant temperature, reducing the workload on the compressor and extending its service life.
