    Abstract: The disclosed technology includes an on-demand water heater which uses a heat pump to heat the fluid. The on-demand heat pump water heater can have a low fluid capacity heating chamber which has an inlet and an outlet, a heat pump for heating the fluid, and a controller to control the heat pump and maintain the temperature of the fluid at a predetermined temperature. The on-demand heat pump water heater can include one or more temperature sensors, flow sensors, fluid mixing valves, or supplemental heat sources.

    Abstract: A self-contained ventilation apparatus is disclosed for ventilating buildings, e.g., patient rooms such as hospital rooms, waiting rooms, hospital operating rooms, doctors' offices, and clinics, especially rooms contaminated with infectious microorganisms. One or more blowers is provided. When there are two blowers, a first blower is provided for discharging room air to the atmosphere and a second blower is provided for introducing fresh outside air to the room to provide a continuous supply of fresh air to the room which is free of disease organisms. Both streams of air pass through an air-to-air heat exchanger to adjust the temperature of the incoming air to approach that exhausted from the room. When filters are used, both currents of air are preferably filtered, e.g., with a high efficiency particle air (HEPA) filter. Provision is made for automatically maintaining room air pressure at the desired value (typically below that of surrounding rooms) as filters gradually become clogged with dust. Supplemental heat or cold is supplied to incoming air by locating semiconductive thermoelectric cooling modules between incoming and outgoing air streams. Optional thermoelectric modules also dehumidify or warm incoming air depending on the season.

    Abstract translation: 公开了一种独立的通风装置，用于通风建筑物，例如病房，例如医院室，候诊室，医院手术室，医生办公室和诊所，特别是被感染性微生物污染的房间。 提供一个或多个鼓风机。 当有两个鼓风机时，提供第一鼓风机用于将空气排放到大气中，并且提供第二鼓风机用于将新鲜的外部空气引入到房间中，以便向没有疾病生物体的房间提供连续的新鲜空气供应。 两股空气流通过空气 - 空气热交换器以调节进入空气的温度接近从房间排出的温度。 当使用过滤器时，空气的两个电流优选地被过滤，例如利用高效率的颗粒空气（HEPA）过滤器。 规定，随着过滤器逐渐被灰尘堵塞，​​将室内空气压力自动保持在所需值（通常低于周围房间的空气压力）。 通过在进入和输出的空气流之间定位半导体热电冷却模块，向进入的空气供应补充的热量或冷气。 可选择的热电模块也根据季节进行除湿或加热进气。

    Abstract: The present invention relates to a method for alleviating a short-term "cold blow" effect in a heat pump heating system. According to a method of the invention, reversing of a system valve in response to the sensing of a defrost condition is delayed by a predetermined time. The amount of this delay time depends upon the amount of time required for a supplementary heating unit to achieve an output sufficient to offset the cooling effect resulting from there being a cold indoor coil.

    Abstract: The invention concerns thermoelectric coolers/heaters of the kind comprising at least one thermoelectric block and heat-exchanging means consisting, at least on one side of the block, of metallic convector elements over which sweeps a fan-generated current of forced air. In accordance with the invention the convector element is formed by squarely cut, extruded profile members having longitudinally extending portions forming fins and channels The fan is an axial fan the impeller (22) of which spans most of the cross-sectional area of the convector element (7), and the convector profile member has means (9; 23) to secure the fan unit in position.

    Abstract: The delivery side of a refrigerant compressor is connected through an inside heat exchanger to a refrigerant heater, the outlet side of the refrigerant heater being connected with the suction side of the compressor. First and second temperature sensors are provided at inlet and outlet sides of the refrigerant heater, respectively for sensing inlet and outlet refrigerant temperatures. A fuel gas supply unit for the refrigerant heater is fitted with a fuel gas control value which is controlled by the temperature differences existing between sensed temperatures by the first and second sensors.
