Preheating and Drying up the Floor

Preheating and Drying up the Floor

Before floor heating, if a large amount of water remains on the floor, the floor may be warped or even ruptured during floor heating operation. Midea provides drying mode which is used after the initial installation of floor loops and preheating mode for the first heating during seasonal heating in order to protect the floor. During the process, the water temperature would be increased gradually.

Typical Applications

System configurations

System configurations

M thermal system can be configured to run with the electric heater either enabled or disabled and can also be used in conjunction with an auxiliary heat source such as a boiler.

The chosen configuration affects the size of heat pump that is required. Three typical configurations are described below:

Configuration 1: Heat pump only

  • The heat pump covers the required capacity and no extra heating capacity is necessary.
  • Requires selection of larger capacity heat pump and implies higher initial investment.
  • Ideal for new construction in projects where energy efficiency is paramount.

Configuration 2: Heat pump and backup electric heater

  • 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.

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.

One-stop solution - Heating, cooling and domestic hot water in one system

M thermal is an integrated system that provides space heating and cooling as well as domestic hot water, offering a complete, all-year-round solution which can eliminate the need for traditional gas or oil boilers, or work together with them. M thermal can be combined with floor heating loops, fan coil units, radiators and domestic water tanks. It can also be connected to solar collectors, gas furnaces, boilers and other heat sources. Smart Grid certification indicates that M thermal can fully utilize electricity from different sources or different price levels, which means like photovoltaic, and the peak valley of urban electricity supply to satisfy different modes operation, which is benefitial for cost saving.

Practical applications

Midea M-Thermal heat pump systems can be used in various scenarios. Below you will see the most common of them:

Practical applications

Heating and Cooling

Floor heating loops is used for space heating and fan coil unit is used for both space heating and cooling. For heating mode, floor heating loops and fan coil unit require different operating water temperature. To achieve these two temperaturea, a mixing station (field supplied) which is consists of 3-way valve and water pump is used to adapt the water temperature according to requirements of the floor heating loops. The mixing station is controlled by the unit. For cooling mode, 2-way valve is used to prevent cool water from entering floor heating loops then result in condensation during cooling.
